+description: 创建 PolyHermes 项目的 GitHub Release。当用户要求发布版本、创建 release、打 tag 或发布新版本时使用。
+---
+
+# Create Release
+
+创建 PolyHermes 项目的 GitHub Release，包括创建 Git tag、推送 tag、创建 GitHub Release（支持 pre-release），并自动在 Issue #1 发布公告。
+
+## 使用时机
+
+- 用户要求「发布版本」「创建 release」「打 tag」「发布新版本」时
+- 用户要求「创建 pre-release」「beta 版本」时
+- 用户提到「v1.x.x」等版本号相关操作时
+
+## 前置条件
+
+1. **GitHub CLI 已安装**：确保 `gh` 命令可用
+2. **已登录 GitHub**：运行 `gh auth status` 确认
+3. **工作目录干净**：建议先提交所有更改
+
+## 指令
+
+### 步骤 1：收集发布信息
+
+询问用户以下信息：
+- 版本号（格式：vX.Y.Z，如 v1.0.0）
+- 是否为 Pre-release（测试版本）
+- Release 标题和描述（可选，如未提供则自动生成）
+
+### 步骤 2：生成 Release 内容
+
+**重要**：如果用户未提供描述，需要根据 Git commits 自动生成。
+
+1. **获取上一个版本的 tag**：
+   ```bash
+   git describe --tags --abbrev=0 HEAD
+   ```
+
+2. **获取版本间的 commits**：
+   ```bash
+   git log <PREVIOUS_TAG>..HEAD --oneline --no-merges
+   ```
+
+3. **过滤 commit 规则**：
+   - **排除**：版本内新增功能的修复 commit
+   - **判断方法**：如果一个 commit 的消息包含「fix」「修复」「bugfix」等关键词，且是针对同一版本内新增代码的修复，则不包含
+   - **保留**：新功能、性能优化、重构、文档更新等
+
+4. **生成中英文 Release 内容**：
+   - 格式要求：**中文在上，英文在下**
+   - 使用分隔线 `---` 分隔中英文部分
+   - 按功能类型分组（新功能、改进、修复等）
+
+   示例格式：
+   ```markdown
+   ## 新功能
+
+   - 添加了 A 功能
+   - 支持了 B 操作
+
+   ## 改进
+
+   - 优化了 C 性能
+
+   ---
+
+   ## New Features
+
+   - Added feature A
+   - Supported operation B
+
+   ## Improvements
+
+   - Optimized performance C
+   ```
+
+### 步骤 3：运行发布脚本
+
+在项目根目录下执行：
+
+```bash
+cd .cursor/skills/common/create-release/scripts && \
+chmod +x create-release.sh && \
+./create-release.sh -t <VERSION> [-T "<TITLE>"] [-d "<DESCRIPTION>"] [-p] [-y]
+```
+
+### 步骤 4：发布公告到 Issue #1
+
+**重要**：Release 创建成功后，必须自动在 Issue #1 下发布公告 comment。
+
+1. **生成公告内容**（面向用户，通俗易懂）：
+
+   公告格式模板：
+   ```markdown
+   # 🎉 PolyHermes vX.X.X 版本发布公告
+
+   ## 📅 发布日期
+
+   YYYY年MM月DD日
+
+   ---
+
+   ## ✨ 本次更新亮点
+
+   ### 🚀 新功能
+
+   **功能名称**
+   - 用通俗的语言描述这个功能是什么
+   - 用户能从中获得什么好处
+   - 如何使用这个功能
+
+   ### 🔧 改进优化
+
+   - 优化了 XXX，现在 XXX 更快/更稳定了
+   - 改进了 XXX 体验，操作更简单了
+
+   ### 🐛 问题修复
+
+   - 修复了 XXX 问题，不再出现 XXX 情况
+
+   ---
+
+   ## 📦 如何更新
+
+   ### Docker 部署（推荐）
+
+   ```bash
+   # 拉取最新镜像
+   docker pull wrbug/polyhermes:vX.X.X
+
+   # 重启服务
+   docker-compose -f docker-compose.prod.yml down
+   docker-compose -f docker-compose.prod.yml up -d
+   ```
+
+   ---
+
+   ## ⚠️ 安全提醒
+
+   **请务必使用官方 Docker 镜像源，避免财产损失！**
+
+   **官方镜像地址**：`wrbug/polyhermes`
+
+   ---
+
+   ## 📚 相关链接
+
+   - **GitHub Release**: https://github.com/WrBug/PolyHermes/releases/tag/vX.X.X
+   - **Docker Hub**: https://hub.docker.com/r/wrbug/polyhermes
+   ```
+
+2. **公告内容编写原则**：
+
+   - ✅ **通俗易懂**：避免技术术语，用用户能理解的语言
+   - ✅ **突出价值**：告诉用户这个更新对他们有什么好处
+   - ✅ **简洁明了**：每个功能点用 1-2 句话说明
+   - ✅ **包含操作指引**：告诉用户如何使用新功能
+   - ✅ **中英文双语**：中文在上，英文在下（可选）
+   - ❌ **避免**：commit hash、代码细节、内部实现
+
+3. **执行发布公告命令**：
+
+   ```bash
+   gh issue comment 1 --repo WrBug/PolyHermes --body "$(cat <<'EOF'
+   # 🎉 PolyHermes vX.X.X 版本发布公告
+
+   [公告内容...]
+
+   ---
+   EOF
+   )"
+   ```
+
+   或使用文件方式（内容较长时推荐）：
+
+   ```bash
+   echo "[公告内容...]" > /tmp/announcement.md
+   gh issue comment 1 --repo WrBug/PolyHermes --body-file /tmp/announcement.md
+   ```
+
+### 参数说明
+
+| 参数 | 说明 | 示例 |
+|------|------|------|
+| `-t, --tag` | 版本号（必需） | `-t v1.0.0` |
+| `-T, --title` | Release 标题 | `-T "Release v1.0.0"` |
+| `-d, --description` | Release 描述 | `-d "## 新功能\n- 功能1"` |
+| `-f, --description-file` | 从文件读取描述 | `-f CHANGELOG.md` |
+| `-p, --prerelease` | 标记为 Pre-release（自动加 -beta 后缀） | `-p` |
+| `-y, --yes` | 无交互模式 | `-y` |
+
+## 版本号格式
+
+- 必须格式：`v数字.数字.数字`（如 v1.0.0, v1.10.2, v1.1.12）
+- 如果指定 `--prerelease`，会自动拼接 `-beta` 后缀（如 v1.0.1 → v1.0.1-beta）
+
+## Release 内容生成规则
+
+### 中英文格式
+
+Release 描述**必须**使用中英文双语格式：
+
+```markdown
+## 中文标题
+
+- 内容项1
+- 内容项2
+
+---
+
+## English Title
+
+- Item 1
+- Item 2
+```
+
+### Commit 过滤规则
+
+**需要排除的 commit 类型**：
+
+1. **版本内修复**：对同一版本新增功能的后续修复
+   - 例如：v1.0.1 新增了功能 A，然后有一个 commit 修复功能 A 的 bug → 不包含
+   - 判断依据：commit 消息包含「fix」「修复」「bugfix」且相关功能在本版本新增
+
+2. **琐碎修改**：
+   - typo 修正
+   - 代码格式调整
+   - 注释更新
+
+**需要保留的 commit 类型**：
+
+1. 新功能（feat、feature）
+2. 改进/优化（improve、optimize、enhance）
+3. 重要 bug 修复（针对旧版本的 bug）
+4. 重构（refactor）
+5. 文档更新（docs）
+
+### 分组建议
+
+- **新功能 / New Features**
+- **改进 / Improvements**
+- **修复 / Bug Fixes**（仅包含对旧版本 bug 的修复）
+- **其他 / Others**
+
+## 公告内容示例
+
+以下是一个面向用户的公告示例：
+
+```markdown

-# PolyHermes 一键部署脚本使用说明
+# PolyHermes One-Click Deployment Script / PolyHermes 一键部署脚本使用说明
+
+[English](#english) | [中文](#中文)
+
+---
+
+<a name="english"></a>
+## English
+
+## ✨ Core Features
+
+- **Run from any directory** - No need to download source code
+- **Online images only** - Pull official images from Docker Hub
+- **Auto-download config** - Download the latest `docker-compose.prod.yml` from GitHub
+- **Interactive configuration** - User-friendly Q&A style configuration wizard
+- **Auto-generate secrets** - All sensitive configurations will auto-generate secure random values on Enter
+
+## 🚀 Quick Start
+
+### One-Click Installation (Recommended)
+
+**Using curl (Recommended):**
+```bash
+mkdir -p ~/polyhermes && cd ~/polyhermes && curl -fsSL https://raw.githubusercontent.com/WrBug/PolyHermes/main/deploy-interactive.sh -o deploy.sh && chmod +x deploy.sh && ./deploy.sh
+```
+
+**Using wget:**
+```bash
+mkdir -p ~/polyhermes && cd ~/polyhermes && wget -O deploy.sh https://raw.githubusercontent.com/WrBug/PolyHermes/main/deploy-interactive.sh && chmod +x deploy.sh && ./deploy.sh
+```
+
+This command will automatically:
+- 📁 Create a dedicated working directory `~/polyhermes`
+- 📥 Download the deployment script
+- ✅ Check Docker environment
+- ⚙️ Configure all parameters interactively (press Enter for defaults)
+- 🔐 Auto-generate secure random secrets
+- 🚀 Download latest images and deploy
+
+**Or run directly via pipe (without saving file):**
+```bash
+# curl method
+mkdir -p ~/polyhermes && cd ~/polyhermes && curl -fsSL https://raw.githubusercontent.com/WrBug/PolyHermes/main/deploy-interactive.sh | bash
+
+# wget method
+mkdir -p ~/polyhermes && cd ~/polyhermes && wget -qO- https://raw.githubusercontent.com/WrBug/PolyHermes/main/deploy-interactive.sh | bash
+```
+
+### Method 1: Download and Run Script Directly
+
+```bash
+# Download script
+curl -O https://raw.githubusercontent.com/WrBug/PolyHermes/main/deploy-interactive.sh
+
+# Add execute permission
+chmod +x deploy-interactive.sh
+
+# Run
+./deploy-interactive.sh
+```
+
+### Method 2: Run in Project Directory
+
+```bash
+git clone https://github.com/WrBug/PolyHermes.git
+cd PolyHermes
+./deploy-interactive.sh
+```
+
+## 📝 Usage Flow
+
+After running the script, you will be guided through the following steps:
+
+```
+Step 1: Environment Check  → Check Docker/Docker Compose
+Step 2: Configuration       → Interactive input (press Enter for defaults)
+Step 3: Get Deploy Config   → Download docker-compose.prod.yml from GitHub
+Step 4: Generate Env File   → Auto-generate .env
+Step 5: Pull Docker Images  → Pull latest images from Docker Hub
+Step 6: Deploy Services     → Start containers
+Step 7: Health Check        → Verify services are running properly
+```
+
+## ⚡ Simplest Usage
+
+**Press Enter for all configuration items to use default values**, the script will automatically:
+- Use port 80 (application) and 3307 (MySQL)
+- Generate 32-character database password
+- Generate 128-character JWT secret
+- Generate 64-character admin reset key
+- Generate 64-character encryption key
+- Configure reasonable log levels
+
+### Interactive Example
+
+The script will prompt you for configuration one by one, **press Enter to skip and use default values**:
+
+```
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+  Step 2: Configuration
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+💡 All configurations are optional, press Enter to use default or auto-generated values
+
+⚠ Secret config: Press Enter to auto-generate secure random secrets
+⚠ Other config: Press Enter to use default values in parentheses
+
+【Basic Configuration】
+Will configure: Server port, MySQL port, Timezone
+➤ Server port [Default: 80]: ⏎
+➤ MySQL port (external access) [Default: 3307]: ⏎
+➤ Timezone [Default: Asia/Shanghai]: ⏎
+
+【Database Configuration】
+Will configure: Database username, Database password
+➤ Database username [Default: root]: ⏎
+➤ Database password [Enter to auto-generate]: ⏎
+[✓] Database password auto-generated (32 characters)
+
+【Security Configuration】
+Will configure: JWT secret, Admin password reset key, Data encryption key
+➤ JWT secret [Enter to auto-generate]: ⏎
+[✓] JWT secret auto-generated (128 characters)
+➤ Admin password reset key [Enter to auto-generate]: ⏎
+[✓] Admin reset key auto-generated (64 characters)
+➤ Encryption key (for API Key encryption) [Enter to auto-generate]: ⏎
+[✓] Encryption key auto-generated (64 characters)
+
+【Log Configuration】
+Will configure: Root log level, Application log level
+Available levels: TRACE, DEBUG, INFO, WARN, ERROR, OFF
+➤ Root log level (third-party libs) [Default: WARN]: ⏎
+➤ Application log level [Default: INFO]: ⏎
+
+【Other Configuration】
+Will configure: Runtime environment, Auto-update policy, GitHub repo
+➤ Spring Profile [Default: prod]: ⏎
+➤ Allow prerelease updates (true/false) [Default: false]: ⏎
+➤ GitHub repository [Default: WrBug/PolyHermes]: ⏎
+```
+
+## 🔧 Files Generated by Script
+
+After running, the script will generate in the current directory:
+
+1. **docker-compose.prod.yml** - Docker Compose config downloaded from GitHub (always latest)
+2. **.env** - Environment variables file auto-generated based on your configuration
+
+These two files contain all the configuration needed to run PolyHermes.
+
+## 🌐 Post-Deployment Management
+
+### Quick Update (Recommended)
+
+If you already have configuration files, running the script again will detect and ask:
+
+```bash
+./deploy-interactive.sh
+```
+
+```
+【Existing Configuration Detected】
+Found existing .env configuration file
+
+Use existing configuration to update images directly? [Y/n]: ⏎
+```
+
+- **Press Enter or input Y**: Use existing config, pull latest images and update
+- **Input N**: Reconfigure (existing config will be backed up)
+
+### Manual Management Commands
+
+```bash
+# View service status
+docker compose -f docker-compose.prod.yml ps
+
+# View logs
+docker compose -f docker-compose.prod.yml logs -f
+
+# Restart services
+docker compose -f docker-compose.prod.yml restart
+
+# Stop services
+docker compose -f docker-compose.prod.yml down
+
+# Update to latest version
+docker pull wrbug/polyhermes:latest
+docker compose -f docker-compose.prod.yml up -d
+```
+
+## 🔐 Security Recommendations
+
+- **Protect .env file**: Contains sensitive information, never commit to version control
+- **Backup database regularly**: Data is stored in Docker volume `mysql-data`
+- **Configure HTTPS for production**: Recommend using Nginx or Caddy as reverse proxy
+

+# AUTO 最小价差：100%→50% 动态系数方案
+
+## 现状
+
+- **BinanceKlineAutoSpreadService**：拉取历史 K 线 → IQR 剔除异常值 → 求平均得到「基础价差」→ **固定 ×0.7** 后缓存。
+- 预加载（周期开始时）：`computeAndCache()` 计算并缓存的是 **已乘 0.7** 的值。
+- 触发时：`getAutoMinSpread()` 直接返回缓存值，等价于始终用 **70%** 的系数。
+
+问题：70% 固定，无法随周期内时间变化放宽或收紧。
+
+---
+
+## 目标
+
+1. **预加载提供 100% 数值**：缓存里存「基础价差」（IQR 平均），不再乘 0.7，即预加载 = 100% 基准。
+2. **系数随区间时间点动态递减**：从 **100%** 线性递减到 **50%**，根据「当前时间在区间内的进度」计算。
+
+---
+
+## 方案一：按「触发窗口」进度（推荐）
+
+**区间**：策略的触发窗口 `[periodStartUnix + windowStartSeconds, periodStartUnix + windowEndSeconds]`。
+
+- 窗口起始：系数 = **100%**（最严，价差要求最高）。
+- 窗口内时间越靠后，系数越小；窗口结束：系数 = **50%**（最松，更容易触发）。
+
+公式（**progress 按毫秒计算**，保证精度）：
+
+```
+windowStartMs = (periodStartUnix + windowStartSeconds) * 1000
+windowEndMs   = (periodStartUnix + windowEndSeconds) * 1000
+windowLenMs   = windowEndMs - windowStartMs
+nowMs         = System.currentTimeMillis()
+
+progress = (nowMs - windowStartMs) / windowLenMs
+progress = clamp(progress, 0, 1)
+
+// 比例系数 = progress × (100% - 50%)，即已「消耗」的系数降幅
+// 真正系数 = 100% - 比例系数
+coefficient = 1.0 - progress × (1.0 - 0.5) = 1.0 - 0.5 × progress
+
+effectiveMinSpread = baseSpread × coefficient
+```
+
+**计算示例**（时间区间 14分0秒～15分0秒，窗口 60 秒 = 60000 ms）：
+
+| 时刻       | 进入窗口的毫秒数 | progress（按毫秒） | 比例系数           | 真正系数   |
+|------------|------------------|--------------------|--------------------|------------|
+| 14:00      | 0                | 0/60000 = 0%       | 0% × 50% = 0%      | 100%       |
+| 14:15      | 15000            | 15000/60000 = 25%  | 25% × 50% = 12.5%  | **87.5%**  |
+| 14:30      | 30000            | 30000/60000 = 50%   | 50% × 50% = 25%    | 75%        |
+| 15:00      | 60000            | 60000/60000 = 100%  | 100% × 50% = 50%   | 50%        |
+
+即：在 14分15秒 时，progress = 15000ms / 60000ms = 25%，比例系数 = 12.5%，真正系数 = **87.5%**。实现时统一用毫秒计算 progress，避免秒级舍入误差。
+
+- 需要策略的 `windowStartSeconds`、`windowEndSeconds` 传入计算处；若窗口长度为 0，可退化为系数 = 1.0 或 0.5（需约定）。
+
+**优点**：与「加密价差策略只在窗口内触发」一致，时间语义清晰；毫秒级 progress 更精确。  
+**缺点**：`getAutoMinSpread` 需要增加当前时间（毫秒）和窗口参数（或传整个 strategy）。
+
+---
+
+## 方案二：按「整周期」进度
+
+**区间**：整个周期 `[periodStartUnix, periodStartUnix + intervalSeconds]`。**progress 按毫秒计算**。
+
+```
+periodStartMs = periodStartUnix * 1000
+periodEndMs   = (periodStartUnix + intervalSeconds) * 1000
+periodLenMs   = intervalSeconds * 1000L
+nowMs         = System.currentTimeMillis()
+
+progress = (nowMs - periodStartMs) / periodLenMs
+progress = clamp(progress, 0, 1)
+
+coefficient = 1.0 - 0.5 * progress
+effectiveMinSpread = baseSpread × coefficient
+```
+
+**优点**：只依赖 `intervalSeconds`、`periodStartUnix`、`nowSeconds`，不依赖窗口配置。  
+**缺点**：若窗口只占周期后半段，周期前半段也会在算系数，语义上不如按窗口精确。
+
+---
+
+## 实现要点
+
+### 1. 缓存 100% 基准值
+
+- **BinanceKlineAutoSpreadService**：
+  - `computeAndCache()`：缓存 **不乘 0.7** 的 (avgUp, avgDown)，即 IQR 平均后的原始值（100% 基准）。
+  - 可保留方法名与入参不变，仅去掉 `autoSpreadCoefficient` 的乘法；或新增 `getBaseSpread()` 语义，内部仍用同一缓存。
+
+### 2. 动态系数计算位置
+
+- 系数依赖「当前时间」和「区间定义」，适合在 **触发校验处** 算，而不是在 AutoSpread 服务里写死。
+- **CryptoTailStrategyExecutionService.passMinSpreadCheck()**：
+  - 当前：`getAutoMinSpread(intervalSeconds, periodStartUnix, outcomeIndex)` 得到已乘系数的值。
+  - 改为：  
+    - 取「基础价差」：`getAutoMinSpreadBase(intervalSeconds, periodStartUnix, outcomeIndex)` 或由现有缓存返回 100% 值。  
+    - 在 `passMinSpreadCheck` 内根据 `strategy.windowStartSeconds/windowEndSeconds` 和 `System.currentTimeMillis()`（毫秒）算 `progress`（按毫秒）→ `coefficient` → `effectiveMinSpread = baseSpread × coefficient`。
+
+### 3. 接口形态建议
+
+- **BinanceKlineAutoSpreadService**：
+  - `computeAndCache(interval, periodStartUnix)`：只缓存 100% 基准 (baseUp, baseDown)，不再乘 0.7。
+  - `getAutoMinSpreadBase(interval, periodStartUnix, outcomeIndex): BigDecimal?`：仅返回缓存的基础价差；若需兼容旧名，可保留 `getAutoMinSpread` 但增加可选参数 `coefficient`，默认 1.0。
+- **CryptoTailStrategyExecutionService**：
+  - 在 `passMinSpreadCheck(strategy, periodStartUnix, outcomeIndex)` 内：
+    - 取 `baseSpread = getAutoMinSpreadBase(...)`。
+    - 计算 `progress`（按方案一用 windowStart/End，或方案二用 interval）。
+    - `coefficient = 1.0 - 0.5 * progress`，再 `effectiveMinSpread = baseSpread * coefficient` 做比较。
+
+### 4. 边界与兼容
+
+- 窗口长度为 0：可约定 `coefficient = 0.5` 或 1.0，避免除零。
+- 已有策略未配置窗口（全 0）：若用方案一，可退化为「整周期」或固定 0.5/1.0」。
+- 预加载逻辑（如 CryptoTailOrderbookWsService 的 `precomputeAutoMinSpreadForCurrentPeriods`）无需改，仍调用 `computeAndCache`，只是缓存内容变为 100% 基准。
+
+---
+
+## 小结
+
+| 项目       | 内容 |
+|------------|------|
+| 预加载     | 缓存 100% 基础价差（去掉固定 0.7） |
+| 系数范围   | 100% → 50% 线性递减 |
+| 推荐区间   | 按触发窗口 `windowStartSeconds`～`windowEndSeconds` 计算进度（方案一） |
+| progress   | **按毫秒计算**：`(nowMs - windowStartMs) / windowLenMs`，避免秒级舍入误差 |
+| 计算位置   | 触发时在 `passMinSpreadCheck` 中算 progress → coefficient → effectiveMinSpread |
+
+按上述实现后，AUTO 模式即为「预加载提供 100% 数值 + 随区间时间点从 100% 递减到 50%」的动态方案。

+# Crypto Spread Strategy Configuration Guide
+
+## Part 1: What is Crypto Spread Strategy?
+
+Crypto Spread Strategy is an automated trading strategy designed specifically for Polymarket crypto markets' **5-minute** or **15-minute** "Up or Down" markets.
+
+**Core Logic**: Within a specified time window, when the market price enters your set price range, the system will automatically buy at a fixed price (0.99) without manual operation.
+
+**Use Cases**:
+- You want to capture price fluctuations at the end of market cycles
+- You want to automate trading execution and avoid manual monitoring
+- You have some judgment about market trends and want to set conditions for automatic triggering
+
+---
+
+## Part 2: How the Strategy Works
+
+### 2.1 Basic Flow
+
+```
+Cycle Start → Within Time Window → Price Enters Range → Auto Order
+```
+
+1. **Cycle**: Each market runs on fixed cycles (5 minutes or 15 minutes)
+   - 5-minute market: Every 5 minutes is a cycle (e.g., 10:00, 10:05, 10:10...)
+   - 15-minute market: Every 15 minutes is a cycle (e.g., 10:00, 10:15, 10:30...)
+
+2. **Time Window**: You can set a time period within the cycle
+   - Example: 15-minute market, set window to "3 minutes ~ 12 minutes"
+   - Meaning: Only triggers between the 3rd and 12th minute after cycle start
+
+3. **Price Range**: Set the trigger price range
+   - Example: Minimum price 0.50, Maximum price 0.80
+   - Meaning: Only triggers when market price is between 0.50 ~ 0.80
+
+4. **Auto Order**: After conditions are met, the system automatically buys at price 0.99
+
+### 2.2 Important Limitations
+
+- **Maximum one trigger per cycle**: Within the same cycle, even if conditions are met multiple times, only one order is placed
+- **Fixed order price**: All orders are submitted at price 0.99
+- **Requires separate wallet**: It's recommended to use a dedicated wallet for crypto spread strategies to avoid conflicts with other operations (manual trading, copy trading, etc.)
+
+---
+
+## Part 3: Parameter Details
+
+### 3.1 Basic Parameters
+
+| Parameter | Description | Required | Example |
+|-----------|-------------|----------|---------|
+| **Account** | Select the wallet account for trading | ✅ | Account A |
+| **Strategy Name** | Name your strategy for easy identification | ❌ | "BTC 15min Crypto Spread Strategy" |
+| **Market** | Select the market to trade (5-minute or 15-minute) | ✅ | btc-updown-15m |
+
+### 3.2 Cycle Settings
+
+| Parameter | Description | Required | Example |
+|-----------|-------------|----------|---------|
+| **Cycle Length** | Automatically determined by selected market | ✅ | 15 minutes (900 seconds) |
+| **Time Window Start** | Minutes after cycle start to begin monitoring | ✅ | 3 min 0 sec |
+| **Time Window End** | Minutes after cycle start to stop monitoring | ✅ | 12 min 0 sec |
+
+**Time Window Explanation**:
+- 5-minute market: Can choose any time period within 0 ~ 5 minutes
+- 15-minute market: Can choose any time period within 0 ~ 15 minutes
+- **Start time must ≤ End time**
+- Times outside the window won't trigger even if price conditions are met
+
+**Example**:
+- 15-minute market, window "3 min 0 sec ~ 12 min 0 sec"
+  - 0 ~ 3 minutes after cycle start: Not monitoring
+  - 3 ~ 12 minutes after cycle start: Monitoring price, triggers when conditions met
+  - 12 ~ 15 minutes after cycle start: Not monitoring
+
+### 3.3 Price Range
+
+| Parameter | Description | Required | Range | Example |
+|-----------|-------------|----------|-------|---------|
+| **Minimum Price (minPrice)** | Minimum trigger price | ✅ | 0 ~ 1 | 0.50 |
+| **Maximum Price (maxPrice)** | Maximum trigger price | ❌ | 0 ~ 1, default 1 | 0.80 |
+
+**Price Range Explanation**:
+- Price range is a decimal between 0 ~ 1
+- Only triggers when market price is within [Minimum Price, Maximum Price]
+- If maximum price is not filled, defaults to 1.0 (triggers as long as price ≥ minimum price)
+
+**Example**:
+- Minimum price 0.50, Maximum price 0.80
+  - Price 0.45: Not triggered (below minimum)
+  - Price 0.60: Triggered ✅ (within range)
+  - Price 0.85: Not triggered (above maximum)
+
+### 3.4 Investment Amount
+
+| Parameter | Description | Required | Example |
+|-----------|-------------|----------|---------|
+| **Investment Mode** | Choose ratio or fixed amount | ✅ | Ratio / Fixed Amount |
+| **Ratio (%)** | Percentage of account balance to invest | Conditionally required | 10% (Account has 100 USDC, invest 10 USDC) |
+| **Fixed Amount (USDC)** | Fixed amount to invest each time | Conditionally required | 50 USDC |
+
+**Investment Mode Explanation**:
+
+**Mode 1: By Ratio (RATIO)**
+- Each trigger invests a percentage of current available balance
+- Example: Account has 100 USDC, set ratio to 10%
+  - 1st trigger: Invest 10 USDC
+  - 2nd trigger: If balance becomes 90 USDC, invest 9 USDC
+- **Advantages**: Automatically adapts to account balance changes
+- **Disadvantages**: Investment amount may vary each time
+
+**Mode 2: Fixed Amount (FIXED)**
+- Each trigger invests a fixed specified amount
+- Example: Set fixed amount to 50 USDC
+  - Every trigger invests 50 USDC
+- **Advantages**: Stable investment amount, easy to manage
+- **Disadvantages**: Need to ensure sufficient account balance
+
+**Notes**:
+- Minimum order amount: At least 1 USDC
+- If account balance is insufficient, order will fail and record failure reason
+
+### 3.5 Spread Filter (Advanced Feature)
+
+The spread filter controls whether to trigger based on Binance BTC/USDC K-line volatility. It supports two directions: **Minimum spread** and **Maximum spread**.
+
+| Parameter | Description | Required | Example |
+|-----------|-------------|----------|---------|
+| **Spread Mode** | Choose spread validation method | ✅ | None / Fixed / Auto |
+| **Spread Direction** | Min spread (trigger when ≥) or Max spread (trigger when ≤) | ✅ | Min spread / Max spread |
+| **Spread Value** | Fill when using Fixed mode (unit: USDC) | Conditionally required | 30 |
+
+**Spread Direction**:
+
+- **Min spread**: Triggers only when Binance K-line spread **≥** the set value  
+  - Use when you want to trade only when volatility is "large enough" (avoid entering when volatility is too small).
+- **Max spread**: Triggers only when Binance K-line spread **≤** the set value  
+  - Use when you want to trade only when volatility is "small enough" (avoid entering when volatility is too high).
+
+**Three Spread Modes**:
+
+**Mode 1: None (NONE)**
+- No spread validation
+- Triggers as long as time window and price range conditions are met
+- **Suitable for**: Not concerned about Binance price volatility, only watching Polymarket price
+
+**Mode 2: Fixed (FIXED)**
+- Set a fixed spread value (unit: USDC)
+- **Min spread**: Triggers when K-line spread ≥ set value  
+  - Example: Set 30, spread ≥ 30 → triggered ✅, spread < 30 → not triggered
+- **Max spread**: Triggers when K-line spread ≤ set value  
+  - Example: Set 50, spread ≤ 50 → triggered ✅, spread > 50 → not triggered
+- **Suitable for**: You have a clear spread threshold in mind
+
+**Mode 3: Auto (AUTO)**
+- System automatically calculates an effective spread from the last 20 K-lines
+- Calculation logic:
+  1. Get recent 20 K-lines (matching strategy cycle)
+  2. Filter by direction (Up direction only looks at rising K-lines, Down direction only looks at falling K-lines)
+  3. Remove outliers (using IQR method)
+  4. Calculate average spread × 0.8 as effective spread
+- **Min spread**: Triggers when K-line spread ≥ effective spread  
+- **Max spread**: Triggers when K-line spread ≤ effective spread
+- **Suitable for**: Want automatic adjustment based on historical data without setting a specific value
+
+**Spread Explanation**:
+- Spread = |close price - open price| (Binance BTC/USDC for that K-line)
+- Example: Open price 50000, close price 50030, spread = 30
+- Larger spread means greater price volatility in that cycle
+
+---
+
+## Part 4: Configuration Examples
+
+### Example 1: Simple Strategy (5-minute Market)
+
+**Scenario**: In the last 2 minutes of a 5-minute market, if price is below 0.60, automatically buy 10 USDC
+
+**Configuration**:
+```
+Account: Account A
+Strategy Name: BTC 5min Simple Strategy
+Market: btc-updown-5m
+Time Window: 3 min 0 sec ~ 5 min 0 sec
+Minimum Price: 0.00
+Maximum Price: 0.60
+Investment Mode: Fixed Amount
+Fixed Amount: 10 USDC
+Spread Mode: None
+Enabled: On
+```
+
+**Explanation**:
+- 0 ~ 3 minutes after cycle start: Not monitoring
+- 3 ~ 5 minutes after cycle start: If price ≤ 0.60, automatically buy 10 USDC
+
+---
+
+### Example 2: Ratio Investment Strategy (15-minute Market)
+
+**Scenario**: In the middle segment (5 ~ 10 minutes) of a 15-minute market, if price is between 0.40 ~ 0.70, invest 15% of account balance
+
+**Configuration**:
+```
+Account: Account B
+Strategy Name: BTC 15min Ratio Strategy
+Market: btc-updown-15m
+Time Window: 5 min 0 sec ~ 10 min 0 sec
+Minimum Price: 0.40
+Maximum Price: 0.70
+Investment Mode: By Ratio
+Ratio: 15%
+Spread Mode: None
+Enabled: On
+```
+
+**Explanation**:
+- Assuming account balance is 100 USDC
+- 5 ~ 10 minutes after cycle start: If price is between 0.40 ~ 0.70, automatically buy about 15 USDC (100 × 15%)
+
+---
+
+### Example 3: Strategy with Spread Filter (15-minute Market)
+
+**Scenario**: In the latter segment (10 ~ 14 minutes) of a 15-minute market, if price is between 0.50 ~ 0.80 and Binance spread ≥ 50, invest 20 USDC
+
+**Configuration**:
+```
+Account: Account C
+Strategy Name: BTC 15min Spread Strategy
+Market: btc-updown-15m
+Time Window: 10 min 0 sec ~ 14 min 0 sec
+Minimum Price: 0.50
+Maximum Price: 0.80
+Investment Mode: Fixed Amount
+Fixed Amount: 20 USDC
+Spread Mode: Fixed
+Spread Direction: Min spread
+Spread Value: 50
+Enabled: On
+```
+
+**Explanation**:
+- 10 ~ 14 minutes after cycle start: Only triggers when both conditions are met:
+  1. Price is between 0.50 ~ 0.80 ✅
+  2. Spread direction is "Min spread" and Binance spread ≥ 50 ✅
+- If spread is only 30, won't trigger even if price condition is met
+
+---
+
+### Example 4: Auto Spread Strategy (15-minute Market)
+
+**Scenario**: In the early segment (2 ~ 8 minutes) of a 15-minute market, if price is between 0.30 ~ 0.90, invest 20% of account balance, spread calculated automatically by system
+
+**Configuration**:
+```
+Account: Account D
+Strategy Name: BTC 15min Auto Spread Strategy
+Market: btc-updown-15m
+Time Window: 2 min 0 sec ~ 8 min 0 sec
+Minimum Price: 0.30
+Maximum Price: 0.90
+Investment Mode: By Ratio
+Ratio: 20%
+Spread Mode: Auto
+Spread Direction: Min spread
+Enabled: On
+```
+
+**Explanation**:
+- System automatically calculates effective spread from the last 20 K-lines
+- 2 ~ 8 minutes after cycle start: Only triggers when both conditions are met:
+  1. Price is between 0.30 ~ 0.90 ✅
+  2. Spread direction is "Min spread" and Binance spread ≥ system-calculated effective spread ✅
+
+---
+
+## Part 5: Frequently Asked Questions
+
+### Q1: When will the strategy trigger?
+
+**A**: All of the following conditions must be met simultaneously:
+1. ✅ Current time is within the time window
+2. ✅ Market price is within [Minimum Price, Maximum Price] range
+3. ✅ This cycle hasn't triggered yet (maximum one trigger per cycle)
+4. ✅ If spread filter is set, Binance spread and spread direction must both be satisfied
+
+### Q2: Why didn't my strategy trigger?
+
+**Possible reasons**:
+1. **Time window incorrect**: Current time is not within the set time window
+2. **Price not in range**: Market price is not within [Minimum Price, Maximum Price] range
+3. **Already triggered this cycle**: This cycle has already triggered once, won't trigger again
+4. **Spread not met**: If spread filter is set, Binance spread or spread direction requirement is not satisfied
+5. **Insufficient account balance**: Account balance is less than the set investment amount
+6. **Strategy not enabled**: Check if strategy's enabled status is "On"
+
+### Q3: What does "maximum one trigger per cycle" mean?
+
+**A**: Within each cycle (5 minutes or 15 minutes), even if conditions are met multiple times, only one order is placed.
+
+**Example**:
+- 15-minute market, cycle starts at 10:00
+- At 10:05, price meets condition, triggers order ✅
+- At 10:08, price meets condition again, but won't place another order (already triggered this cycle)
+- At 10:15, new cycle starts, can trigger again
+
+### Q4: What's the difference between fixed amount and ratio?
+
+**Fixed Amount**:
+- Invests the same amount each trigger
+- Example: Set 50 USDC, every trigger is 50 USDC
+- Need to ensure sufficient account balance
+
+**By Ratio**:
+- Invests a percentage of account balance each trigger
+- Example: Set 10%, when account has 100 USDC, invest 10 USDC, after balance becomes 90 USDC, next trigger invests 9 USDC
+- Automatically adapts to balance changes
+
+### Q5: What's the use of the spread filter feature?
+
+**A**: The spread filter decides whether to trigger based on Binance BTC/USDC K-line volatility. It supports two directions.
+
+**Min spread** (trigger when spread **≥** set value):
+- Avoids triggering when volatility is too small
+- Example: Set 30, only triggers when spread ≥ 30
+
+**Max spread** (trigger when spread **≤** set value):
+- Avoids triggering when volatility is too high (lower risk)
+- Example: Set 50, only triggers when spread ≤ 50
+
+**Three mode selection suggestions**:
+- **None**: Not concerned about Binance price volatility, only watching Polymarket price
+- **Fixed**: You know the expected spread threshold (use with Min or Max spread direction)
+- **Auto**: Want effective spread calculated from historical data without setting a specific value
+
+### Q6: Why is it recommended to use a separate wallet?
+
+**A**: To avoid the following issues:
+1. **Balance changes**: If wallet is also used for manual trading, balance changes may affect strategy execution
+2. **Position conflicts**: Manual trading and strategy trading may conflict
+3. **Management confusion**: Difficult to distinguish which orders are from strategy vs manual
+
+**Recommendation**: Create a dedicated wallet, only for crypto spread strategies.
+
+### Q7: Why is the order price fixed at 0.99?
+
+**A**: This is a design feature of the strategy:
+- 0.99 is the highest price in the market (close to 1.0)
+- Buying at the highest price ensures orders execute quickly
+- Although buying price is higher, the strategy's core is capturing market volatility, not pursuing optimal price
+
+### Q8: Does the strategy depend on auto-redeem functionality?
+
+**A**: Yes, crypto spread strategy depends on auto-redeem functionality.
+
+**Reasons**:
+- Strategy orders create positions after execution
+- These positions need to be automatically redeemed after market settlement
+- If auto-redeem is not configured, positions may not be redeemed in time
+
+**Configuration Requirements**:
+- Configure Builder API Key in "System Settings"
+- Enable auto-redeem functionality
+
+---
+
+## Part 6: Important Notes
+
+### 6.1 Account Requirements
+
+- ✅ Account must have API Key, API Secret, API Passphrase configured
+- ✅ Account must have sufficient USDC balance
+- ✅ Recommended to use a dedicated wallet to avoid conflicts with other operations
+
+### 6.2 Time Window Settings
+
+- ⚠️ Start time must ≤ End time
+- ⚠️ Time window cannot exceed cycle length (5-minute market ≤ 5 minutes, 15-minute market ≤ 15 minutes)
+- ⚠️ Recommended to set reasonable time windows, avoid triggering at cycle start or end
+
+### 6.3 Price Range Settings
+
+- ⚠️ Minimum price must ≤ Maximum price
+- ⚠️ Price range is a decimal between 0 ~ 1
+- ⚠️ Recommended to set reasonable price ranges based on market conditions
+
+### 6.4 Investment Amount Settings
+
+- ⚠️ Minimum order amount: At least 1 USDC
+- ⚠️ Ensure sufficient account balance to avoid order failures
+- ⚠️ Ratio mode: Note the impact of account balance changes on investment amount
+
+### 6.5 Spread Filter Settings
+
+- ⚠️ Spread direction: Min spread means "trigger when ≥"; Max spread means "trigger when ≤". Choose according to your need.
+- ⚠️ Fixed mode: Need to fill a reasonable spread value (unit: USDC)
+- ⚠️ Auto mode: System calculates effective spread within the window, no manual value needed
+- ⚠️ Overly strict spread (min spread too high or max spread too low) may make the strategy rarely trigger
+
+### 6.6 Other Notes
+
+- ⚠️ Strategy is enabled by default after creation, can disable "Enabled Status" if need to pause
+- ⚠️ Maximum one trigger per cycle, set trigger conditions reasonably
+- ⚠️ Strategy depends on auto-redeem functionality, ensure Builder API Key is configured
+- ⚠️ Recommended to regularly check trigger records to understand strategy execution

+## 二、策略创建/更新流程（API → 事件）
+
+```mermaid
+sequenceDiagram
+    participant API as Controller
+    participant Svc as CryptoTailStrategyService
+    participant DB as DB
+    participant Event as ApplicationEventPublisher
+
+    API->>Svc: create(request) / update(request)
+    Svc->>Svc: 参数校验（账户、窗口、价格、金额模式等）
+    Svc->>DB: save(entity)
+    Svc->>Event: publishEvent(CryptoTailStrategyChangedEvent)
+    Svc->>API: Result.success(dto)
+```
+
+- **创建**：校验通过后落库，发布 `CryptoTailStrategyChangedEvent`，返回 DTO。
+- **更新**：同上，更新实体后发布同一事件。
+- **删除**：不发布事件（策略已移除，WS 下次刷新订阅时会自然不再包含该策略）。
+
+---
+
+## 三、策略变更后：双路响应
+
+事件发出后，两个监听方并行执行，互不阻塞：
+
+| 监听方 | 动作 | 说明 |
+|--------|------|------|
+| **CryptoTailStrategyScheduler** | `onStrategyChanged` → `runCycle()` 一次 | 用 HTTP 拉订单簿做一轮检查，作为 WS 未就绪时的补充。 |
+| **CryptoTailOrderbookWsService** | `onStrategyChanged` → `refreshAndSubscribe()` | 按当前启用策略重新算 token 列表，向 WS 发送新的 `assets_ids` 订阅。 |
+
+```mermaid
+flowchart LR
+    subgraph 事件
+        E[CryptoTailStrategyChangedEvent]
+    end
+    subgraph 调度器
+        S[Scheduler.onStrategyChanged]
+        R[executionService.runCycle]
+        S --> R
+    end
+    subgraph WS服务
+        W[OrderbookWsService.onStrategyChanged]
+        Ref[refreshAndSubscribe]
+        W --> Ref
+    end
+    E --> S
+    E --> W
+```
+
+---
+
+## 四、WebSocket 订单簿监听流程（主路径）
+
+```mermaid
+flowchart TB
+    subgraph 启动与连接
+        A[PostConstruct init] --> B[connect]
+        B --> C[OkHttp WebSocket 连接 wss://.../ws/market]
+        C --> D[onOpen: refreshAndSubscribe]
+    end
+
+    subgraph 订阅维护
+        D --> E[buildSubscriptionMap]
+        E --> F[遍历 enabled 策略]
+        F --> G[当前周期 periodStartUnix]
+        G --> H[slug = prefix-periodStartUnix]
+        H --> I[Gamma getEventBySlug]
+        I --> J[得到 tokenIds]
+        J --> K[tokenId → List of WsBookEntry]
+        K --> L[发送 type=MARKET, assets_ids=[...]]
+        T[每 25 秒 @Scheduled] --> E
+        EV[onStrategyChanged] --> E
+    end
+
+    subgraph 收消息与触发
+        M[onMessage: book / price_change]
+        M --> N[解析 asset_id, best_bid]
+        N --> O[onBestBid tokenId, bestBid]
+        O --> P[查 tokenToEntries 得到策略列表]
+        P --> Q[筛时间窗内]
+        Q --> R[scope.launch tryTriggerWithPriceFromWs]
+        R --> S[placeOrderForTrigger]
+    end
+
+    L --> M
+```
+
+- **buildSubscriptionMap**：只包含「当前时间仍在窗口内」的策略（`nowSeconds < windowEnd`），并只订阅这些策略对应周期的 token。
+- **onBestBid**：再按当前时间过滤一次时间窗，对每个命中策略在协程里调用 `tryTriggerWithPriceFromWs`，内部会查「本周期是否已触发」和价格区间，通过则 `placeOrderForTrigger`。
+
+---
+
+## 五、执行层：下单条件与顺序（ExecutionService）
+
+无论来自 **runCycle（HTTP）** 还是 **tryTriggerWithPriceFromWs（WS）**，最终都走同一套下单逻辑。
+
+```mermaid
+flowchart TB
+    subgraph runCycle 入口
+        A[runCycle] --> B[findAllByEnabledTrue]
+        B --> C[processStrategy 每个策略]
+        C --> D[在时间窗? 本周期已触发?]
+        D --> E[Gamma getEventBySlug]
+        E --> F[HTTP getOrderbook 两个 token]
+        F --> G[第一个 bestBid 在 minPrice~maxPrice?]
+        G --> H[placeOrderForTrigger]
+    end
+
+    subgraph tryTriggerWithPriceFromWs 入口
+        I[WS onBestBid] --> J[tryTriggerWithPriceFromWs]
+        J --> K[本周期已触发? bestBid 在区间?]
+        K --> H
+    end
+
+    subgraph placeOrderForTrigger 统一
+        H --> L[账户、API 凭证]
+        L --> M[余额、下单金额]
+        M --> N[最优价、数量]
+        N --> O[签名、CLOB 下单]
+        O --> P[保存 CryptoTailStrategyTrigger]
+    end
+```
+
+- **每周期最多触发一次**：由 `triggerRepository.findByStrategyIdAndPeriodStartUnix` 保证。
+- **价格区间**：`minPrice ≤ bestBid ≤ maxPrice` 才触发。
+- **时间窗**：仅当 `windowStart ≤ now < windowEnd`（以当前周期的 `periodStartUnix` 为基准）才参与检查/下单。
+
+---
+
+## 六、关键数据流小结
+
+| 阶段 | 输入 | 输出/动作 |
+|------|------|-----------|
+| 创建/更新策略 | API 请求体 | 落库 + 发布 `CryptoTailStrategyChangedEvent` |
+| 事件 → 调度器 | 事件 | 执行一次 `runCycle()`（HTTP 拉订单簿，满足则下单） |
+| 事件 → WS 服务 | 事件 | `refreshAndSubscribe()`，更新订阅的 `assets_ids` |
+| 定时刷新订阅 | 每 25 秒 | `refreshAndSubscribe()`，保证新周期、新策略被订阅 |
+| WS 收 book/price_change | asset_id, best_bid | `onBestBid` → 时间窗内策略 → `tryTriggerWithPriceFromWs` → 未触发且价格在区间则 `placeOrderForTrigger` |
+| placeOrderForTrigger | 策略、周期、token、outcome、价格 | 账户/余额/价格/签名 → CLOB 下单 → 写触发记录 |
+
+---
+
+## 七、涉及类与职责
+
+| 类 | 职责 |
+|----|------|
+| **CryptoTailStrategyController** | 接收 list/create/update/delete/triggers/marketOptions 的 POST。 |
+| **CryptoTailStrategyService** | 策略 CRUD、校验、发布 `CryptoTailStrategyChangedEvent`。 |
+| **CryptoTailStrategyScheduler** | 监听策略变更事件，执行一次 `runCycle()`。 |
+| **CryptoTailOrderbookWsService** | 连接 CLOB Market WS、维护订阅（事件 + 每 25 秒）、处理 book/price_change、调用 `tryTriggerWithPriceFromWs`。 |
+| **CryptoTailStrategyExecutionService** | `runCycle()`（HTTP 路径）、`tryTriggerWithPriceFromWs()`（WS 路径）、`placeOrderForTrigger()`（统一下单与写触发记录）。 |

+> 前端 UI 与交互详见 `crypto-tail-strategy-ui-spec.md`。
+
+## 1. 数据源
+
+- **Gamma API**：`https://gamma-api.polymarket.com`
+- 用于获取市场元数据：conditionId、开始/结束时间、标题、clobTokenIds 等。
+- 无需鉴权。
+
+## 2. 市场类型与 Slug 规则
+
+| 类型 | Event Slug 规则 | 周期长度 | 说明 |
+|------|-----------------|----------|------|
+| Bitcoin 5 分钟 | `btc-updown-5m-{periodStartUnix}` | 5 min | periodStartUnix 为 5 分钟边界的 Unix 时间戳（秒） |
+| Bitcoin 15 分钟 | `btc-updown-15m-{periodStartUnix}` | 15 min | periodStartUnix 为 15 分钟边界：`(now // 900) * 900` |
+| Ethereum 5 分钟 | `eth-updown-5m-{ts}` | 5 min | 暂未验证是否在平台上线；如有可按相同规则推导 |
+| Ethereum 15 分钟 | `eth-updown-15m-{ts}` | 15 min | 已验证存在 |
+
+- 5 分钟周期：按 **300 秒** 对齐；当前周期起点可用 `(nowUnix // 300) * 300`，下一周期为 `+300`。
+- 15 分钟周期：按 **900 秒** 对齐；当前周期起点可用 `(nowUnix // 900) * 900`。slug 中的时间戳即为周期起始 Unix 秒；周期结束以 API 的 endDate 为准。
+
+## 3. 获取单个周期市场（开始时间、结束时间）
+
+### 3.1 请求
+
+```bash
+# 5 分钟 - 当前周期（示例时间戳需替换为当前周期起点）
+curl -s "https://gamma-api.polymarket.com/events/slug/btc-updown-5m-1771007100"
+
+# 15 分钟 - 需使用实际存在的时间戳（可从前端或历史 slug 得知）
+curl -s "https://gamma-api.polymarket.com/events/slug/btc-updown-15m-1770882300"
+```
+
+### 3.2 响应结构（与开始/结束时间相关）
+
+- **Event 层**：`startDate`、`endDate`（ISO 8601）。
+- **markets[]**：每个市场有 `conditionId`、`question`、`startDate`、`endDate`、`clobTokenIds` 等。
+
+**周期本身**：例如 5 分钟市场 "1:30PM-1:35PM ET"，理应是 **startDate = 1:30 PM**、**endDate = 1:35 PM**。
+
+**API 返回值与周期起止的对应关系（已用脚本验证）**：
+
+| 字段 | 是否等于周期起止 | 说明 |
+|------|------------------|------|
+| **endDate**（Event / Market） | **是**，等于周期结束时间（如 1:35 PM） | API 的 endDate 即周期终点，可直接用。 |
+| **startDate**（Event / Market） | **否**，不等于周期开始时间（1:30 PM） | API 的 startDate 是市场创建/开放时间，不是周期起点，故**不能**当 1:30 PM 用。 |
+
+**正确做法**：周期起点（1:30 PM）用 **slug 中的时间戳** 推导；周期终点（1:35 PM）用 API 的 **endDate**。
+
+- **5 分钟**：周期开始 = `slug_ts`（即 slug 中的 Unix 秒），周期结束 = `endDate`（或 `slug_ts + 300`）。
+- **15 分钟**：周期开始 = `slug_ts`，周期结束 = `endDate`（或 `slug_ts + 900`）。
+
+**示例（脚本输出解读）**：若 current 5m slug 为 `btc-updown-5m-1771007400`、title 为 "1:30PM-1:35PM ET"、endDate 为 `2026-02-13T18:35:00Z`，则 1771007400 = 18:30 UTC = 1:30 PM ET，即周期起点；endDate 18:35 UTC = 1:35 PM ET = 周期终点。next 5m slug 为 1771007700 = 1771007400 + 300，即下一周期起点。15m 同理：current slug 1771007400（1:30–1:45 PM ET），next 1771008300 = 1771007400 + 900（1:45–2:00 PM ET）。
+
+## 4. 如何列出“当前及未来”5/15 分钟市场
+
+- Gamma 未提供按“5 分钟 / 15 分钟”或“Up or Down”的 tag 筛选；`tag_id=744`（cryptocurrency）未返回这些短期市场。
+- **可行方式**：
+  1. **按周期时间戳生成 slug 并逐个请求**  
+     - 5 分钟：当前周期 `ts = (nowUnix // 300) * 300`，下一周期 `ts + 300`，再下一周期 `ts + 600` …  
+     - 15 分钟：`ts = (nowUnix // 900) * 900`，然后 `ts + 900`、`ts + 1800` …  
+     - 请求 `GET /events/slug/btc-updown-5m-{ts}` 或 `btc-updown-15m-{ts}`；若返回 404 表示该周期尚未创建或已过期，可跳过。
+  2. **用户选择“市场”时**：若前端/后端已知“系列”（如 Bitcoin 5 minute），则只需约定 slug 前缀（`btc-updown-5m`、`btc-updown-15m`）与周期长度（300/900），按当前时间计算周期起点并请求对应 slug 即可得到当前周期的 conditionId、startDate、endDate；下一周期同理。
+
+## 5. 周期边界与“每周期监听”
+
+- **周期开始**：使用 **slug 中的时间戳** `periodStartUnix`（即请求 slug 时的 `btc-updown-5m-{ts}` 里的 `ts`），不要用 API 返回的 startDate。
+- **周期结束**：使用 API 返回的 **event.endDate 或 market.endDate**（与 slug_ts + 300/900 一致）。
+- 判断“当前是否在该周期内”：`periodStartUnix <= nowUnix < endDateUnix`，其中 `periodStartUnix` 从 slug 得到，`endDateUnix` 由 endDate 解析。
+- 策略“每周期开始时开始监听”：当 `now` 跨过当前周期的 endDate（或下一周期的 periodStartUnix）时，视为新周期开始，重置“本周期是否已触发”等状态。
+
+## 6. 如何保证每个周期的市场都能正确处理
+
+### 6.1 用“当前时间”唯一确定当前周期
+
+- 服务端只用**当前 Unix 时间**推导周期，不依赖 API 的 startDate。
+- **5 分钟**：`periodStartUnix = (nowUnix / 300) * 300`（整除）。
+- **15 分钟**：`periodStartUnix = (nowUnix / 900) * 900`。
+- 同一时刻算出的 `periodStartUnix` 唯一，对应唯一 slug（如 `btc-updown-5m-{periodStartUnix}`），从而对应唯一市场（conditionId、tokenIds、endDate）。
+
+### 6.2 按周期拉取市场并切换
+
+- **首次进入或策略启用**：用当前的 `periodStartUnix` 拼 slug，请求 Gamma `GET /events/slug/{slug}`，拿到该周期的 conditionId、endDate、clobTokenIds；用 endDate 解析得到 `endDateUnix`。
+- **每次需要判断“是否还在本周期”或“是否该下单”时**：先算当前 `currentPeriodStart = (nowUnix / interval) * interval`（interval 为 300 或 900）。若 `currentPeriodStart` 大于上一笔使用的 `periodStartUnix`，说明已进入**下一周期**：
+  - 用新的 `currentPeriodStart` 拼 slug，重新请求 Gamma，拿到**新周期**的 conditionId、endDate、clobTokenIds；
+  - 用新周期的 tokenIds 订阅/拉取订单簿，用新 endDate 作为本周期结束时间；
+  - 重置本周期“是否已触发”等状态，避免把上一周期的状态带到新周期。
+- **周期内**：始终用**本周期**的 conditionId、tokenIds、endDate 做价格监听与下单，不要混用上一周期的数据。
+
+### 6.3 周期切换时机与 404 处理
+
+- **切换时机**：以 `nowUnix >= endDateUnix` 或 `(nowUnix / interval) * interval > periodStartUnix` 作为“本周期已结束”，立刻按 6.2 用新 `periodStartUnix` 拉新周期市场。
+- **新周期市场尚未创建（404）**：Gamma 可能稍晚才创建下一周期 event。若请求 slug 返回 404，可短间隔重试（如 5–15 秒）或等到下一整点/对齐点再试；重试时仍用**同一** `periodStartUnix`，避免用错周期。若长时间 404，可记录日志并跳过该周期，下一周期再正常拉取。
+
+### 6.4 下单失败重试规则（每周期最多下单一次）
+
+- 市价单提交失败时，**最多重试 2 次**（即 1 次初始 + 2 次重试，共 3 次尝试）。
+- 若 3 次均失败：
+  - 本周期**不再**对该 outcome 下单；
+  - 记录失败原因与状态（便于审计与前端展示触发记录）。
+- 周期切换时（6.2）重置为“未下单”，仅对新周期做新的判断与尝试。
+
+### 6.5 去重与幂等（每周期最多触发一次）
+
+- 以「策略 + 周期」唯一标识一次执行，例如 `(strategyId, periodStartUnix)` 或 `(accountId, slugPrefix, periodStartUnix)`。
+- 在数据库或内存中记录：本周期是否已触发、是否已下单。若已触发，同一周期内不再根据价格区间下单。
+- 周期切换时（6.2）清空或更新为“新周期未触发”，只对新周期的 conditionId/tokenIds 做监听与下单。
+
+### 6.6 时间区间（窗口）内才触发
+
+- 策略可配置**时间区间**：从周期起点起算的「开始秒数」与「结束秒数」，例如 5 分钟市场可选 0～300 秒内的一段，15 分钟市场可选 0～900 秒内的一段（对应前端“分+秒”下拉，如 3 分 0 秒～12 分 0 秒即 180～720 秒）。
+- **执行规则**：仅当 `periodStartUnix + windowStartSeconds <= nowUnix < periodStartUnix + windowEndSeconds` 时，才根据 7.1 判断价格是否进入 [minPrice, maxPrice] 并执行下单；**区间外不进行价格判断与下单**。
+- 存储：策略表（或配置）中保存 `windowStartSeconds`、`windowEndSeconds`（整数，单位秒）；校验：`windowStartSeconds <= windowEndSeconds`，且不超过周期长度（5min 市场 ≤ 300，15min 市场 ≤ 900）。详见 [UI 规格 - 时间区间](crypto-tail-strategy-ui-spec.md)。
+
+### 6.7 小结
+
+| 要点 | 做法 |
+|------|------|
+| 周期唯一性 | 用 `(nowUnix / interval) * interval` 得到 periodStartUnix，再拼 slug，不依赖 API startDate。 |
+| 周期数据 | 每周期用**该周期**的 slug 请求 Gamma，使用返回的 conditionId、endDate、clobTokenIds。 |
+| 切换 | 当 `nowUnix >= endDateUnix` 或当前算出的 periodStartUnix 变化时，拉取新周期并重置状态。 |
+| 404 | 同一 periodStartUnix 重试；长时间 404 可跳过该周期并打日志。 |
+| 下单失败 | 失败后最多重试 2 次；仍失败则本周期不再下单并记录状态。 |
+| 每周期只触发一次 | 用 (策略, periodStartUnix) 做去重，周期切换时重置“已触发”状态。 |
+| 时间区间 | 仅当 periodStartUnix + windowStartSeconds ≤ now < periodStartUnix + windowEndSeconds 时做价格判断与下单；区间外不处理。 |
+
+按上述方式，每个周期都会对应到正确的 slug、正确的市场与 endDate，并在周期结束时切换到下一周期；仅在配置的时间窗口内才根据价格触发下单，避免混周期或漏周期。
+
+## 7. 与订单簿 / 价格的关系
+
+- 价格由 **CLOB 订单簿**（或 WebSocket）获取，不依赖 Gamma；Gamma 仅提供市场元数据。
+- 使用 market.conditionId 与 markets[].clobTokenIds 解析出 tokenId，再订阅或请求该 token 的订单簿即可得到实时价格，用于区间判断与市价下单。
+
+### 7.1 价格区间与「反方向」判断（如 minPrice = 0.92）
+
+二元市场（Up or Down）有两个 outcome：通常 outcomeIndex 0 = Up，1 = Down，各对应一个 tokenId 和订单簿。
+
+- **配置含义**：用户配置 minPrice = 0.92（及可选 maxPrice，默认 1）表示「当**某个 outcome 的价格**落在 [0.92, 1] 时触发市价买入**该** outcome」。
+- **不预先选方向**：不需要用户选「买 Up 还是买 Down」；谁的价格先进入区间就买谁。
+- **订单簿取价方式（与现有市价单逻辑一致）**：
+  - 对每个 outcome，取该 tokenId 订单簿的 **bestBid**（最高买入价）作为当前价格用于区间判断；若取价规则与现有市价买入逻辑不同，请以系统现有规则为准并在实现文档中写明。
+- **判断方式**：
+  - 同时取**两个 outcome** 的当前价格（按上述取价规则）。
+  - 对 **outcome 0**：若 `price0 >= minPrice && price0 <= maxPrice` → 满足触发条件，买入 outcome 0（Up）。
+  - 对 **outcome 1**：若 `price1 >= minPrice && price1 <= maxPrice` → 满足触发条件，买入 outcome 1（Down）。
+- **反方向**：「反方向」即另一个 outcome。例如若本轮已因 outcome 0 进入 [0.92, 1] 而买入 Up，则本周期内**不再**检查 outcome 1 是否也进入区间、也不再买 Down；反之若先触发的是 outcome 1（Down），则本周期不再买 Up。实现上：一旦本周期已对**任意一个** outcome 触发并下单，即标记本周期已触发，不再对**另一个 outcome（反方向）**做区间判断与下单。
+- **同一时刻两边都进区间**：若同一时刻 Up 和 Down 的价格都在 [0.92, 1]（理论上二元市场 Up+Down≈1 时不会同时 ≥0.92，但若出现），可约定按 outcomeIndex 优先（如先判 0 再判 1）或先到先得，只执行一笔买入，本周期不再买反方向。
+
+总结：配置 0.92 时，对**两个方向**都做同一区间判断；先满足区间的那一侧触发买入，另一侧即为反方向，本周期不再触发。
+
+## 8. 验证方式
+
+**startDate/endDate 验证结论**：已用脚本对比 slug 时间戳与 API 返回的 startDate/endDate。**endDate 等于当前周期结束时间**；**startDate 不等于周期起始点**（为市场创建/开放时间），周期起始点应以 slug 中的时间戳为准。详见上文 3.2、5 节。
+
+### 8.1 脚本（推荐）
+
+项目内脚本，会请求当前/下一 5 分钟与 15 分钟 BTC 市场并打印 conditionId、startDate、endDate、clobTokenIds：
+
+```bash
+python3 scripts/fetch_crypto_minute_markets.py
+```
+
+### 8.2 curl 示例
+
+```bash
+# 5 分钟 - 当前或下一周期（时间戳需替换为实际周期起点）
+curl -s "https://gamma-api.polymarket.com/events/slug/btc-updown-5m-1771007100"

+# 加密价差策略 - 最小价差参数流程分析
+
+## 一、需求摘要
+
+在现有加密价差策略上增加**最小价差**参数：当策略条件（时间窗、价格区间）满足时，再判断**当前周期 Binance K 线的开盘价与收盘价价差**是否满足最小价差；满足才下单，不满足则等待，直到价差满足再下单。
+
+- **后端**：需订阅币安对应币对（如 BTC/USDC）的 K 线，维护当前周期的**开盘价**与**实时收盘价**，并在触发时做价差校验。
+- **前端**：可配置三种场景——无、固定、自动（见下）。
+
+---
+
+## 二、前端配置场景
+
+| 场景 | 配置方式 | 校验逻辑 |
+|------|----------|----------|
+| **无** | 不进行价差校验 | 与现有一致：仅判断时间窗 + 价格区间，满足即下单。 |
+| **固定** | 用户输入一个固定价差（如 30） | 当 \|收盘价 − 开盘价\| ≥ 该固定值时，校验通过，再下单。 |
+| **自动** | 由系统根据历史数据计算最小价差 | 见下文「自动模式计算逻辑」；得到数值后，后续与固定模式一致：\|收盘价 − 开盘价\| ≥ 计算值 则通过。 |
+
+### 自动模式计算逻辑
+
+- 通过币安 API 获取**历史 20 根** K 线（与策略周期一致：5m 取 5m K 线，15m 取 15m K 线）。
+- **下单方向 = Down**（outcomeIndex = 1）：只取「收盘价 < 开盘价」的 K 线，得到价差序列（开盘价 − 收盘价）。
+- **下单方向 = Up**（outcomeIndex = 0）：只取「收盘价 > 开盘价」的 K 线，得到价差序列（收盘价 − 开盘价）。
+- **异常值剔除**：对上述价差序列做异常值过滤（见下文「异常值剔除」），再用**剩余样本**求平均价差，乘以系数 **80%** 得到最小价差；后续用该值做 \|收盘价 − 开盘价\| ≥ 该值 的校验。
+- **历史数据获取时机**：**在该周期开始时就拉取并计算**，不在保存策略时计算。订单簿 WS 在周期开始时刷新订阅（含每 25 秒或周期切换时的 refreshAndSubscribe），此时对当前周期内所有启用且为 AUTO 的策略，按 (intervalSeconds, periodStartUnix) 预拉该周期前 20 根已收盘 K 线并计算 minSpreadUp/minSpreadDown 写入缓存；该周期内触发时直接用缓存，无需在触发时再调 REST。
+
+### 异常值剔除
+
+- **目的**：避免少数极端 K 线（如 14 组价差在 50 以内、1 组价差 200）拉高平均价差，导致最小价差偏大、难以触发。
+- **做法**：在按方向得到价差序列后，先**剔除异常值**，再对剩余价差求平均并 × 0.8。
+- **推荐方法：IQR（四分位距）**
+  - 对价差序列排序，计算 Q1（25% 分位）、Q3（75% 分位）、IQR = Q3 − Q1。
+  - 保留区间 **[Q1 − 1.5×IQR, Q3 + 1.5×IQR]** 内的价差，剔除该区间外的点。
+  - 示例：15 组价差，14 组在 50 以内、1 组为 200 → 200 会超出上界被剔除，只用 14 组参与平均。
+- **边界与降级**
+  - 若剔除后剩余样本数过少（如 &lt; 3），则**不剔除**：用全部价差样本求平均 × 0.8。
+  - 若无满足方向的 K 线（如 20 根里没有 close &lt; open），仍按原文档降级处理（全量 \|close−open\| 或返回 0）。

+└─────────────────────────────────────────────────────────────────────────────────┘
+```
+
+- **「等待价差满足」**：不主动轮询；下次 CLOB 订单簿或币安 K 线有推送时，会再次进入上述判断，此时 close 可能已更新，价差可能已满足，再决定是否下单。
+- **每周期最多触发一次**：仍由现有「本周期是否已触发」保证；价差不满足时**不写触发记录**，也不占「已触发」名额，直到某次检查同时满足价格区间与价差后才下单并标记已触发。
+
+---
+
+## 四、自动模式：何时拉历史、如何算、如何用
+
+- **何时拉 20 根历史 K 线并计算**  
+  - **在该周期开始时就预计算**，不在保存策略时计算。  
+  - 订单簿 WS 在**周期开始时**会刷新订阅（`refreshAndSubscribe`：每 25 秒或检测到周期切换时），此时对当前周期内所有启用且 minSpreadMode=AUTO 的策略，按 `(intervalSeconds, periodStartUnix)` 异步拉取该周期前 20 根已收盘 K 线（REST `endTime = periodStartUnix * 1000`），按 Up/Down 分别算 avgSpread × 0.8（含 IQR 剔除）并写入缓存。该周期内后续触发时直接用缓存，**不在触发时再调 REST**。  
+  - 若某周期未做预计算（如服务刚启动且尚未到刷新时机），触发时仍会按需调用 `computeAndCache` 并缓存，保证逻辑正确。  
+  - 前端「自动最小价差」接口仅作**预览**，实际下单校验不依赖该接口。
+
+- **计算细节**  
+  - 历史 20 根：币安 REST `GET /api/v3/klines?symbol=BTCUSDC&interval=5m|15m&limit=20`（或 21 取前 20 根已收盘），每根格式为 [openTime, open, high, low, close, ...]。  
+  - **Down（outcomeIndex=1）**：筛选 close < open，价差 = open − close，得到价差序列 → **异常值剔除（IQR）** → 对剩余价差求平均，再 × 0.8 → minSpreadDown。  
+  - **Up（outcomeIndex=0）**：筛选 close > open，价差 = close − open，得到价差序列 → **异常值剔除（IQR）** → 对剩余价差求平均，再 × 0.8 → minSpreadUp。  
+  - **异常值剔除**：见上文「异常值剔除」；剔除后再平均。若剔除后剩余样本 &lt; 3，则不剔除，用全部价差样本求平均。  
+  - 若无满足方向的 K 线（例如 20 根里没有一根 close < open），可降级：用全部 20 根的 |close−open| 平均 × 0.8，或返回 0/不校验，具体产品可定。
+
+- **触发时使用**  
+  - 当前要下单的是 outcomeIndex（0=Up, 1=Down），取对应的 minSpreadUp 或 minSpreadDown 作为 effectiveMinSpread，再与 |close − open| 比较。
+
+---
+
+## 五、后端模块与数据流
+
+| 模块 | 职责 |
+|------|------|
+| **BinanceKlineService（新）** | 1）订阅币安 WS：BTCUSDC 的 5m、15m K 线流（可按需只订阅有策略使用的周期）。<br>2）维护「当前周期」数据：以 periodStartUnix（或 K 线 t 对齐）为 key，存 (open, close)；K 线 WS 推送时更新 close，新周期首条推送时更新 open。<br>3）提供 getCurrentOpenClose(symbol, intervalSeconds, periodStartUnix) → (open, close)?，供执行层价差校验使用。 |
+| **BinanceKlineAutoSpreadService 或合入上者（新）** | 1）按**周期**拉取：以 periodStartUnix 为界，REST 拉取该周期前的 20 根已收盘 K 线。<br>2）按 Up/Down 得到价差序列 → **IQR 异常值剔除** → 对剩余价差求平均 × 0.8，缓存 (intervalSeconds, periodStartUnix) → (minSpreadUp, minSpreadDown)。<br>3）提供 getAutoMinSpread(intervalSeconds, periodStartUnix, outcomeIndex) 与 computeAndCache(intervalSeconds, periodStartUnix)。**周期开始时**由 CryptoTailOrderbookWsService 在 refreshAndSubscribe 后对当前周期内 AUTO 策略预调 computeAndCache；触发时直接用缓存，未命中时再按需计算。 |
+| **CryptoTailStrategy（实体）** | 新增字段建议：minSpreadMode（NONE/FIXED/AUTO）、minSpreadValue（固定时使用；AUTO 时可为空或存上次计算值用于展示）。 |
+| **CryptoTailStrategyExecutionService（现有）** | 在 tryTriggerWithPriceFromWs 与 runCycle 分支中，在调用 placeOrderForTrigger 前：若 minSpreadMode != NONE，则取 open/close 与 effectiveMinSpread，校验 \|close−open\| >= effectiveMinSpread；不通过则 return，不调用 placeOrderForTrigger。 |
+| **CryptoTailOrderbookWsService（现有）** | 仍只根据 CLOB bestBid 触发；价差校验在执行层统一做。**新增**：refreshAndSubscribe 完成后，对当前周期内所有启用且 minSpreadMode=AUTO 的策略，异步调用 BinanceKlineAutoSpreadService.computeAndCache，在周期开始即预计算最小价差。 |
+
+- **币安 K 线与周期对齐**  
+  - 策略周期：periodStartUnix 为秒（如 5m 周期 = 300 的倍数，15m = 900 的倍数）。  
+  - 币安 K 线：t 为毫秒，同一周期：t_ms = periodStartUnix * 1000。  
+  - 用 (intervalSeconds, periodStartUnix) 或 (interval, t_ms) 对齐即可从 BinanceKlineService 取到「当前周期」的 open 和实时 close。
+
+---
+
+## 六、固定（FIXED）与自动（AUTO）时序图
+
+### 6.1 固定（FIXED）时序图
+
+固定模式：用户保存策略时写入 `minSpreadValue`（如 30）；触发时直接用该值与当前周期 \|close−open\| 比较，不拉历史 K 线。

+    Exec->>Exec: 价差校验 → 通过则下单（或本周期已触发则跳过）
+```
+
+---
+
+## 七、流程小结（按执行顺序）
+
+1. **策略配置**  
+   - 用户选择：无 / 固定（输入数值）/ 自动。  
+   - 固定：必填 minSpreadValue，保存到 DB。  
+   - 自动：不填 minSpreadValue，**不在保存时计算**；按周期在首次需要时计算并缓存。
+
+2. **运行时**  
+   - 币安 WS 持续更新当前周期的 (open, close)。  
+   - CLOB 订单簿（或 HTTP）带来 bestBid；若时间窗 + 价格区间 + 本周期未触发 均满足：  
+     - 若 minSpreadMode == NONE → 直接 placeOrderForTrigger。  
+     - 否则取当前周期 open/close 与 effectiveMinSpread（固定值或自动缓存值），若 \|close−open\| >= effectiveMinSpread → placeOrderForTrigger；否则本轮不下单，等后续推送再判。
+
+3. **下单与去重**  
+   - 仍保持「每周期最多触发一次」；价差不满足时不写触发记录，直到某次同时满足价格与价差后才下单并写记录。
+
+按上述流程即可在现有加密价差策略上接入「最小价差」参数，并由后端订阅币安 K 线、在触发前做价差校验；固定与自动的时序差异见**第六节时序图**。

+> 周期推导与市场数据获取详见 `crypto-tail-strategy-market-data.md`。
+
+与现有跟单/回测保持同一风格（Ant Design、响应式、多语言），以下为页面结构及所含元素。
+
+---
+
+## 1. 导航与路由
+
+| 项目 | 说明 |
+|------|------|
+| **菜单** | 在「跟单管理」同级或其下增加一项，如「加密价差策略」，key 建议 `/crypto-tail-strategy`。 |
+| **路由** | 列表页 `/crypto-tail-strategy`；可选详情/触发记录 `/crypto-tail-strategy/records/:id`。 |
+
+参考：`Layout.tsx` 中 `/copy-trading`、`/backtest` 的配置；`App.tsx` 中对应 `Route`。
+
+---
+
+## 2. 列表页（主页面）
+
+**路径**：`/crypto-tail-strategy`  
+**组件**：如 `CryptoTailStrategyList.tsx`（或 `TailStrategyList.tsx`）。
+
+### 2.1 顶部操作区
+
+| 元素 | 类型 | 说明 |
+|------|------|------|
+| 页面标题 | 标题文案 | 如「加密价差策略」，用 `t('cryptoTailStrategy.list.title')`。 |
+| **钱包使用提示** | **Alert（Warning）** | **必须**在页面顶部或标题下方展示：提示用户**使用单独/专用钱包**运行本策略，避免该钱包用于手动交易、跟单等其他操作，否则可能导致余额或仓位变化，进而造成策略执行异常（如余额不足、下单失败等）。文案走多语言 `t('cryptoTailStrategy.list.walletTip')`，可带 `showIcon`。 |
+| 新增策略 | Button（Primary） | 点击时**先检查自动赎回相关配置**（见 2.4）；若未配置则弹出「去配置」简易弹窗，若已配置则打开「新增策略」表单弹窗。图标可用 `PlusOutlined`。 |
+| 筛选（可选） | Select / 筛选项 | 按账户、启用状态筛选；移动端可收起到抽屉或折叠。 |
+
+### 2.2 列表内容（桌面端：Table，移动端：Card 列表）
+
+| 列/卡片项 | 说明 |
+|-----------|------|
+| 策略名称 | 用户填的配置名或自动生成名。 |
+| 关联市场 | 展示市场标题 + 周期，如「Bitcoin Up or Down - 5 minute」。 |
+| 时间区间 | 如「3 分 0 秒 ~ 12 分 0 秒」（与周期类型一致：5min 为 0–5 分，15min 为 0–15 分）。 |
+| 价格区间 | 如 `[0.92, 1]` 或「0.92 ~ 1」（maxPrice 为空时显示为 1）。 |
+| 投入方式 | 「比例 10%」或「固定 100 USDC」，用 `formatUSDC` 格式化金额。 |
+| 状态 | Tag 或 Switch：启用 / 停用。 |
+| 最近触发 | 最近一次触发时间（若有）；无则「-」。 |
+| 操作 | 编辑、启用/停用、删除、查看触发记录。删除前 Popconfirm 二次确认。 |
+
+### 2.3 与现有风格对齐
+
+- 加载态：`Spin` 包裹列表。
+- 空状态：无数据时展示空状态插画 + 引导「新增策略」。
+- 响应式：`useMediaQuery({ maxWidth: 768 })`，桌面用 Table，移动用 Card + 操作折叠/抽屉。
+
+参考：`CopyTradingList.tsx` 的 Table 列、Card 布局、筛选与 Modal 打开方式。
+
+### 2.4 创建前检查：自动赎回配置（必须）
+
+策略依赖**自动赎回**（需通过 Relayer/Builder API 提交链上赎回）。用户点击「新增策略」时：
+
+1. **检查**：请求系统配置（如 `apiService.systemConfig.getConfig()` 或已有接口），判断是否已配置 Builder API Key（及可选：自动赎回已开启）。若 `builderApiKeyConfigured === false`（或后端约定之「未配置」状态），视为未配置。
+2. **未配置时**：不打开新增策略表单，改为弹出**简易弹窗**（Modal），内容建议：
+   - **标题**：如「请先配置自动赎回」，`t('cryptoTailStrategy.redeemRequiredModal.title')`。
+   - **正文**：简短说明加密价差策略依赖自动赎回，需要先在「系统设置」中配置 Builder API Key 及自动赎回。文案 `t('cryptoTailStrategy.redeemRequiredModal.description')`。
+   - **操作**：
+     - **去配置**：主按钮，点击后关闭弹窗并跳转到系统设置页（如 `/system-settings`，该页含 Relayer 配置与自动赎回开关）。
+     - **取消**：次按钮或关闭图标，仅关闭弹窗。
+3. **已配置时**：正常打开新增策略表单弹窗。
+
+弹窗保持简易，无需表单，仅提示 + 跳转；多语言键示例：`cryptoTailStrategy.redeemRequiredModal.title`、`cryptoTailStrategy.redeemRequiredModal.description`、`cryptoTailStrategy.redeemRequiredModal.goToSettings`、`cryptoTailStrategy.redeemRequiredModal.cancel`。
+
+---
+
+## 3. 新增 / 编辑策略弹窗（Modal）
+
+**组件**：如 `CryptoTailStrategyFormModal.tsx` 或内嵌在列表页的 Modal。
+
+### 3.1 表单字段
+
+| 表单项 | 类型 | 必填 | 说明 |
+|--------|------|------|------|
+| **钱包提示（简短）** | **Alert（Warning）** | - | 在「选择账户」上方或表单单列顶部展示简短提示：建议使用**专用钱包**，避免手动操作等导致异常。文案如 `t('cryptoTailStrategy.form.walletTip')`。 |
+| 策略名称 | Input | 否 | 用于列表展示，可占位「自动生成」。 |
+| 选择账户 | Select | 是 | 下拉已导入账户（与跟单一致，来自 `useAccountStore()` 或接口）。 |
+| 选择市场 | 市场选择器 | 是 | 仅展示 5/15 分钟加密市场；支持搜索；展示市场标题 + 周期（5min/15min）；一个策略绑一个市场。 |
+| **时间区间** | **开始 / 结束** | 是 | 仅在本周期内的该时间窗口内，价格满足时才下单；区间外不处理。见下方说明。 |
+| 区间开始 | 下拉（分 + 秒） | 是 | 从周期起点起算的「开始」偏移。5 分钟市场可选 0～5 分 + 0～59 秒（总不超过 5 分钟）；15 分钟市场可选 0～15 分 + 0～59 秒（总不超过 15 分钟）。 |
+| 区间结束 | 下拉（分 + 秒） | 是 | 从周期起点起算的「结束」偏移。范围同上，且**区间开始不得大于区间结束**（前端校验）。 |
+| 最低价 minPrice | InputNumber | 是 | 0～1，精度 2～4 位小数；校验 minPrice ≤ 1。 |
+| 最高价 maxPrice | InputNumber | 否 | 0～1，占位「不填默认为 1」；若填则校验 minPrice ≤ maxPrice ≤ 1。 |
+| 投入方式 | Radio.Group | 是 | 选项：「按比例」「固定金额」。 |
+| 比例 % | InputNumber | 条件必填 | 选「按比例」时显示；0～100；可展示当前账户 USDC 余额与预估金额。 |
+| 固定金额 (USDC) | InputNumber | 条件必填 | 选「固定金额」时显示；≥ 最小下单额，≤ 账户余额；用 `formatUSDC` 展示。 |
+| 启用状态 | Switch | 否 | 新增默认开启；编辑可切换。 |
+
+**时间区间说明**：例如 15 分钟市场配置「3 分 0 秒」～「12 分 0 秒」，表示从周期开始后第 3 分钟到第 12 分钟之间，若价格进入 [minPrice, maxPrice] 才下单；第 0～3 分钟、第 12～15 分钟即使价格满足也不下单。5 分钟市场同理，可选 0～5 分钟内的一段（如 0～2、2～5）。前端用下拉选择「分钟」+「秒」，后端存为相对周期起点的秒数（如 windowStartSeconds、windowEndSeconds）。
+
+### 3.2 校验与提交
+
+- 提交前：市场为 5/15 分钟、**时间区间开始 ≤ 时间区间结束**、时间区间不超出周期长度（5min 市场结束 ≤ 5 分 0 秒，15min 市场结束 ≤ 15 分 0 秒）、minPrice 合法、maxPrice 若填则 ≥ minPrice、余额/比例合法。
+- 提交后：关闭弹窗、刷新列表、`message.success`；失败在表单上展示接口错误信息。
+
+参考：`CopyTradingOrders/AddModal.tsx` 的 Form 布局、`Form.Item` + `rules`、条件显示（比例/固定金额）。
+
+---
+
+## 4. 触发记录
+
+**入口**：列表行操作「查看触发记录」或单独 Tab/页。
+
+### 4.1 展示方式（二选一或并存）
+
+- **弹窗**：Modal 内 Table，按策略 ID 拉取该策略的触发记录。
+- **独立页**：路由如 `/crypto-tail-strategy/records/:strategyId`，页面内 Table 或 Card 列表。
+
+### 4.2 记录列表字段

+| 方向 (outcome) | Up / Down。 |
+| 触发价格 | 当时进入区间的价格。 |
+| 投入金额 | USDC，用 `formatUSDC`。 |
+| 订单 ID | 若有；可截断 + Tooltip 全量。 |
+| 状态 | 成功 / 失败。 |
+
+支持按时间范围、状态筛选；移动端用 Card 或折叠列表。
+

+
+## 5. 组件与技术要点
+
+| 要点 | 说明 |
+|------|------|
+| **钱包提示** | 列表页与新增/编辑表单**必须**包含「使用单独钱包」的 Alert 提示，避免用户用混用钱包导致异常；文案走多语言。 |

+| 多语言 | 所有文案 `t('cryptoTailStrategy.xxx')`，在 `locales/zh-CN`、`zh-TW`、`en` 的 `common.json` 中增加键。需包含：`cryptoTailStrategy.list.walletTip`、`cryptoTailStrategy.form.walletTip`，以及 `cryptoTailStrategy.redeemRequiredModal.title`、`cryptoTailStrategy.redeemRequiredModal.description`、`cryptoTailStrategy.redeemRequiredModal.goToSettings`、`cryptoTailStrategy.redeemRequiredModal.cancel`。文案示例：列表页 `walletTip`：「请使用单独的钱包运行加密价差策略，避免该钱包用于手动交易、跟单等其他操作，否则可能导致余额或仓位变化，造成策略执行异常。」表单内 `walletTip`：「建议使用专用钱包，避免手动操作等导致余额或下单异常。」未配置赎回弹窗 `title`：「请先配置自动赎回」；`description`：「加密价差策略依赖自动赎回功能，请先在系统设置中配置 Builder API Key 并开启自动赎回。」；`goToSettings`：「去配置」；`cancel`：「取消」。 |
+| 金额 | 统一 `formatUSDC`（见 frontend.mdc）。 |
+| 响应式 | `useMediaQuery`；按钮触摸目标 ≥ 44px；移动端主操作突出。 |
+| 类型 | 不用 `any`；为策略、触发记录定义 TypeScript 类型。 |
+| API | 通过 `apiService` 封装（如 `apiService.cryptoTailStrategy.list/create/update/delete/records`）。 |
+

+
+---
+
+## 7. 小结：UI 包含的主要元素
+
+- **导航**：主导航中「加密价差策略」入口。
+- **列表页**：标题、钱包提示 Alert、新增按钮（点击前先检查赎回配置，未配置则弹「去配置」简易弹窗）、筛选、表格/卡片（策略名、市场、价格区间、投入方式、状态、最近触发、操作）、加载与空状态。
+- **未配置赎回弹窗**：简易 Modal，提示依赖自动赎回、需先配置 Builder API Key 与自动赎回；按钮「去配置」（跳转 `/system-settings`）、「取消」。
+- **表单弹窗**：策略名、账户、市场选择、minPrice/maxPrice、投入方式（比例/固定）、启用开关、提交/取消。
+- **触发记录**：时间、市场、outcome、触发价格、金额、订单 ID、状态；支持弹窗或独立页。
+- **通用**：Ant Design 组件、响应式、多语言、formatUSDC、TypeScript 类型。
+
+---
+
+## 附录 A 后端/产品要求：自动赎回须支持本策略仓位
+
+自动赎回逻辑**必须支持赎回由加密价差策略产生的订单所对应的仓位**。即：本策略触发的市价买入会形成仓位，这些仓位在满足「可赎回」条件时，应被纳入现有自动赎回流程并正常发起赎回，不得因来源为「加密价差策略」而被排除。后端实现时需保证：
+
+- 加密价差策略下单产生的仓位，与跟单/手动下单等来源的仓位一视同仁，参与可赎回查询与批量赎回；
+- 若当前自动赎回按账户或仓位类型过滤，需将「加密价差策略订单产生的仓位」包含在内。
+
+这样前端所依赖的「自动赎回」对该策略才完整有效。

+# 加密价差策略配置指南
+
+## 一、什么是加密价差策略？
+
+加密价差策略是一种自动化交易策略，专门用于 Polymarket 加密市场的 **5分钟** 或 **15分钟** "Up or Down" 市场。
+
+**核心逻辑**：在指定时间窗口内，当市场价格进入您设定的价格区间时，系统会自动以固定价格（0.99）买入，无需手动操作。
+
+**适用场景**：
+- 您希望捕捉市场在周期末段的价格波动
+- 您想自动化执行交易，避免手动盯盘
+- 您对市场走势有一定判断，希望设置条件自动触发
+
+---
+
+## 二、策略工作原理
+
+### 2.1 基本流程
+
+```
+周期开始 → 时间窗口内 → 价格进入区间 → 自动下单
+```
+
+1. **周期**：每个市场按固定周期运行（5分钟或15分钟）
+   - 5分钟市场：每5分钟为一个周期（如 10:00、10:05、10:10...）
+   - 15分钟市场：每15分钟为一个周期（如 10:00、10:15、10:30...）
+
+2. **时间窗口**：您可以在周期内设置一个时间段
+   - 例如：15分钟市场，设置窗口为「3分钟～12分钟」
+   - 表示：从周期开始后第3分钟到第12分钟之间才会触发
+
+3. **价格区间**：设置触发价格范围
+   - 例如：最低价 0.50，最高价 0.80
+   - 表示：当市场价格在 0.50～0.80 之间时才会触发
+
+4. **自动下单**：满足条件后，系统自动以 0.99 的价格买入
+
+### 2.2 重要限制
+
+- **每周期最多触发一次**：同一个周期内，即使多次满足条件，也只下单一次
+- **固定下单价格**：所有订单都以 0.99 的价格提交
+- **需要单独钱包**：建议使用专门的钱包运行加密价差策略，避免与其他操作（手动交易、跟单等）冲突

+| **时间窗口开始** | 从周期起点算起，多少分钟后开始监听 | ✅ | 3分0秒 |
+| **时间窗口结束** | 从周期起点算起，多少分钟后停止监听 | ✅ | 12分0秒 |
+
+**时间窗口说明**：
+- 5分钟市场：可选 0～5 分钟内的任意时间段
+- 15分钟市场：可选 0～15 分钟内的任意时间段
+- **开始时间必须 ≤ 结束时间**
+- 窗口外的时间即使价格满足也不会触发
+
+**示例**：
+- 15分钟市场，窗口「3分0秒 ～ 12分0秒」
+  - 周期开始后 0～3 分钟：不监听
+  - 周期开始后 3～12 分钟：监听价格，满足条件即触发
+  - 周期开始后 12～15 分钟：不监听
+
+### 3.3 价格区间
+
+| 参数 | 说明 | 必填 | 取值范围 | 示例 |
+|------|------|------|----------|------|
+| **最低价 (minPrice)** | 触发的最低价格 | ✅ | 0～1 | 0.50 |
+| **最高价 (maxPrice)** | 触发的最高价格 | ❌ | 0～1，默认1 | 0.80 |
+
+**价格区间说明**：
+- 价格范围是 0～1 之间的小数
+- 当市场价格在 [最低价, 最高价] 区间内时才会触发
+- 如果不填最高价，默认使用 1.0（即只要价格 ≥ 最低价就触发）
+
+**示例**：
+- 最低价 0.50，最高价 0.80
+  - 价格 0.45：不触发（低于最低价）
+  - 价格 0.60：触发 ✅（在区间内）
+  - 价格 0.85：不触发（高于最高价）
+
+### 3.4 投入金额
+
+| 参数 | 说明 | 必填 | 示例 |
+|------|------|------|------|
+| **投入方式** | 选择按比例或固定金额 | ✅ | 按比例 / 固定金额 |
+| **比例 (%)** | 按账户余额的百分比投入 | 条件必填 | 10%（账户有100 USDC，投入10 USDC） |
+| **固定金额 (USDC)** | 每次固定投入的金额 | 条件必填 | 50 USDC |
+
+**投入方式说明**：
+
+**方式一：按比例 (RATIO)**
+- 每次触发时，按账户当前可用余额的百分比投入
+- 例如：账户有 100 USDC，设置比例 10%
+  - 第1次触发：投入 10 USDC
+  - 第2次触发：如果余额变为 90 USDC，投入 9 USDC
+- **优点**：自动适应账户余额变化
+- **缺点**：每次投入金额可能不同
+
+**方式二：固定金额 (FIXED)**
+- 每次触发时，固定投入指定金额
+- 例如：设置固定金额 50 USDC
+  - 每次触发都投入 50 USDC
+- **优点**：投入金额稳定，便于管理
+- **缺点**：需要确保账户余额充足
+
+**注意事项**：
+- 最小下单金额：至少 1 USDC
+- 如果账户余额不足，下单会失败并记录失败原因
+
+### 3.5 价差过滤（高级功能）
+
+价差功能用于根据币安 BTC/USDC 的 K 线波动决定是否触发，支持「最小价差」与「最大价差」两种方向。
+
+| 参数 | 说明 | 必填 | 示例 |
+|------|------|------|------|
+| **价差模式** | 选择价差校验方式 | ✅ | 无 / 固定 / 自动 |
+| **价差方向** | 最小价差（≥ 触发）或 最大价差（≤ 触发） | ✅ | 最小价差 / 最大价差 |
+| **价差值** | 固定模式时填写（单位：USDC） | 条件必填 | 30 |
+
+**价差方向说明**：
+
+- **最小价差**：当币安 K 线价差 **≥** 设定值时才触发  
+  - 适合：只在波动「足够大」时交易（避免波动过小、不值得进场）
+- **最大价差**：当币安 K 线价差 **≤** 设定值时才触发  
+  - 适合：只在波动「足够小」时交易（避免波动过大、风险高）
+
+**三种价差模式**：
+
+**模式一：无 (NONE)**
+- 不进行价差校验
+- 只要时间窗口和价格区间满足就触发
+- **适合**：不关心币安价格波动，只看 Polymarket 价格
+
+**模式二：固定 (FIXED)**
+- 设置一个固定的价差值（单位：USDC）
+- **最小价差**：当 K 线价差 ≥ 设定值时触发  
+  - 示例：设定 30，价差 ≥ 30 触发 ✅，价差 < 30 不触发
+- **最大价差**：当 K 线价差 ≤ 设定值时触发  
+  - 示例：设定 50，价差 ≤ 50 触发 ✅，价差 > 50 不触发
+- **适合**：您有明确的价差阈值
+
+**模式三：自动 (AUTO)**
+- 系统根据历史 20 根 K 线自动计算基准价差
+- 计算逻辑：
+  1. 获取最近 20 根 K 线（与策略周期一致）
+  2. 按方向筛选（Up 方向只看上涨的 K 线，Down 方向只看下跌的 K 线）
+  3. 剔除异常值（使用 IQR 方法）
+  4. 计算平均价差 × 0.8 作为有效价差
+- **最小价差**：K 线价差 ≥ 有效价差时触发  
+- **最大价差**：K 线价差 ≤ 有效价差时触发
+- **适合**：希望根据历史数据自动调整，无需手动设具体数值
+
+**价差说明**：
+- 价差 = |收盘价 - 开盘价|（币安 BTC/USDC 当根 K 线）
+- 例如：开盘价 50000，收盘价 50030，价差 = 30
+- 价差越大，说明该周期内价格波动越大

+## 四、配置示例
+
+### 示例1：简单策略（5分钟市场）
+
+**场景**：在 5 分钟市场的最后 2 分钟，如果价格低于 0.60，自动买入 10 USDC
+
+**配置**：
+```
+账户：账户A

+价差模式：无
+启用状态：开启
+```
+
+**说明**：
+- 周期开始后 0～3 分钟：不监听
+- 周期开始后 3～5 分钟：如果价格 ≤ 0.60，自动买入 10 USDC
+
+---
+
+### 示例2：比例投入策略（15分钟市场）
+
+**场景**：在 15 分钟市场的中段（5～10分钟），如果价格在 0.40～0.70 之间，投入账户余额的 15%
+
+**配置**：
+```
+账户：账户B
+策略名称：BTC 15分钟比例策略
+市场：btc-updown-15m
+时间窗口：5分0秒 ～ 10分0秒
+最低价：0.40
+最高价：0.70
+投入方式：按比例
+比例：15%
+价差模式：无
+启用状态：开启
+```
+
+**说明**：
+- 假设账户余额 100 USDC
+- 周期开始后 5～10 分钟：如果价格在 0.40～0.70 之间，自动买入约 15 USDC（100 × 15%）
+
+---
+
+### 示例3：带价差过滤的策略（15分钟市场）
+
+**场景**：在 15 分钟市场的后段（10～14分钟），如果价格在 0.50～0.80 之间，且币安价差 ≥ 50，投入 20 USDC
+
+**配置**：
+```
+账户：账户C
+策略名称：BTC 15分钟价差策略
+市场：btc-updown-15m
+时间窗口：10分0秒 ～ 14分0秒
+最低价：0.50
+最高价：0.80
+投入方式：固定金额
+固定金额：20 USDC
+价差模式：固定
+价差方向：最小价差

+  1. 价格在 0.50～0.80 之间 ✅
+  2. 价差方向为「最小价差」且币安价差 ≥ 50 ✅
+- 如果价差只有 30，即使价格满足也不会触发
+
+---
+
+### 示例4：自动价差策略（15分钟市场）
+
+**场景**：在 15 分钟市场的前段（2～8分钟），如果价格在 0.30～0.90 之间，投入账户余额的 20%，价差由系统自动计算
+
+**配置**：
+```
+账户：账户D
+策略名称：BTC 15分钟自动价差策略
+市场：btc-updown-15m
+时间窗口：2分0秒 ～ 8分0秒
+最低价：0.30
+最高价：0.90
+投入方式：按比例
+比例：20%
+价差模式：自动
+价差方向：最小价差
+启用状态：开启
+```
+
+**说明**：
+- 系统会根据历史 20 根 K 线自动计算有效价差
+- 周期开始后 2～8 分钟：同时满足以下条件才触发
+  1. 价格在 0.30～0.90 之间 ✅
+  2. 价差方向为「最小价差」且币安价差 ≥ 系统计算的有效价差 ✅
+
+---
+
+## 五、常见问题
+
+### Q1：策略什么时候会触发？
+
+**A**：需要同时满足以下条件：
+1. ✅ 当前时间在时间窗口内
+2. ✅ 市场价格在 [最低价, 最高价] 区间内
+3. ✅ 本周期尚未触发过（每周期最多触发一次）
+4. ✅ 如果设置了价差过滤，币安价差与价差方向需同时满足条件
+
+### Q2：为什么我的策略没有触发？
+
+**可能原因**：
+1. **时间窗口不对**：当前时间不在设定的时间窗口内
+2. **价格不在区间**：市场价格不在 [最低价, 最高价] 范围内
+3. **本周期已触发**：该周期已经触发过一次，不会再触发
+4. **价差不满足**：如果设置了价差过滤，币安价差或价差方向未满足要求
+5. **账户余额不足**：账户余额小于设定的投入金额
+6. **策略未启用**：检查策略的启用状态是否为"开启"
+
+### Q3：每周期最多触发一次是什么意思？
+
+**A**：每个周期（5分钟或15分钟）内，即使多次满足条件，也只下单一次。
+
+**示例**：
+- 15分钟市场，周期从 10:00 开始
+- 10:05 时价格满足条件，触发下单 ✅
+- 10:08 时价格再次满足条件，但不会再次下单（本周期已触发）
+- 10:15 开始新周期，可以再次触发
+
+### Q4：固定金额和按比例有什么区别？
+
+**固定金额**：
+- 每次触发都投入相同金额
+- 例如：设置 50 USDC，每次都是 50 USDC
+- 需要确保账户余额充足
+
+**按比例**：
+- 每次触发时按账户余额的百分比投入
+- 例如：设置 10%，账户有 100 USDC 时投入 10 USDC，余额变为 90 USDC 后下次投入 9 USDC
+- 自动适应余额变化
+
+### Q5：价差过滤功能有什么用？
+
+**A**：价差过滤根据币安 BTC/USDC 的 K 线波动决定是否触发，支持两种方向。
+
+**最小价差**（价差 ≥ 设定值才触发）：
+- 波动太小时不触发，避免在波动不足时进场
+- 例如：设定 30，只有价差 ≥ 30 才触发
+
+**最大价差**（价差 ≤ 设定值才触发）：
+- 波动太大时不触发，避免在波动过大、风险高时进场
+- 例如：设定 50，只有价差 ≤ 50 才触发
+
+**三种模式选择建议**：
+- **无**：不关心币安价格波动，只看 Polymarket 价格
+- **固定**：您知道期望的价差阈值（配合最小/最大价差方向使用）
+- **自动**：希望根据历史数据自动计算有效价差，无需手动设具体数值
+
+### Q6：为什么建议使用单独的钱包？
+
+**A**：避免以下问题：
+1. **余额变化**：如果钱包同时用于手动交易，余额变化可能影响策略执行
+2. **仓位冲突**：手动交易和策略交易可能产生冲突
+3. **管理混乱**：难以区分哪些订单是策略产生的，哪些是手动产生的
+
+**建议**：创建一个专门的钱包，只用于加密价差策略。
+
+### Q7：下单价格为什么是固定的 0.99？
+
+**A**：这是策略的设计特点：
+- 0.99 是市场中的最高价格（接近 1.0）
+- 以最高价买入可以确保订单快速成交
+- 虽然买入价格较高，但策略的核心是捕捉市场波动，而非追求最优价格
+
+### Q8：策略需要依赖自动赎回功能吗？
+
+**A**：是的，加密价差策略依赖自动赎回功能。
+
+**原因**：
+- 策略下单后会形成仓位
+- 这些仓位需要在市场结算后自动赎回
+- 如果未配置自动赎回，仓位可能无法及时赎回
+
+**配置要求**：
+- 在「系统设置」中配置 Builder API Key
+- 开启自动赎回功能
+
+---
+
+## 六、注意事项
+
+### 6.1 账户要求
+
+- ✅ 账户必须配置 API Key、API Secret、API Passphrase
+- ✅ 账户必须有足够的 USDC 余额
+- ✅ 建议使用专门的钱包，避免与其他操作冲突
+
+### 6.2 时间窗口设置
+
+- ⚠️ 开始时间必须 ≤ 结束时间
+- ⚠️ 时间窗口不能超出周期长度（5分钟市场 ≤ 5分钟，15分钟市场 ≤ 15分钟）
+- ⚠️ 建议设置合理的时间窗口，避免在周期开始或结束时触发
+
+### 6.3 价格区间设置
+
+- ⚠️ 最低价必须 ≤ 最高价
+- ⚠️ 价格范围是 0～1 之间的小数
+- ⚠️ 建议根据市场情况设置合理的价格区间
+
+### 6.4 投入金额设置
+
+- ⚠️ 最小下单金额：至少 1 USDC
+- ⚠️ 确保账户余额充足，避免下单失败
+- ⚠️ 按比例模式：注意账户余额变化对投入金额的影响
+
+### 6.5 价差过滤设置
+
+- ⚠️ 价差方向：最小价差为「≥ 触发」，最大价差为「≤ 触发」，请按需求选择
+- ⚠️ 固定模式：需要填写合理的价差值（单位：USDC）
+- ⚠️ 自动模式：系统会在周期内按窗口进度自动计算有效价差，无需手动设置
+- ⚠️ 价差设定过严（最小价差设得过大或最大价差设得过小）可能导致策略难以触发
+
+### 6.6 其他注意事项
+
+- ⚠️ 策略创建后默认启用，如需暂停可以关闭"启用状态"
+- ⚠️ 每周期最多触发一次，请合理设置触发条件
+- ⚠️ 策略依赖自动赎回功能，请确保已配置 Builder API Key
+- ⚠️ 建议定期查看触发记录，了解策略执行情况
+
+---

+# Neg Risk 赎回与对应 JS/TS 代码说明
+
+## Neg Risk 特殊逻辑
+
+### 1. 赎回（Redeem）
+
+- **普通市场**：仓位由 **USDC.e**（Bridged USDC）抵押，调用 CTF 的 `redeemPositions(collateralToken, parentCollectionId, conditionId, indexSets)` 时，`collateralToken` 为 USDC.e 地址（Polygon: `0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174`）。
+- **Neg Risk 市场**：仓位由 **WrappedCollateral** 抵押（neg-risk-ctf-adapter 设计），同一笔赎回必须使用 WrappedCollateral 地址（Polygon: `0x3A3BD7bb9528E159577F7C2e685CC81A765002E2`），否则链上找不到对应仓位，会得到 payout 0。
+
+本项目中：通过 Gamma API 的 `negRisk` / `negRiskOther` 判断市场类型，赎回时对 Neg Risk 市场传 `isNegRisk=true`，在 `createRedeemTx` 中选用 WrappedCollateral 作为 `collateralToken`。
+
+### 2. 下单/签约（Order Signing）
+
+- **普通市场**：使用标准 CTF Exchange 合约签约。
+- **Neg Risk 市场**：必须使用 **Neg Risk CTF Exchange** 合约签约，否则 CLOB 返回 invalid signature。
+
+见 `OrderSigningService.getExchangeContract(negRisk)`、`CopyOrderTrackingService` 中按 `getNegRiskByConditionId` 选择 exchange。

+## 赎回后自动解包 WCOL → USDC.e
+
+Neg Risk 赎回到账为 **WCOL**，若不解包则余额显示为 WCOL 而非 USDC.e。本项目中由**轮询任务**统一解包，赎回流程内不再等待确认与解包：
+
+- **WcolUnwrapJobService**：每 20 秒轮询一次（`@Scheduled(fixedRate = 20_000)`），遍历所有账户的代理地址，若 WCOL 余额 > 0 则调用 **BlockchainService.unwrapWcolForProxy** 解包为 USDC.e。同一时间仅允许单次执行；若上次执行未结束则本次忽略。
+- **AccountService.redeemPositions**：只负责赎回，不再在流程内等待交易确认或执行解包；解包由上述 Job 在后续轮询中处理（含重启后未解包、解包失败重试等）。
+- **BlockchainService**：提供 `getWcolBalance(proxyAddress)`、`unwrapWcolForProxy(...)`；**RelayClientService** 提供 `createUnwrapWcolTx(toAddress, amountWei)`。
+- **Safe 与 Magic 解包逻辑一致**：均使用同一 `createUnwrapWcolTx(proxyAddress, balance)` 与 `execute(privateKey, proxyAddress, unwrapTx, walletType)`；Safe 走 execTransaction（或 Builder Relayer SAFE），Magic 走 Builder Relayer PROXY（encodeProxyTransactionData），最终均为代理合约调用 WCOL.unwrap(proxyAddress, amount)，USDC.e 转入该代理地址。
+
+## 小结
+
+- **Neg Risk 特殊逻辑**：赎回用 WrappedCollateral、下单用 Neg Risk Exchange；均由「是否为 Neg Risk 市场」分支处理。
+- **对应 JS 代码**：执行与 MultiSend 在 **builder-relayer-client**；赎回参数与 calldata 在**应用层**构建，官方无现成 redeem 工具；Neg Risk 的抵押品与合约见 **neg-risk-ctf-adapter** 与 **Gamma API**。
