fix: 修复固定金额模式卖出数量计算逻辑

- 删除卖出订单的 notificationSent 字段，使用 priceUpdated 作为共用字段
- 添加 leaderBuyQuantity 字段，在创建 CopyOrderTracking 时存储 Leader 买入数量
- 修复固定金额模式下卖出数量计算：优先使用存储的 leaderBuyQuantity，避免 API 查询失败
- 添加数据库迁移 V14 和 V15
- 优化 calculateSellQuantityForFixedMode 方法，支持新数据和旧数据兼容

+# 🎉 v1.1.0 版本更新指南
+
+## 📅 发布日期
+
+2025年12月26日
+
+## 🎯 这次更新对您意味着什么？

+- **实时链上监听**：通过 WebSocket 实时监听链上交易，跟单响应速度提升 50% 以上
+- **双重保障**：链上监听和轮询同时运行，确保不错过任何交易机会
+- **自动去重**：系统自动处理重复数据，确保每笔交易只执行一次
+
+### 💰 更准确的盈亏统计
+- **实际成交价追踪**：系统会自动更新卖出订单的实际成交价，而不是下单时的价格
+- **自动价格更新**：每 5 秒自动查询并更新订单的实际成交价
+- **精确盈亏计算**：基于实际成交价计算盈亏，统计数据更准确
+
+### 🔧 更灵活的系统配置
+- **RPC 节点管理**：可以添加、编辑、删除自定义 RPC 节点
+- **节点启用/禁用**：可以随时启用或禁用节点，无需删除配置
+- **智能节点选择**：系统自动选择可用的节点，禁用的节点会被忽略
+
+### 🐛 问题修复
+- **修复卖出订单失败问题**：修复了部分情况下卖出订单因 API 凭证问题导致的失败
+- **修复订单精度错误**：修复了卖出订单因精度问题导致的 API 错误
+
+## 📦 如何更新
+
+### 方式一：使用 Docker（推荐）
+
+#### 步骤 1：备份数据（强烈推荐）
+
+**备份不是必须的，但强烈推荐！**
+
+**为什么需要备份？**
+- Docker 更新不会删除数据（数据存储在独立的数据卷中）
+- 但数据库结构可能会变更（本次更新会添加 `price_updated` 字段）
+- 如果迁移失败或出现问题，备份可以帮助恢复数据
+- 生产环境建议必须备份，开发环境可以跳过
+
+**如何备份？**
+
+```bash
+# 方式 1：使用 mysqldump 备份数据库（推荐）
+docker exec polyhermes-mysql mysqldump -u root -p polyhermes > backup_$(date +%Y%m%d_%H%M%S).sql
+
+# 方式 2：备份整个 MySQL 数据卷
+docker run --rm -v polyhermes_mysql-data:/data -v $(pwd):/backup alpine tar czf /backup/mysql_backup_$(date +%Y%m%d_%H%M%S).tar.gz /data
+
+# 方式 3：如果已有定期备份，可以跳过此步骤
+```
+
+**什么情况下可以跳过备份？**
+- ✅ 开发环境或测试环境
+- ✅ 数据不重要或可以重新生成
+- ✅ 已经有定期自动备份
+- ✅ 确定迁移不会失败（查看更新日志确认）
+
+**什么情况下必须备份？**
+- ⚠️ 生产环境
+- ⚠️ 包含重要交易数据
+- ⚠️ 不确定迁移是否安全
+
+#### 步骤 2：停止当前服务
+
+```bash
+# 进入部署目录
+cd /path/to/polyhermes
+
+# 停止服务
+docker-compose -f docker-compose.prod.yml down
+```
+
+#### 步骤 3：拉取新版本
+
+```bash
+# 拉取 v1.1.0 版本
+docker pull wrbug/polyhermes:v1.1.0
+
+# 或者拉取最新版本（推荐）
+docker pull wrbug/polyhermes:latest
+```
+
+#### 步骤 4：更新配置（如果需要）
+
+如果您想固定使用 v1.1.0 版本，可以编辑 `docker-compose.prod.yml`：
+
+```yaml
+services:
+  app:
+    image: wrbug/polyhermes:v1.1.0  # 修改这里
+```
+
+#### 步骤 5：启动服务
+
+```bash
+# 启动服务
+docker-compose -f docker-compose.prod.yml up -d
+
+# 查看日志，确认服务正常启动
+docker-compose -f docker-compose.prod.yml logs -f
+```
+
+#### 步骤 6：验证更新
+
+1. 访问系统首页，查看页面标题是否显示 `v1.1.0`
+2. 检查系统功能是否正常
+3. 查看日志是否有错误信息
+
+### 方式二：一键更新脚本
+
+如果您使用 `latest` 标签，可以使用以下命令一键更新：
+
+```bash
+# 进入部署目录
+cd /path/to/polyhermes
+
+# 拉取最新镜像并重启
+docker-compose -f docker-compose.prod.yml pull
+docker-compose -f docker-compose.prod.yml up -d
+
+# 查看日志
+docker-compose -f docker-compose.prod.yml logs -f
+```
+
+## ⚠️ 更新注意事项
+
+### 1. 数据库迁移
+- 本次更新会自动执行数据库迁移（添加 `price_updated` 字段）
+- 迁移过程不会影响现有数据，只是添加新字段
+- 迁移是安全的，但如果迁移失败，请检查数据库权限和连接
+- **如果迁移失败，可以使用备份恢复数据**
+
+### 2. 服务中断时间
+- 更新过程中服务会短暂中断（通常 1-2 分钟）
+- 建议在低峰期进行更新
+- 更新期间正在进行的跟单操作可能会受影响
+
+### 3. 配置检查
+- 更新后请检查 RPC 节点配置是否正确
+- 如果使用自定义 RPC 节点，请确认节点状态正常
+
+### 4. 功能验证
+更新后建议验证以下功能：
+- ✅ 跟单功能是否正常
+- ✅ 订单价格更新是否正常
+- ✅ RPC 节点管理是否正常
+- ✅ 盈亏统计是否准确
+
+## 🆕 新功能使用指南
+
+### 1. RPC 节点管理
+
+#### 如何添加自定义 RPC 节点？
+
+1. 登录系统，进入 **系统设置** → **RPC 节点设置**
+2. 点击 **添加节点** 按钮
+3. 填写节点信息：
+   - **节点名称**：给节点起个名字（如：Alchemy Polygon）
+   - **RPC URL**：节点的 HTTP/HTTPS 地址
+   - **启用状态**：默认启用，可以稍后禁用
+4. 点击 **保存**
+
+#### 如何启用/禁用节点？
+
+1. 在 RPC 节点列表中，找到要操作的节点
+2. 点击 **启用/禁用** 开关
+3. 系统会自动更新节点状态
+
+**提示**：
+- 禁用的节点不会被使用，但配置会保留
+- 可以随时重新启用禁用的节点
+- 建议至少保留一个启用的节点
+
+### 2. 实际成交价追踪
+
+#### 这个功能做什么？
+
+系统会自动追踪卖出订单的实际成交价，而不是使用下单时的价格。这样可以：
+- 更准确地计算盈亏
+- 了解订单的实际执行情况
+- 优化卖出策略
+
+#### 如何查看实际成交价？
+
+1. 进入 **跟单统计** → **卖出订单**
+2. 查看订单列表，**卖出价格** 列显示的是实际成交价
+3. 如果价格旁边有更新标记，说明价格已从订单详情中获取
+
+**注意**：
+- 价格更新是自动的，每 5 秒检查一次
+- 如果订单还未成交，价格可能还是下单时的价格
+- 部分成交的订单会使用加权平均价格
+
+## 🔍 常见问题
+
+### Q1: 更新后无法启动怎么办？
+
+**A:** 请按以下步骤排查：
+
+1. 检查日志：`docker-compose -f docker-compose.prod.yml logs`
+2. 检查数据库连接是否正常
+3. 检查端口是否被占用
+4. 如果问题持续，可以回退到之前的版本：
+   ```bash
+   # 修改 docker-compose.prod.yml 中的镜像标签为之前的版本
+   # 例如：image: wrbug/polyhermes:v1.0.3
+   docker-compose -f docker-compose.prod.yml up -d
+   ```
+
+### Q2: 更新后跟单不工作怎么办？
+
+**A:** 请检查：
+
+1. RPC 节点是否正常（进入 RPC 节点设置查看）
+2. 跟单配置是否启用
+3. 账户 API 凭证是否有效
+4. 查看系统日志是否有错误信息
+
+### Q3: 如何回退到之前的版本？

+## 一、跟单信号检测
+
+### 1.1 监控方式
+
+系统使用**轮询方式**监控 Leader 的交易活动：
+
+- **数据源**：Polymarket Data API 的 `/activity` 接口
+- **轮询间隔**：默认 2 秒（可配置）
+- **查询参数**：
+  - `user`: Leader 钱包地址
+  - `type`: `["TRADE"]`（只查询交易类型）
+  - `limit`: 100（每次最多查询 100 条）
+  - `sortBy`: `TIMESTAMP`
+  - `sortDirection`: `DESC`（按时间戳降序，最新的在前）
+
+### 1.2 增量检测机制
+
+通过 **diff 算法**检测新增交易：
+
+1. **首次轮询**：
+   - 查询最近 100 条交易
+   - 缓存所有交易 ID（不处理）
+   - 标记首次轮询完成
+
+2. **后续轮询**：
+   - 查询最近 100 条交易
+   - 与缓存的交易 ID 集合进行 diff
+   - 找出新增的交易 ID
+   - 处理新增交易
+   - 更新缓存（添加新增的交易 ID）
+
+3. **去重机制**：
+   - 使用 `leaderId + tradeId` 作为唯一标识
+   - 在 `processed_trade` 表中记录已处理的交易
+   - 避免重复处理同一笔交易
+
+### 1.3 交易数据转换
+
+从 `UserActivityResponse` 转换为 `TradeResponse`：
+
+```kotlin
+TradeResponse(
+    id = activity.transactionHash,  // 交易ID（用于去重）
+    market = activity.conditionId,  // 市场ID
+    side = activity.side,  // "BUY" 或 "SELL"
+    price = activity.price,  // 交易价格
+    size = activity.size,  // 交易数量
+    timestamp = activity.timestamp,  // 时间戳（秒）
+    user = activity.proxyWallet,  // 用户钱包地址
+    outcomeIndex = activity.outcomeIndex,  // 结果索引（0=第一个outcome，1=第二个outcome）
+    outcome = activity.outcome  // 结果名称
+)
+```
+
+### 1.4 信号触发流程
+
+```
+轮询任务启动
+    ↓
+定期轮询所有 Leader（每 2 秒）
+    ↓
+查询 Leader 活动（/activity 接口）
+    ↓
+转换为 TradeResponse
+    ↓
+diff 检测新增交易
+    ↓
+调用 processTrade() 处理交易
+    ↓
+根据 side 字段判断：
+    - "BUY" → processBuyTrade()
+    - "SELL" → processSellTrade()
+```
+
+## 二、订单构建
+
+### 2.1 买入订单构建流程
+
+#### 2.1.1 前置检查
+
+1. **查找跟单关系**：
+   - 查询所有启用且支持该 Leader 的跟单配置
+   - 验证账户 API 凭证是否配置
+   - 验证账户是否启用
+
+2. **获取 Token ID**：
+   - 使用 `outcomeIndex` 和 `market` 获取 tokenId
+   - 支持多元市场（不限于 YES/NO）
+
+3. **计算买入数量**：
+   - **RATIO 模式**：`买入数量 = Leader 数量 × 跟单比例`
+   - **FIXED 模式**：`买入数量 = 固定金额 / 买入价格`
+
+4. **过滤条件检查**：
+   - 价格区间检查
+   - 仓位限制检查
+   - 市场分类检查
+   - 订单簿检查（获取最佳卖单价格）
+
+5. **价格调整**：
+   - 应用价格容忍度（`priceTolerance`）
+   - 买入价格 = Leader 价格 × (1 + 容忍度)
+   - 确保调整后的价格不低于最佳卖单价格
+
+#### 2.1.2 订单签名
+
+使用 `OrderSigningService.createAndSignOrder()` 创建并签名订单：
+
+1. **计算订单金额**：
+   - **BUY 订单**：
+     - `makerAmount = price × size`（USDC 金额，最多 2 位小数）
+     - `takerAmount = size`（shares 数量，最多 4 位小数）
+   - 转换为 wei（6 位小数）
+
+2. **生成订单参数**：
+   - `salt`: 时间戳（毫秒）
+   - `maker`: 代理钱包地址（proxyAddress）
+   - `signer`: 从私钥推导的签名地址
+   - `taker`: 零地址（0x0000...）
+   - `tokenId`: 从 outcomeIndex 获取
+   - `makerAmount`: 计算出的 maker 金额（wei）
+   - `takerAmount`: 计算出的 taker 金额（wei）
+   - `expiration`: "0"（永不过期）
+   - `nonce`: "0"
+   - `feeRateBps`: "0"
+   - `side`: "BUY"
+   - `signatureType`: 2（Browser Wallet）
+
+3. **EIP-712 签名**：
+   - 编码域分隔符（Exchange Contract + Chain ID）
+   - 编码订单消息哈希
+   - 计算结构化数据哈希
+   - 使用私钥签名（r + s + v）
+
+#### 2.1.3 创建订单请求
+
+构建 `NewOrderRequest`：
+
+```kotlin
+NewOrderRequest(
+    order = signedOrder,  // 签名的订单对象
+    owner = account.apiKey,  // API Key
+    orderType = "FAK",  // Fill-And-Kill（允许部分成交，未成交部分立即取消）
+    deferExec = false  // 立即执行
+)
+```
+
+#### 2.1.4 提交订单
+
+1. **创建 CLOB API 客户端**（带认证）：
+   - 使用账户的 API Key、Secret、Passphrase
+   - 解密 API 凭证
+
+2. **调用 API 创建订单**：
+   - `POST /orders`
+   - 带重试机制（最多重试 2 次）
+   - 每次重试都重新生成 salt 并重新签名
+
+3. **记录订单跟踪**：
+   - 保存到 `copy_order_tracking` 表
+   - 记录买入订单 ID、数量、价格等信息
+   - 状态：`filled`
+
+### 2.2 卖出订单构建流程
+
+#### 2.2.1 前置检查
+
+1. **查找跟单关系**：
+   - 查询所有启用且支持该 Leader 的跟单配置
+   - 验证是否支持卖出（`supportSell = true`）
+
+2. **计算需要匹配的数量**：
+   - `需要匹配数量 = Leader 卖出数量 × 跟单比例`
+
+3. **查找未匹配的买入订单**：
+   - 使用 `outcomeIndex` 匹配（支持多元市场）
+   - 按 FIFO 顺序（先进先出）
+   - 查询 `copy_order_tracking` 表中未匹配的订单
+
+4. **计算实际可卖出数量**：
+   - 按 FIFO 顺序匹配
+   - 支持部分匹配（一个买入订单可以被多次卖出匹配）
+
+#### 2.2.2 价格计算
+
+1. **优先使用订单簿 bestBid**：
+   - 查询订单簿（`getOrderbookByTokenId`）
+   - 获取最佳买单价格（bestBid）
+   - 使用 bestBid 作为卖出价格
+
+2. **备选方案**：
+   - 如果获取订单簿失败，使用 Leader 价格
+   - 卖出价格 = Leader 价格 × 0.9（固定按 90% 计算）
+
+#### 2.2.3 订单签名
+
+与买入订单类似，但：
+- `side`: "SELL"
+- **SELL 订单金额计算**：
+  - `makerAmount = size`（shares 数量，最多 4 位小数）
+  - `takerAmount = price × size`（USDC 金额，使用原始价格计算）
+
+#### 2.2.4 创建订单请求
+
+与买入订单相同：
+- `orderType`: "FAK"
+- `deferExec`: false
+
+#### 2.2.5 提交订单
+
+1. **调用 API 创建卖出订单**（带重试机制）
+
+2. **更新买入订单状态**：
+   - 更新 `copy_order_tracking` 表中的 `remainingQuantity`
+   - 如果完全匹配，状态更新为 `fully_matched`
+   - 如果部分匹配，状态更新为 `partially_matched`
+
+3. **记录匹配关系**：
+   - 保存到 `sell_match_record` 表（卖出匹配记录）
+   - 保存到 `sell_match_detail` 表（匹配明细，包含盈亏计算）
+
+## 三、关键配置
+
+### 3.1 跟单配置参数
+
+- `copyMode`: 跟单模式（"RATIO" 或 "FIXED"）
+- `copyRatio`: 跟单比例（RATIO 模式）
+- `fixedAmount`: 固定金额（FIXED 模式）
+- `priceTolerance`: 价格容忍度（买入时使用）
+- `supportSell`: 是否支持卖出
+- `enabled`: 是否启用
+
+### 3.2 订单类型
+
+- **FAK (Fill-And-Kill)**：
+  - 允许部分成交
+  - 未成交部分立即取消
+  - 快速响应 Leader 交易，避免订单长期挂单导致价格不匹配
+
+### 3.3 重试机制
+
+- **最多重试次数**：2 次（首次 + 1 次重试）
+- **重试延迟**：3 秒
+- **重试策略**：每次重试都重新生成 salt 并重新签名，确保签名唯一性
+
+## 四、数据流向
+
+```
+Leader 交易（链上）
+    ↓
+Polymarket Data API (/activity)
+    ↓
+轮询服务（CopyTradingPollingService）
+    ↓
+交易处理服务（CopyOrderTrackingService）
+    ↓
+订单签名服务（OrderSigningService）
+    ↓
+CLOB API (POST /orders)
+    ↓
+订单跟踪表（copy_order_tracking）
+```
+
+## 五、注意事项
+
+1. **去重机制**：
+   - 使用 `leaderId + tradeId` 作为唯一标识
+   - 在 `processed_trade` 表中记录已处理的交易
+   - 避免重复处理同一笔交易
+
+2. **价格调整**：
+   - 买入时应用价格容忍度（提高买入价格）
+   - 卖出时优先使用订单簿 bestBid，失败则使用 Leader 价格的 90%
+
+3. **订单簿检查**：
+   - 买入前检查订单簿中是否有可匹配的卖单
+   - 确保调整后的买入价格不低于最佳卖单价格
+
+4. **FIFO 匹配**：
+   - 卖出时按买入时间顺序匹配（先进先出）
+   - 支持部分匹配
+
+5. **错误处理**：
+   - 订单创建失败时记录到 `failed_trade` 表
+   - 支持重试机制（最多 2 次）
+   - 发送失败通知（如果配置了 `pushFailedOrders`）

+# 跟单监听策略：链上 WebSocket + 轮询并行方案
+
+## 一、方案概述
+
+系统**同时运行**两种监听方式，并行处理，哪个数据先返回就用哪个：
+
+1. **链上 WebSocket 监听**：通过 Polygon RPC 的 `eth_subscribe` 实时监听链上交易
+2. **轮询监听**：通过 Polymarket Data API 定期轮询交易记录
+
+**核心特点**：
+- 两种方式**并行运行**，不互相排斥
+- WS 断开时**不断重试连接**，不停止轮询
+- 哪个数据先返回就用哪个，确保最快响应
+- 通过去重机制确保同一笔交易只处理一次
+
+## 二、关键流程图
+
+```
+系统启动
+    ↓
+同时启动两种监听方式
+    ↓
+    ├─→ 链上 WS 监听（并行）
+    │       ↓
+    │   尝试连接 WS RPC
+    │       ↓
+    │   连接成功？
+    │       ├─→ 是 → 订阅 Leader 钱包地址
+    │       │       (eth_subscribe: USDC Transfer + ERC1155 Transfer)
+    │       │       ↓
+    │       │   实时接收交易日志
+    │       │       ↓
+    │       │   解析交易 receipt
+    │       │       ↓
+    │       │   转换为 TradeResponse
+    │       │       ↓
+    │       │   调用 processTrade()（去重检查）
+    │       │       ↓
+    │       │   连接断开？
+    │       │       ├─→ 是 → 等待重连延迟 → 重试连接（循环）
+    │       │       └─→ 否 → 继续监听
+    │       │
+    │       └─→ 否 → 等待重连延迟 → 重试连接（循环）
+    │
+    └─→ 轮询监听（并行）
+            ↓
+        定期轮询 (每 2 秒)
+            ↓
+        查询 /activity 接口
+            ↓
+        diff 检测新增交易
+            ↓
+        调用 processTrade()（去重检查）
+            ↓
+        继续轮询（循环）
+```
+
+## 三、并行处理流程
+
+```
+交易发生
+    ↓
+    ├─→ WS 监听（实时，秒级）
+    │       ↓
+    │   收到链上日志
+    │       ↓
+    │   解析并转换为 TradeResponse
+    │       ↓
+    │   调用 processTrade()
+    │       ↓
+    │   去重检查（processed_trade 表）
+    │       ├─→ 已处理 → 跳过
+    │       └─→ 未处理 → 处理交易
+    │
+    └─→ 轮询监听（延迟，2秒间隔）
+            ↓
+        轮询到新交易
+            ↓
+        转换为 TradeResponse
+            ↓
+        调用 processTrade()
+            ↓
+        去重检查（processed_trade 表）
+            ├─→ 已处理 → 跳过（WS 已处理）
+            └─→ 未处理 → 处理交易
+```
+
+## 三、实现方案
+
+### 3.1 服务架构
+
+```
+CopyTradingMonitorService (主服务)
+    ├─→ OnChainWsService (链上 WS 监听，独立运行)
+    └─→ CopyTradingPollingService (轮询监听，独立运行)
+```
+
+**关键点**：
+- 两个服务**独立运行**，互不影响
+- 主服务负责启动和协调两个服务
+- 两个服务都调用同一个 `processTrade()` 方法
+- 去重由 `processTrade()` 内部处理
+
+### 3.2 WS 重连机制
+
+**重连策略**：
+1. WS 连接断开时，**不停止轮询服务**
+2. 等待重连延迟（如 3 秒）
+3. 自动重试连接
+4. 连接成功后重新订阅所有 Leader
+5. 如果连接失败，继续重试（无限重试）
+
+**重连流程**：
+```
+WS 连接断开
+    ↓
+记录断开日志
+    ↓
+等待重连延迟（3秒）
+    ↓
+尝试重新连接
+    ↓
+连接成功？
+    ├─→ 是 → 重新订阅所有 Leader → 继续监听
+    └─→ 否 → 等待重连延迟 → 继续重试（循环）
+```
+
+**关键实现**：
+- 使用协程或后台线程持续重试
+- 不阻塞主流程
+- 轮询服务继续运行，不受 WS 状态影响
+
+### 3.3 去重机制
+
+**去重标识**：
+- 使用 `leaderId + transactionHash` 作为唯一标识
+- 在 `processed_trade` 表中记录已处理的交易
+
+**去重流程**：
+```
+收到交易数据（WS 或轮询）
+    ↓
+调用 processTrade(leaderId, trade, source)
+    ↓
+检查 processed_trade 表
+    ├─→ 已存在 → 跳过处理（返回成功）
+    └─→ 不存在 → 继续处理
+            ↓
+        处理交易（创建订单等）
+            ↓
+        保存到 processed_trade 表
+            ├─→ leaderId
+            ├─→ leaderTradeId (transactionHash)
+            ├─→ tradeType (BUY/SELL)
+            ├─→ source (onchain-ws / polling)
+            └─→ status (SUCCESS/FAILED)
+```
+
+**并发安全**：
+- 使用数据库唯一约束（`leaderId + leaderTradeId`）
+- 处理唯一约束冲突（并发情况下可能多个请求同时处理同一笔交易）
+- 如果冲突，再次查询确认状态
+
+### 3.4 链上 WS 监听实现要点
+
+**订阅参数**：
+- 钱包地址：Leader 的 `leaderAddress`
+- 订阅类型：
+  - USDC Transfer（`from` 或 `to` 为钱包地址）
+  - ERC1155 TransferSingle/Batch（`from` 或 `to` 为钱包地址）
+
+**消息处理流程**：
+1. 接收 `eth_subscription` 消息
+2. 提取 `transactionHash`
+3. 调用 RPC 获取交易 receipt
+4. 解析 USDC Transfer 和 ERC1155 Transfer 日志
+5. 计算交易方向（BUY/SELL）、数量、价格
+6. 调用 Gamma API 补齐市场元数据（conditionId、outcomeIndex 等）
+7. 转换为 `TradeResponse`
+8. 调用 `processTrade(leaderId, trade, "onchain-ws")` 处理交易（去重由内部处理）
+
+**重连实现**：
+```kotlin
+// 伪代码示例
+while (isActive) {
+    try {
+        // 尝试连接
+        val ws = connectWebSocket()
+        
+        // 订阅所有 Leader
+        subscribeAllLeaders(ws)
+        
+        // 监听消息
+        ws.listen { message ->
+            handleMessage(message)
+        }
+        
+        // 连接断开，等待重连
+        waitReconnectDelay()
+    } catch (e: Exception) {
+        logger.warn("WS 连接失败，等待重连: ${e.message}")
+        waitReconnectDelay()
+    }
+}
+```
+
+### 3.5 轮询监听实现要点
+
+**轮询流程**：
+1. 定期查询 `/activity` 接口（每 2 秒）
+2. 通过 diff 检测新增交易
+3. 转换为 `TradeResponse`
+4. 调用 `processTrade(leaderId, trade, "polling")` 处理交易（去重由内部处理）
+
+**关键点**：
+- 轮询服务**独立运行**，不受 WS 状态影响
+- 即使 WS 正常工作，轮询也继续运行（作为备份）
+- 去重机制确保不会重复处理同一笔交易
+
+## 四、配置参数
+
+### 4.1 RPC 配置获取
+
+**RPC 配置从后台配置中读取**，通过 `RpcNodeService` 获取：
+
+```kotlin
+// 获取 HTTP RPC URL
+val httpUrl = rpcNodeService.getHttpUrl()
+
+// 获取 WebSocket RPC URL
+val wsUrl = rpcNodeService.getWsUrl()
+
+// 获取可用节点配置（包含完整信息）
+val nodeResult = rpcNodeService.getAvailableNode()
+if (nodeResult.isSuccess) {
+    val node = nodeResult.getOrNull()
+    val httpUrl = node?.httpUrl
+    val wsUrl = node?.wsUrl
+}
+```
+
+**配置管理**：
+- **RPC 节点配置存储在数据库**（`rpc_node_config` 表），不从配置文件读取
+- 支持多个节点配置，按优先级选择
+- 支持健康检查，自动选择可用节点
+- 前端可以通过系统设置页面配置 RPC 节点
+- 配置变更后，WS 重连时会自动使用新配置
+
+**配置字段**：
+- `httpUrl`: HTTP RPC 地址
+- `wsUrl`: WebSocket RPC 地址（可选）
+- `enabled`: 是否启用
+- `priority`: 优先级（数字越小优先级越高）
+- `lastCheckStatus`: 最后检查状态（HEALTHY/UNHEALTHY/UNKNOWN）
+
+### 4.2 WS 连接配置
+
+```properties
+# WS 连接超时（毫秒）
+polygen.ws.connect.timeout=5000
+
+# WS 重连延迟（毫秒）
+polygen.ws.reconnect.delay=3000
+```
+
+### 4.3 WS 重连配置
+
+```properties
+# WS 重连延迟（毫秒）
+polygen.ws.reconnect.delay=3000
+
+# WS 重连最大延迟（毫秒，指数退避上限）
+polygen.ws.reconnect.max.delay=60000
+
+# WS 重连是否启用指数退避
+polygen.ws.reconnect.exponential.backoff=true
+```
+
+### 4.4 合约地址配置
+
+```properties
+# USDC 合约地址
+usdc.contract.address=0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174
+
+# ERC1155 合约地址（Polymarket）
+erc1155.contract.address=0x4d97dcd97ec945f40cf65f87097ace5ea0476045
+```
+
+## 五、并行方案优势
+
+### 5.1 双重保障
+
+- **实时性**：WS 提供秒级实时通知
+- **可靠性**：轮询作为备份，确保不遗漏交易
+- **容错性**：WS 断开时轮询继续工作，WS 恢复后自动继续
+
+### 5.2 性能优化
+
+- **最快响应**：哪个数据先返回就用哪个
+- **负载均衡**：两种方式并行，减少单点压力
+- **去重保护**：确保同一笔交易只处理一次
+
+### 5.3 实现简单
+
+- **无需切换逻辑**：两种方式始终运行
+- **独立管理**：WS 和轮询各自管理自己的状态
+- **易于维护**：逻辑清晰，易于调试
+
+## 六、注意事项
+
+1. **WS 重连策略**：
+   - WS 断开时**不断重试**，不停止轮询
+   - 使用指数退避策略，避免频繁重连
+   - 记录重连日志，便于监控
+
+2. **去重机制**：
+   - 使用 `leaderId + transactionHash` 作为唯一标识
+   - 在 `processTrade()` 方法内部统一处理去重
+   - 使用数据库唯一约束确保并发安全
+
+3. **性能考虑**：
+   - WS 模式下需要为每个 Leader 订阅日志
+   - 大量 Leader 时可能需要优化订阅策略（批量订阅）
+   - 轮询间隔可以适当调整（默认 2 秒）
+
+4. **错误处理**：
+   - WS 连接失败不影响轮询服务
+   - 记录详细的错误日志，便于排查问题
+   - 两种方式的错误独立处理，互不影响
+
+5. **元数据补齐**：
+   - 链上数据不包含市场元数据（conditionId、outcomeIndex 等）
+   - 需要通过 Gamma API 或内部元数据服务补齐
+   - 轮询数据已包含元数据，无需额外补齐
+
+6. **数据源标识**：
+   - WS 数据：`source = "onchain-ws"`
+   - 轮询数据：`source = "polling"`
+   - 便于统计和分析不同数据源的处理情况
+
+## 七、实现要点
+
+### 7.1 主服务启动
+
+```kotlin
+@Service
+class CopyTradingMonitorService(
+    private val rpcNodeService: RpcNodeService,
+    private val onChainWsService: OnChainWsService,
+    private val pollingService: CopyTradingPollingService
+) {
+    @PostConstruct
+    fun init() {
+        scope.launch {
+            // 同时启动两种监听方式
+            launch { onChainWsService.start() }  // WS 监听（独立协程）
+            launch { pollingService.start() }     // 轮询监听（独立协程）
+        }
+    }
+}
+```
+
+### 7.2 WS 服务实现（从后台配置获取 RPC）
+
+```kotlin
+@Service
+class OnChainWsService(
+    private val rpcNodeService: RpcNodeService,
+    private val copyOrderTrackingService: CopyOrderTrackingService
+) {
+    suspend fun start() {
+        while (isActive) {
+            try {
+                // 从后台配置获取 WS RPC URL
+                val wsUrl = rpcNodeService.getWsUrl()
+                val httpUrl = rpcNodeService.getHttpUrl()
+                
+                // 连接并订阅
+                connectAndSubscribe(wsUrl, httpUrl)
+                
+                // 连接成功后持续监听
+                waitForDisconnect()
+            } catch (e: Exception) {
+                logger.warn("WS 连接失败，等待重连: ${e.message}")
+                delay(reconnectDelay)
+            }
+        }
+    }
+    
+    private suspend fun connectAndSubscribe(wsUrl: String, httpUrl: String) {
+        // 使用 wsUrl 和 httpUrl 连接和订阅
+        // ...
+    }
+}
+```
+
+**关键点**：
+- 每次重连时都从 `RpcNodeService` 获取最新的 RPC 配置
+- 如果配置变更，下次重连时会自动使用新配置
+- 支持多个节点配置，自动选择可用节点
+
+### 7.3 RPC 配置变更处理
+
+**配置变更时的处理**：
+- WS 连接断开时，下次重连会从 `RpcNodeService` 获取最新配置
+- 如果当前使用的节点不可用，`getAvailableNode()` 会自动选择下一个可用节点
+- 支持动态切换节点，无需重启服务
+
+**节点选择策略**：
+1. 优先使用 `lastCheckStatus = HEALTHY` 的节点
+2. 按 `priority` 排序，数字越小优先级越高
+3. 如果所有节点都不可用，返回失败（不降级到默认节点，因为默认节点可能也不可用）

+### 7.4 线程安全保证（单实例推荐方案）
+
+`processTrade` 方法需要保证线程安全，因为：
+- WS 和轮询可能同时处理同一笔交易
+- 多个协程可能并发调用 `processTrade`
+- 需要确保同一笔交易只处理一次
+
+**推荐方案：使用 Mutex（应用级锁）**
+
+对于单实例部署，**最轻量的方案是使用 Kotlin 协程的 Mutex**：
+- ✅ 无需额外依赖（不需要 Redis）
+- ✅ 性能开销小（内存锁，无网络开销）
+- ✅ 实现简单（Kotlin 标准库）
+- ✅ 协程友好（支持 suspend 函数）
+
+**实现代码**：
+
+```kotlin
+@Service
+open class CopyOrderTrackingService(
+    // ... 其他依赖
+) {
+    // 使用 Mutex 保证线程安全（按交易ID锁定）
+    private val tradeMutexMap = ConcurrentHashMap<String, Mutex>()
+    
+    /**
+     * 获取或创建 Mutex（按交易ID）
+     */
+    private fun getMutex(leaderId: Long, tradeId: String): Mutex {
+        val key = "${leaderId}_${tradeId}"
+        return tradeMutexMap.getOrPut(key) { Mutex() }
+    }
+    
+    /**
+     * 清理不再使用的 Mutex（可选，避免内存泄漏）
+     */
+    private fun cleanupMutex(leaderId: Long, tradeId: String) {
+        val key = "${leaderId}_${tradeId}"
+        // 延迟清理，避免频繁创建/删除
+        // 可以定期清理或使用 WeakReference
+    }
+    
+    /**
+     * 处理交易事件（WebSocket 或轮询）
+     * 使用 Mutex 保证线程安全
+     */
+    @Transactional
+    suspend fun processTrade(leaderId: Long, trade: TradeResponse, source: String): Result<Unit> {
+        // 获取该交易的 Mutex
+        val mutex = getMutex(leaderId, trade.id)
+        
+        return mutex.withLock {
+            try {
+                // 1. 检查是否已处理（去重）
+                val existingProcessed = processedTradeRepository.findByLeaderIdAndLeaderTradeId(
+                    leaderId, 
+                    trade.id
+                )
+                
+                if (existingProcessed != null) {
+                    if (existingProcessed.status == "FAILED") {
+                        return@withLock Result.success(Unit)
+                    }
+                    return@withLock Result.success(Unit)
+                }
+                
+                // 检查是否已记录为失败交易
+                val failedTrade = failedTradeRepository.findByLeaderIdAndLeaderTradeId(
+                    leaderId,

+                    "BUY" -> processBuyTrade(leaderId, trade)
+                    "SELL" -> processSellTrade(leaderId, trade)
+                    else -> {
+                        logger.warn("未知的交易方向: ${trade.side}")
+                        Result.failure(IllegalArgumentException("未知的交易方向: ${trade.side}"))
+                    }
+                }
+                
+                if (result.isFailure) {
+                    logger.error(

+                    return@withLock result
+                }
+                
+                // 3. 标记为已处理（成功状态）
+                // 由于使用了 Mutex，这里不会出现并发冲突
+                try {
+                    val processed = ProcessedTrade(
+                        leaderId = leaderId,
+                        leaderTradeId = trade.id,
+                        tradeType = trade.side.uppercase(),
+                        source = source,
+                        status = "SUCCESS",
+                        processedAt = System.currentTimeMillis()
+                    )
+                    processedTradeRepository.save(processed)
+                } catch (e: Exception) {
+                    // 理论上不会发生，但保留异常处理作为兜底
+                    if (isUniqueConstraintViolation(e)) {
+                        val existing = processedTradeRepository.findByLeaderIdAndLeaderTradeId(
+                            leaderId, 
+                            trade.id
+                        )
+                        if (existing != null) {
+                            logger.debug("交易已处理（并发检测）: leaderId=$leaderId, tradeId=${trade.id}")
+                            return@withLock Result.success(Unit)
+                        }
+                    } else {
+                        throw e
+                    }
+                }
+                
+                Result.success(Unit)
+            } catch (e: Exception) {
+                logger.error("处理交易异常: leaderId=$leaderId, tradeId=${trade.id}", e)
+                Result.failure(e)
+            }
+        }
+    }
+}
+```
+
+**关键点**：
+1. **按交易ID锁定**：每个交易使用独立的 Mutex，不同交易可以并行处理
+2. **Mutex 复用**：使用 `ConcurrentHashMap` 缓存 Mutex，避免频繁创建
+3. **协程友好**：`Mutex.withLock` 是 suspend 函数，不会阻塞线程
+4. **性能优化**：只锁定同一笔交易，不影响其他交易的并发处理
+
+**当前实现（基于数据库唯一约束，作为兜底）**：
+
+```kotlin
+@Transactional
+suspend fun processTrade(leaderId: Long, trade: TradeResponse, source: String): Result<Unit> {
+    // 1. 检查是否已处理（去重）
+    val existingProcessed = processedTradeRepository.findByLeaderIdAndLeaderTradeId(
+        leaderId, 
+        trade.id
+    )
+    
+    if (existingProcessed != null) {
+        return Result.success(Unit)  // 已处理，跳过
+    }
+    
+    // 2. 处理交易逻辑
+    val result = when (trade.side.uppercase()) {
+        "BUY" -> processBuyTrade(leaderId, trade)
+        "SELL" -> processSellTrade(leaderId, trade)
+        else -> Result.failure(IllegalArgumentException("未知的交易方向"))
+    }
+    
+    if (result.isFailure) {
+        return result
+    }
+    
+    // 3. 标记为已处理（使用数据库唯一约束保证并发安全）
+    try {
+        val processed = ProcessedTrade(
+            leaderId = leaderId,
+            leaderTradeId = trade.id,
+            tradeType = trade.side.uppercase(),
+            source = source,
+            status = "SUCCESS",
+            processedAt = System.currentTimeMillis()
+        )
+        processedTradeRepository.save(processed)
+    } catch (e: Exception) {
+        // 处理唯一约束冲突（并发情况下可能发生）
+        if (isUniqueConstraintViolation(e)) {
+            // 再次检查确认状态
+            val existing = processedTradeRepository.findByLeaderIdAndLeaderTradeId(
+                leaderId, 
+                trade.id
+            )
+            if (existing != null) {
+                logger.debug("交易已处理（并发检测）: leaderId=$leaderId, tradeId=${trade.id}")
+                return Result.success(Unit)
+            }
+        } else {
+            throw e
+        }
+    }
+    
+    return Result.success(Unit)
+}
+```
+
+**线程安全机制**：
+
+1. **数据库唯一约束**：
+   - `UNIQUE KEY uk_leader_trade (leader_id, leader_trade_id)`
+   - 确保同一笔交易只能插入一次
+   - 即使两个线程同时通过检查，也只有一个能成功保存
+
+2. **事务隔离**：
+   - 使用 `@Transactional` 注解
+   - 默认隔离级别（通常是 READ_COMMITTED）
+   - 保证事务内的数据一致性
+
+3. **异常处理**：
+   - 捕获唯一约束冲突异常
+   - 重新查询确认状态
+   - 避免重复处理
+
+**潜在问题**：
+
+虽然数据库唯一约束可以防止重复插入，但在检查 `existingProcessed` 和保存 `processed` 之间存在时间窗口（TOCTOU），可能导致：
+- 两个线程同时通过检查
+- 两个线程都执行 `processBuyTrade` 或 `processSellTrade`
+- 虽然只有一个能成功保存 `processed`，但可能创建了重复的订单
+
+**其他方案（不推荐，仅作参考）**：
+
+**方案 1：使用数据库锁（SELECT FOR UPDATE）**
+- ❌ 需要修改 Repository 方法
+- ❌ 增加数据库负载
+- ❌ 不适合高并发场景
+
+**方案 2：使用分布式锁（Redis，仅适用于多实例）**
+- ❌ 需要 Redis 依赖
+- ❌ 有网络开销
+- ❌ 单实例场景不需要
+
+**总结**：
+
+- ✅ **单实例部署推荐**：使用 **Mutex（应用级锁）**
+  - 最轻量：无需额外依赖，性能开销小
+  - 最简单：Kotlin 标准库，实现简单
+  - 最高效：内存锁，无网络开销，支持协程并发
+- ❌ **不推荐**：仅依赖数据库唯一约束（存在 TOCTOU 问题，可能创建重复订单）
+- ❌ **不推荐**：数据库锁或分布式锁（单实例场景过于复杂）
