+# 📈 PolyWeather 模拟仓 (Paper Trading) 使用指南
+
+本系统提供全自动的模拟交易功能，让您在不投入真实资金的情况下，验证天气预测逻辑的盈利能力。
+
+## 🛠️ 运行机制
+
+1.  **自动开仓**:
+    - 监控引擎在扫描中，一旦发现任何档位的 **Buy Yes** 或 **Buy No** 价格处于 **85¢ - 95¢** 区间（与城市监控报告一致），即触发买入。
+    - 初始本金: **$1000.00**
+    - 单笔投入: **$5.00**
+    - 资金检查: 余额不足时将停止开仓。
+2.  **实时估值**:
+    - 每轮扫描结束后，系统会根据最新盘口中间价更新持仓价值。
+3.  **数据持久化**:
+    - 持仓与余额保存在 `data/paper_positions.json`。
+
+## 📊 盈亏计算公式
+
+- **持仓份额** = $5 / (买入价格 / 100)
+- **可用余额** = 初始本金 - 累计投入总额
+- **浮动盈亏** = 当前总价值 - 投入本金 ($5)
+
+## 🤖 电报指令
+
+您可以直接在机器人中通过以下指令查看进度：
+
+- **/portfolio**: 实时返回当前所有“浮动”持仓的盈亏状况、历史胜率以及账户余额。
+
+## 📁 存储文件说明
+
+如果您需要手动清理或修改仓位，可以编辑 `data/paper_positions.json`。
+
+- `status: "OPEN"` 表示正在持仓。
+- `entry_price` 以美分为单位（如 91 表示 0.91$）。
