 - **价格模式**：填完币种、方向、止损价、止盈价后，调用 `GET /api/order_defaults` 取标记价，按几何距离计算 RR。
 - **百分比模式**：填完币种、方向、止损%、止盈% 后拉快照校验币种，再显示 RR（`止盈% / 止损%`）。
-- **固定盈亏比模式**：填完币种、方向、止损价、盈亏比后取价校验几何合法，展示填写的盈亏比。
+- **固定盈亏比模式**：不显示预估盈亏比（盈亏比由输入框直接指定；仍保留原有「预估止盈」）。
 
 与计仓方式无关：**以损定仓**（`POSITION_SIZING_MODE=risk`）与 **全仓杠杆**（`full_margin`）均显示同一预估。
