Binance Futures API创建Stop Market订单异常：仅生成首单后续失败求助

尝试通过Binance API创建和网页端一致的止损市价单（Stop Market），但频繁失败。少数成功的场景里，仅能生成首个止损市价单，后续的止损（Stop Loss）和止盈（Take Profit）订单都无法创建。报错信息无明确文档可查，附上相关代码求排查。

核心排查点与修正方案 #

1. 参数传递逻辑错误 #

• 调用止损单时，误将tp_price（止盈价）传给stop_price；调用止盈单时，误将sl_price（止损价）传给stop_price，触发条件完全颠倒，Binance会直接拒绝这类不符合交易逻辑的订单，需修正参数对应关系。
• 止盈单方向错误：止盈是平仓操作，方向必须和开仓方向相反，当前代码直接沿用开仓side，会导致反向开仓而非平仓，需修正为side="BUY" if "SELL" in side else "SELL"。

2. 订单类型与参数不匹配 #

• 当前take_profit_order使用FUTURE_ORDER_TYPE_TAKE_PROFIT（限价止盈），需要price和stopPrice配合，但网页端通常用市价止盈，应改为FUTURE_ORDER_TYPE_TAKE_PROFIT_MARKET，且无需传递price参数，否则会触发冗余参数校验错误。

3. 异常调试缺失 #

• 自定义异常仅抛出错误字符串，建议打印BinanceAPIException的code和message，Binance错误码有明确规则（如-2010为参数错误、-2019为持仓不足），可快速定位问题。

4. 持仓状态校验 #

• 首个止损市价单若未触发（仅为挂单状态），后续reduce_only=True的订单会因无持仓被拒绝。需确认开仓订单成交后再挂止盈止损，或使用Binance的条件单组合功能一次性提交开仓+止盈止损。
