基于EMA的动量策略止损止盈异常排查

我编写的基于EMA的动量策略脚本整体运行正常，但止损（Stop Loss）与止盈（Take Profit）退出订单存在异常——开启止损功能后，止盈指令完全无法执行。我确定这和退出条件的评估顺序有关，但多次调整结构都没能解决，麻烦帮忙排查。

原脚本如下：

//@version=5
strategy("Momentum Wolf v3", overlay=true)

// Input parameters
length = input.int(14, title="Length")
adxSmoothing = input.int(14, title="ADX Smoothing")

takeProfitEnabled = input.bool(true, title="Enable Take Profit")
stopLossValue = input.float(50, title="Stop Loss Value", minval=0, step=0.1)
takeProfitValue = input.float(100, title="Take Profit Value", minval=0, step=0.1)
allowedSessionStartHour = input.int(9, title="Allowed Trading Session Start Hour", minval=0, maxval=23)
allowedSessionStartMinute = input.int(30, title="Allowed Trading Session Start Minute", minval=0, maxval=59)

allowedSessionEndMinute = input.int(0, title="Allowed Trading Session End Minute", minval=0, maxval=59)
onlyPositiveDMI = input.bool(true, title="Take Longs only when DMI is Positive")
onlyNegativeDMI = input.bool(true, title="Take Shorts only when DMI is Negative")

// Custom function to check if the current time is within the allowed trading session
isAllowedSession() =>
    currentHour = hour(time)
    currentMinute = minute(time)
    sessionStartHour = allowedSessionStartHour
    sessionStartMinute = allowedSessionStartMinute
    sessionEndHour = allowedSessionEndHour
    sessionEndMinute = allowedSessionEndMinute
    
    // Check if the current time is within the allowed session
    (currentHour > sessionStartHour or (currentHour == sessionStartHour and currentMinute >= sessionStartMinute)) and (currentHour < sessionEndHour or (currentHour == sessionEndHour and currentMinute <= sessionEndMinute))

// Custom function to check if the current time is beyond the allowed session end time
isSessionEnded() =>
    currentHour = hour(time)
    currentMinute = minute(time)
    sessionEndHour = allowedSessionEndHour
    sessionEndMinute = allowedSessionEndMinute

    // Check if the current time is beyond the allowed session end time
    currentHour > sessionEndHour or (currentHour == sessionEndHour and currentMinute > sessionEndMinute)

问题根源

重复退出指令互相覆盖：对同一个持仓（如sell 1）分别调用了strategy.exit("sell SL")和strategy.exit("sell TP")，Pine Script中后执行的strategy.exit会覆盖之前的设置，导致同一时间只有止损或止盈其中一个生效。
退出逻辑顺序混乱：先处理DMI/收盘平仓条件，再设置止损止盈，若DMI条件触发，持仓会被提前平仓，止损止盈指令根本没有生效的机会。

修复方案

对同一个持仓，将止损和止盈合并到同一个strategy.exit调用中，通过profit和loss参数同时配置
调整逻辑顺序：先设置所有持仓的止损止盈，再处理DMI/收盘平仓条件，确保止损止盈在持仓存续期间始终有效
为每个持仓的退出指令设置唯一ID，避免不同持仓的退出逻辑互相干扰

关键修改点说明

合并止损止盈配置：对每个持仓用同一个strategy.exit调用，通过三元运算符判断是否启用止损/止盈，避免重复设置导致覆盖。
调整逻辑执行顺序：先设置止损止盈，再处理DMI/收盘平仓，确保止损止盈指令在持仓存续期间始终有效。
唯一退出ID：为每个持仓的退出指令设置独立ID，避免不同持仓的退出逻辑互相干扰。
