MQL4自动停止

Question

如果达到或超过先前手动设置的限制，我的 Martingale EA 应该会自动停止。最后一笔交易应该正常到期，不会被打断。

到目前为止，我已经尝试了以下代码，没有中断等。代码工作正常。我也听说过 RemoveExpert，但我不知道该怎么做。感谢您的帮助:)

enum tradeD{Buy=1, Sell=2};
input tradeD   TradeType   = Buy;
input double   Initial_Lot = 0.01;
input double   Lot_Factor  = 2;

input double   Pct_SL      = 0.1;  // Percentage Stop Loss
input double   Pct_TP      = 0.1;  // Percentage Take Profit
input int      Magic_Number= 73726;
input int      interrupt   = 1,0000;
