我在我的代碼中對orderend和orderclose中的mql4有一些疑問

Question

我在外匯交易機器人上使用mql4有一個小專家，但是在運行此代碼以在Metatrader 4中進行回測時，我在獲取代碼時遇到了一些問題，我的代碼詳細信息是：我有2 ema，並且在交叉交易時買入，在交叉交易時賣出，但是在回測中損壞2 ema后獲得位置的問題。 我的止損定為10 pip，但tp為0，我們有開放交易直到2 ema的下一個交叉，然后關閉pervios頭寸並獲得新頭寸。 我添加測試立體聲，並顯示我的位置問題

Answer 1

我編輯了您的代碼。 您代碼中的主要問題是止盈！ 在GetBuy（）和GetSell（）函數中，您編寫了：

Ask+(TakeProfit*Point)

它返回詢問！ 因為您的TakeProfit已設置為零。 如果您不想設置止盈，請輸入：

int ticket = OrderSend(Symbol(),OP_BUY,Lots,Ask,Slippage,Ask-(StopLoss*Point),0,"Buy",MagicNumber,0,Blue);

這是新代碼：
