Question

我有一个外汇交易机器人的mql4专家但是我在运行此代码以在MetaTrader 4中进行回测时在获取代码时遇到了一些问题我的代码详细信息是：我有2个ema，何时交叉获得买入，何时向下交叉获得卖出但在回测中损坏2 ema后获得位置的问题。我的止损定为10 pip，但tp为0，我们有开放交易直到2 ema的下一个交叉，然后关闭pervios头寸并获得新头寸。我添加了测试立体声，并显示了我在定位上的问题

我编辑了您的代码。您代码中的主要问题是止盈！在GetBuy（）和GetSell（）函数中，您编写了：

Ask+(TakeProfit*Point)

它返回询问！因为您的TakeProfit已设置为零。如果您不想设置止盈，请输入：

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

这是新代码：

我在我的代码中对orderend和orderclose中的mql4有一些疑问
