Meta Trader 4 和 5 代码无法正常工作并且无法打开 Buy Sel Trade

Question

我有这个 MQL4 代码：

我开发了它，然后在线阅读资源和帮助小组并修复了错误。

现在它给出了 0 个错误和 0 个警告，但仍然没有按预期工作：

根据 MQL4 机器人，其工作并打开买入/卖出，但始终为 0 利润。

根据 MQL5 机器人，它不会开启任何买入/卖出交易。

我的代码有什么问题吗？

Answer 1

尝试在 Buy 和 Sell 的 OrderSend 函数中使用要价和出价，而不是“currentPrice”，如果您没有通过使用 OrdersTotal 函数给出 if 条件来限制订单数量，则此代码将继续发送订单。 例如： if(OrdersTotal() == 0) { 您的 OrderSend 函数在这里。 }
