面向对象编程会让我们编写代码变得非常简单。
面向对象编程主要是要熟悉4个类库。
#include Trade\PositionInfo.mqh
#include Trade\Trade.mqh
#include Trade\SymbolInfo.mqh
#include Trade\OrderInfo.mqh
其中
PositionInfo 是持仓单信息 OrderInfo 是挂单信息 SymbolInfo 是品种信息 Trade 是交易类库
使用之前需要定义各种对象的实例
CPositionInfo m_position; // trade position object
CTrade m_trade; // trading object
CSymbolInfo m_symbol; // symbol info object
COrderInfo m_order; // pending orders object
交易之前在初始化函数里面要指定一些相应的属性
//---m_trade.SetExpertMagicNumber(m_magic); //指定魔术号
//---if(IsFillingTypeAllowed(SYMBOL_FILLING_FOK))m_trade.SetTypeFilling(ORDER_FILLING_FOK);elseif(IsFillingTypeAllowed(SYMBOL_FILLING_IOC))m_trade.SetTypeFilling(ORDER_FILLING_IOC);elsem_trade.SetTypeFilling(ORDER_FILLING_RETURN);
//---m_trade.SetAsyncMode(true); //指定异步模式有了这条可瞬时下单上万单m_trade.SetDeviationInPoints(m_slippage);
下面就不一一介绍了我给出一个挂单EA的全部源码可直接下载下去好好学习。 //------------------------------------------------------------------
