MT5编程，有两种方式，一种是函数式编程，一种是面向对象编程。

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。
