11.5 下单组件升级优化

继续优化下单组件,并封装buy和sell方向订单

在函数内部的变量或者函数名称,如果需要定义私有,那么前面定义_, 表示私有变量和私有函数. (快捷键: Shift + -)

// buy方向下单函数组件
bool Buy( const string symbol=NULL, // 交易品种 1
          const double volume=0.01, // 定单手数 3
          const int sl=0, // 止损价 4
          const int tp=0, // 止盈价 5
          const int deviation=5, // 滑点 6
          const string comment="", // 定单注释 7
          const ulong magic=8199231 // EA识别码 8
                  
)
{
  return PositionSend(symbol, 0,volume,sl,tp,deviation,comment,magic);
}

// sell方向下单函数组件
bool Sell( const string symbol=NULL, // 交易品种 1
          const double volume=0.01, // 定单手数 3
          const int sl=0, // 止损价 4
          const int tp=0, // 止盈价 5
          const int deviation=5, // 滑点 6
          const string comment="", // 定单注释 7
          const ulong magic=8199231 // EA识别码 8
                  
)
{
  return PositionSend(symbol, 1,volume,sl,tp,deviation,comment,magic);
}

double _valStopLossPrice(const string symbol, const int type, const int sl)
{
  if(sl <= 0.0) return 0.0;
  double ask = SymbolInfoDouble(symbol,SYMBOL_ASK);
  double bid = SymbolInfoDouble(symbol,SYMBOL_BID);
  double m_sl = 0.0;
  if(type == 0) m_sl = valStopLossPrice(symbol,type,ask,sl);
  else if(type == 1)m_sl = valStopLossPrice(symbol,type,bid,sl);
  return m_sl;
}

double _valTakeProfitPrice(const string symbol, const int type, const int tp)
{
  if(tp <= 0.0) return 0.0;
  double ask = SymbolInfoDouble(symbol,SYMBOL_ASK);
  double bid = SymbolInfoDouble(symbol,SYMBOL_BID);
  double m_tp = 0.0;
  if(type == 0) m_tp = valTakeProfitPrice(symbol,type,ask,tp);
  else if(type == 1)m_tp = valTakeProfitPrice(symbol,type,bid,tp);
  return m_tp;
}
