Close Orders By Target or Cut Loss - MetaTrader 4のためのエキスパート

extern    double         inTargetProfitMoney     = 10;       //Target Profit ($)
extern    double         inCutLossMoney          = 0.0;      //Cut Loss ($)
extern    int            inMagicNumber           = 0;        //Magic Number

When this EA is executed, it will first call the OnInit () function. Where we will verify the input and variable initialization

int OnInit()
  {
//---
   if(inTargetProfitMoney <= 0)
     {
      Alert("Invalid input");
      return(INIT_PARAMETERS_INCORRECT);
     }

   inCutLossMoney = MathAbs(inCutLossMoney) * -1;

//---
   return(INIT_SUCCEEDED);
  }

And every time the price movement (tick) will call the OnTick () function

void OnTick()
  {
//---

   double   tFloating = 0.0;
   int tOrder  = OrdersTotal();
   for(int i=tOrder-1; i>=0; i--)
     {
      if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
        {
         if(OrderMagicNumber() == inMagicNumber)
           {
            tFloating   += OrderProfit()+OrderCommission() + OrderSwap();
           }
        }
     }

   if(tFloating >= inTargetProfitMoney || (tFloating <= inCutLossMoney && inCutLossMoney < 0))
     {
      fCloseAllOrders();
     }

  }

In the OnTick function, it will continue to calculate the total profit or loss. Then will close all orders that can be fulfilled the target or maximum loss limit

void fCloseAllOrders()
  {
   double   priceClose = 0.0;
   int tOrders = OrdersTotal();
   for(int i=tOrders-1; i>=0; i--)
     {
      if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
        {
         if(OrderMagicNumber() == inMagicNumber && (OrderType() == OP_BUY || OrderType() == OP_SELL))
           {
            priceClose  = (OrderType()==OP_BUY)?MarketInfo(OrderSymbol(), MODE_BID):MarketInfo(OrderSymbol(), MODE_ASK);
            if(!OrderClose(OrderTicket(), OrderLots(), priceClose, slippage, clrGold))
              {
               Print("WARNING: Close Failed");
              }
           }
        }
     }
  }
