Open trade and closing trade on reverse signal

July 8th, 2015, 01:22 PM

I am trying to write an EA using an indicator with icustom.

How can I get the EA to close an open trade when an alternate signal is fired. Also how can I send a market order on the next bar when the signal has fired.

extern double downtrend;
extern double uptrend;
input double lots=1;

int start()

{

int downtrend = downtrend=iCustom(NULL,0,"DayTrading",2,0);
int uptrend = uptrend=iCustom(NULL,0,"DayTrading",1,0);

if(downtrend)
{
bool ticket=OrderSend(Symbol(),OP_SELL,lots,Bid,0,0,0,"DayTrading",16384,0,Red);
}
else if(uptrend)
{
ticket=OrderSend(Symbol(),OP_BUY,lots,Ask,0,0,0,"DayTrading",16384,0,Green);
}
}

Thanks

Code

                            
extern double Lots = 2;

extern double Slippage = 2.0;

extern int    MagicNr=9502;



//+------------------------------------------------------------------+

//| expert start function                                            |

//+------------------------------------------------------------------+

int start()







 { 

  double ArrowUp, ArrowDown;

  static int iBuyTicket=-1;

  static int iSellTicket=-1;

  static datetime tCurTime;

 

  

  // Get Supersignal state

  ArrowUp = iCustom(NULL,0,"PZ_DayTrading",1,0);

  ArrowDown = iCustom(NULL,0,"PZ_DayTrading",2,0);

  

  // Open orders on new bar only

  if (tCurTime != Time[0]) {

    tCurTime=Time[0];

    

    // Open Buy order if previous bar has arrow up signal

    if  (ArrowUp!=1 && iBuyTicket<0) 

      iBuyTicket=OrderSend(Symbol(),OP_BUY,Lots, Ask, Slippage, 0, 0, 

                "DayTrade", MagicNr, NULL, LimeGreen);    

    

    // Open Sell order if previous bar has arrow up signal

    else if  (ArrowDown!=2 && iSellTicket<0) {

      iSellTicket=OrderSend(Symbol(),OP_SELL,Lots, Bid, Slippage, 0, 0,

                "DayTrade", MagicNr, NULL, LimeGreen);    

    }

  }

Now the EA opens various trades, it should only open a single position the bar after the indicator has signalled an arrow.

Also how do I close an open position when an opposite signal occurs.

Thank you all
