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
