How to have only one open trade at a time?

[[Deleted]]

Hi, My expert advisor is based on such a strategy that it opens a new trade on every single bar.What should i do to my ea so that it opens a new trade only when the previous trade is closed according to the closing strategy..........Thanks alot in advance !

int start(){

//manage open orders here

if (OrdersTotal() > 0){
      return(0);
}

//open new orders here

}

or a with a bit more control

int start(){

//manage open orders here

if (getOpenOrders() > 0){
      return(0);
}

//open new orders here

}

int getOpenOrders(){

   int liOrders = 0;
   for (int i = 0; i < OrdersTotal(); i++){
     if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES) == false){
       continue;
     }
     if (OrderSymbol() != Symbol() || OrderMagicNumber() != /*your magic number*/){
       continue;
     }
     liOrders++;
   }
   return(liOrders);
}

innovativebug:

you should start using Magicnumbers other then 0 like:

extern int MagicNumber = 34474212;

simpy copy&paste Russells code to the end of your code like here:

int getOpenOrders(){

   int liOrders = 0;
   for (int i = 0; i < OrdersTotal(); i++){
     if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES) == false){
       continue;
     }
     if (OrderSymbol() != Symbol() || OrderMagicNumber() != MagicNumber){
       continue;
     }
     liOrders++;
   }
   return(liOrders);
}

and you must limit all ENTRY signals with getOpenOrders() function like:

   //Buy
   if (Order == SIGNAL_BUY && ((EachTickMode && !TickCheck) || (!EachTickMode && (Bars != BarCount))) && getOpenOrders()==0) {

   //Sell
   if (Order == SIGNAL_SELL && ((EachTickMode && !TickCheck) || (!EachTickMode && (Bars != BarCount))) && getOpenOrders()==0) {

thats it

@ fx1.net......i did the same just what i was told by you....The ea works but it reacting the same way as it use to work before i.e opening and closing trade on everybar (Backtested) :(

innovativebug:

- do you have multiple symbols on same EA?

- did you change MagicNumber as i mentioned?

Its impossible that it open a trade without closing previous if you have done it properly.

Mate,  I am using own EA on multiple symbols...  ex)  GBPUSD, EURUSD, USDJPY  etc..

How can I open only one trade  ??

for example,

If my ea open trade on GBPUSD,   stop open other multiple symbols  until close the previous order(GBPUSD)

Why are you responding to a 10 year old thread?

The answer is simple. Don't open any trades when a trade of any symbol  is already open.
