Hello
the idea is this :
only 1 trade per symbol allowed.
i use to do it like this:
int total = OrdersTotal();
if(total != 0 )
{
return(0); // dont trade
}
else
trade

but the problem is that i have other open position from manual trades\other EA
i need that the ea will open only 1 trade per symbol.

please help, thanks!

Use MagicNumber to identify the trades placed by your EAs. Read up on Magicnumber by our gracious Coder's Guru and you will have a very good idea on what to do.

Good luck.

ok, i have 666 as magic number to trades that open in the ea
is this code any good?

Code:

   if(OrderSelect(ticket, SELECT_BY_TICKET) == true) // open trades
   { 
   if(OrderMagicNumber() == 666){
   return(0);} // no trades
   }
else
trade

Again, do a search, I am sure you will find Coder's Guru's lessons. There is nothing better than learning how to do it right.

I am providing you with a subroutine that will count the number of trades for a given symbol and a given magicnumber. You can call that to find the number of trades, and if it is equal to or less than a certain number, you can place your trades.

PHP Code:


			
int CountTrades(int MagicNumber)

{

 int count=0;

 int trade;

 for(trade=OrdersTotal()-1;trade>=0;trade--)

 {

  OrderSelect(trade,SELECT_BY_POS,MODE_TRADES);

  

  if(OrderSymbol()!=Symbol() || OrderMagicNumber()!=MagicNumber)

   continue;

   

  if(OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber)   

  if(OrderType()==OP_BUY || OrderType()==OP_SELL)

   count++;

 }//for

 return(count);

}
