Check if Order of Symbol is already open

[Mitch Zanting]

Hello everyone,

I'm looking for a check function, So the EA checks if a trade of the symbol is already open and if its open already then dont open a second one.

I use the Orderstotal() at the moment but then i cant open more trades from different symbols.

   if(RSIValue<23 && OrdersTotal()<1){
   int buyticket = OrderSend
   (
      Symbol(),
      OP_BUY,
      LotSize,
      Ask,
      2,
      Ask- 250*_Point,
      Ask+1200*_Point,
      NULL,
      0,
      0,
      Green
   );

Here is a small piece of what im talking about.

Im looking for a replacement for the OrderTotal function.

So it doesnt check the whole Tradelist but only for the Symbol it active on.

Hope you all understand what im saying and i really appreciate if you want to help.

Regards,

1. Why did you post your MT4 question in the Root / MT5 EA section instead of the MQL4 section, (bottom of the Root page?)

   Next time post in the correct place. The moderators will likely move this thread there soon.

2. Using OrdersTotal directly and/or no Magic number filtering on your OrderSelect loop means your code is incompatible with every EA (including itself on other charts and manual trading.)

3. Using Point means code breaks on 4 digit brokers, exotics (e.g. USDZAR where spread is over 500 points,) and metals. Compute what a PIP is and use it, not points.

As one of ways:

extern int EAMagic = 777888; //EA's magic number parameter

int CountSymbolPositions=0;
 
  for(int trade=OrdersTotal()-1;trade>=0;trade--)
    {
      if(!OrderSelect(trade,SELECT_BY_POS,MODE_TRADES))
         continue;
      if(OrderSymbol()==Symbol())
         {
         if((OrderType()==OP_SELL||OrderType()==OP_BUY) && OrderMagicNumber()==EAMagic)
         CountSymbolPositions++;
         }
    }

//And then - your code, for example

if(RSIValue<23 && CountSymbolPositions<1){
   int buyticket = OrderSend
   (
      Symbol(),
      OP_BUY,
      LotSize,
      Ask,
      2,
      Ask- 250*_Point,
      Ask+1200*_Point,
      NULL,
      0,
      0,
      Green
   );
}

Alternatively...

bool trades_on_symbol(string symbol)
{
   for(int i=OrdersTotal()-1;OrderSelect(i,SELECT_BY_POS);i--)
      if(OrderSymbol()==symbol && OrderType()<2)
         return true;
   return false;
}
