Orderselect - by ticket.

Hi all,

Trying to make some code that uses OrderSelect() to get the ticket number of the 2nd last order  that has been opened by my EA on the current pair. (EA has a magic number).

Looked around but everyone is just selecting the last order.

Thanks for any input.


Cheers

Richard

I don't know whether this is the simplest way, but it should work. I have not tested it.

//Function to find 2nd last order
 int Find2ndOrder()
    {
    int as=0;
    int ot=OrdersTotal();
    int ticketarray[];
    ArrayResize(ticketarray,as,ot);
    datetime datearray[];
    ArrayResize(datearray,as,ot);
    for(int x=ot-1;x>=0;x--)
       {
       if(OrderSelect(x,SELECT_BY_POS,MODE_TRADES))
          if(OrderMagicNumber()==MagicNumber)
             {
             as++;
             ArrayResize(ticketarray,as);
             ticketarray[as-1]=OrderTicket();
             ArrayResize(datearray,as);
             datearray[as-1]=OrderOpenTime();
             }
       }
    if(as<2)
       return(0);
    int index=ArrayMaximum(datearray,WHOLE_ARRAY,0);
    datearray[index]=0;
    index=ArrayMaximum(datearray,WHOLE_ARRAY,0);
    return(ticketarray[index]);
    }

 But at least it may give you something to think about. This obviously doesn't work with closed orders, you will need to modify if you need to include closed orders.

Hi GumRai,


Thanks very much - it appears to be working correctly on backtester. I'll test on demo to be certain.

Your a legend, exactly what I was looking for.


Cheers
