EA Error

JSJTradeworx 2022.11.09 18:13

This EA must Open 1 Market Order upon Initialization, and the fill a grid with Pending Orders. SO now, upon Initiation, it opens multiple Market orders, and no Pendings. I get no error when I compile but it just does not do what I want. I am new to coding, if someone can just point to my mistake, I can find fix.

Thanks

```
  double   price = (InpType==ORDER_TYPE_BUY)?
```
Invalid constant. Order Properties - Trade Constants - Constants, Enumerations and Structures - MQL4 Reference

      if(!OrderSelect(i, SELECT_BY_POS))
         break;
      if(OrderSymbol()!=Symbol() && OrderMagicNumber()!=MagicNumber)
         continue;
      if((OrderCloseTime() == 0) && OrderMagicNumber()==MagicNumber)

Drop the second IF. You will never find a closed order (OCT!=0) in the loop.

         if(OrderType() == OP_BUY||OrderType() == OP_SELL)
            cnt = 1;
         if(!(OrderType() == OP_BUY||OrderType() == OP_SELL))
            cnt = 1;
        }

The function will always return one.

JSJTradeworx: it just does not do what I want.

Use the debugger or print out your variables, including _LastError and prices and find out why. Do you really expect us to debug your code for you?
