I was really looking for answer with MT5, a bit different to MT4

I had read the link you provided previously. As MT5 addresses positions, deals and orders the terminology is confusing to me . Does int OrdersTotal refer to a single chart say eurusd with one or more posiitons each posiiton containing a number of orders, that is int OrdersTotal calculates/limits the total number of orders on that currency pair? If so that is not what I want.

In Toolbox I want only one position (which may contain one or more orders) for a single currency pair open at one time during the chart timeframe H1, H4 etc. No other cuurency pair positions can be opened during that timeframe.

It is my understanding that the user needs to have a defined list of pairs that cannot open positions concurrently. Is that correct?

Returns the number of current orders.

int OrdersTotal();

Return Value

Value of the int type.

  int basket=OrdersTotal(); //this is where your orders total value comes from, follow it up with a loop
  
  for(int x=0;x<basket;x++)
    {
     if(OrderSelect(x,SELECT_BY_POS)==false) continue;
     //Do some stuff here
     //You need to check for OrderSymbol() in this loop.
      
    }

It is my understanding that the user needs to have a defined list of pairs that cannot open positions concurrently. Is that correct?

Hi Professional4X,

Many thanks for your help, I was positive it could be done biy my developer was saying it is very difficult to do. My background years ago was fortran coding not quite the query languages of today. Your assistance is greatly appreciated particularly taking the time to write an example of the code that may suit.

Again thanks you have been most helpful

Is it possible in either or both of MT4 and MT5 for an EA to recognise that an order is open in terminal (toolbox MT5)?

What I am hoping to achieve is this. EA is on 8 charts if an order is opened on one chart I do not want the EAs on the other seven charts opening new orders until the current open order is closed. Is this achievable in an EA?
