you have to grab (i.e. Select) the order, either by looping through the pool of orders, or if you know the ticket, use something like....

  if(OrderSelect(555, SELECT_BY_TICKET)==true)
    {
     Print("Order #555 lots: ", OrderLots());
    }

Good Luck

thanks you barrowBoy.

what I don`t understand is why it is necessary to select in first the order in the pool of order.

we can`t use something like this: OrderLot (555, SELECT_BY_TICKET)

It meen that the terminal cannot instancy all the variables of all the pool of orders in the same time

or that mql4 is not able to read them simultaniously to the terminal indeed?

thanks in advance.

To do so would be a big memory overhead.

Keep in mind that MT may be running many EA's and you can have many instances of MT connected to different accounts & brokers all on the same machine.
