checking the number of Lot's

you should use

OrderSelect() & OrderLots()

Thanks giol,

Like this?

Magic=1234;

if(OrderSelect(Magic, SELECT_BY_TICKET)==true)
    Print("lots",OrderLots());  
       else
          Print("OrderSelect returned error of ",GetLastError());

if 1234 is your ticket no., yes

It did not work, It´s showing: ERROR 0. It only works when I change the magic number for the ticket number.

I need to know the number of lots of all positions opened by the same expert.

Thanks again

I found my mistake. The looping was missing.

                        for(int i=1; i<=OrdersTotal(); i++) 
                        {      
                           if (OrderSelect(i-1,SELECT_BY_POS)==true)
                           Lot = Lot + OrderLots();
                        }

i told u that is working only if 1234 is your ticket no.

this code:

                        for(int i=1; i<=OrdersTotal(); i++) 
                        {      
                           if (OrderSelect(i-1,SELECT_BY_POS)==true)
                           Lot = Lot + OrderLots();
                        }

It is better to add for "buys" and substract for "sells".

if ( OrderType() == OP_BUY ) { Lot += OrderLots(); }

if ( OrderType() == OP_SELL ) { Lot -= OrderLots(); }

Then it will give you the correct idea.

I do not understand what you're want to get, you need to know the sum of all the lots, or all buy's or all sales, explain.

I already got what I needed. It was the total number of lots generated by one expert for one currency. I need this to close all my positions when the market's scenario changes.

for(int i=1; i<=OrdersTotal(); i++) 
                        {      
                           if (OrderSelect(i-1,SELECT_BY_POS)==true)
                           Lot = Lot + OrderLots();
                        }
