Hello, i wrote my EA. now to finish it i need just to count how many lots is used total from active orders. So maybe you have ideas what function should i use to get the total lots used at the moment from active orders.

for exmp.

order nr:

1.0.01

2.0.02

3.0.03

4.0.05

so i need a sum of all theese, i need to get 0.11)

exmpl;

double usedlots = ???(help) ;

if(usedlots == 0.11)

then = dothat;

else

nothing;

Thank you, i hope you understand :)

Loop through the open orders, OrderSelect() one by one, check Symbol() and Magic Number if applicable, keep a running total of OrderLots() for the orders that match Symbol & Magic Number. Done.

If there are no way to "select all" function at orderselect() becouse, every time is unique and the number of order will not be the same, my ea working with the 10-30 orders in a day, so i have to count the lot size every new bar. If i should use orders numbers i would need to edit my ea everytime :/

Maybe you can get someone to code it for you . . . I won't.

I'll try to help once more . . .

<pseudo code start>

Loop through the open orders by position. Read here and here

If an order matched the Symbol you want and the Magic Number you want

add iit's OrderLots() to a running total

When the loop is complete your running total is the total number of lots in all your open Orders.

<pseudo code end>

```double totalOpenLots = 0;
for(int iPos = OrdersTotal()-1; iPos >= 0 ; iPos--) if (
OrderSelect(iPos, SELECT_BY_POS)                    // Only my orders w/
&&  OrderMagicNumber()  == Magic.Number                 // my magic number
&&  OrderSymbol()       == chart.symbol                 // and my pair.
){  totalOpenLots += OrderLots(); }
```
