Thank you!

Well, apparently not...

Can you tell me why this script does not delete all orders, there are 3 pending orders in total in the terminal, but the script only deletes 2.

for(i = 0; i < OrdersTotal(); i++)
     {
     ticket = OrderGetTicket(i);
     Alert(ticket," ",i);
     if(ticket > 0)
       {
       trade.OrderDelete(ticket);
       }
     }

Because of the condition.

i < OrdersTotal(); 

You have Alerts there - see what it shows.

What's wrong with this condition, can you elaborate?

[Olegs Kucerenko]

int total=OrdersTotal();

for(i = total; i > 0; i--)
     {
     ticket = OrderGetTicket(i);
     Alert(ticket," ",i);
     if(ticket > 0)
       {
       trade.OrderDelete(ticket);
       }
     }

sovetnikmaker: What's wrong with this condition, can you tell us more about it?

Look at the description of the for statement and try to answer two questions:

1) how often is the condition I specified checked in the loop;

2) what values is returned by the function OrdersTotal() at each check of the condition "i < OrdersTotal()" (taking into account that the body of for statement itself contains code for deleting an order).
