- You can not use any
Trade Functions until you select an order. If you already have one selected, why select by ticket? If it's a partial close thing, that comment is broker dependent.
- Not a good idea to use comments, brokers can change comments, including complete replacement.

Hi all, I have error 4051 with this code, could you help me? Thank you!
I verified by printing that the int "Old_Ticket" is correct, so I don't understand why it returns 4051 error.
