OrderSend - comment

[[Deleted]]

Hi

The MQL4 documentation states under OrderSend():

comment - Order comment text. Last part of the comment may be changed by server.

What does "last part" mean?

If I pass a 4 character string, does the server then "maybe" change e.g. the last 2? Or does it ALWAYS just append after the 4 characters?

Thanks in advance

I don't know for a fact but I assumed that if the comment could be 20 characters and you used 18 and then broker wanted to add 5 then 3 of your comment's characters would be over written.

The brokers can do nothing, add characters, or completely replace the comment.
