Hey Mustang, I had this problem as well - http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=445897#Post445897 - and it seemed to be occurring when I invoked the exitLong() and exitShort() functions. 'Stop' and 'Trail' exits worked fine.

It seems that the issue is now resolved, but I'd really like to know what was causing the problem in the first place, for two reasons:
1. To improve my own knowledge of how the MT4 plugin works; and
2. To have some idea of how to solve problems of this nature that might arise in the future.

JCL, any chance of enlightening us as to the details of the issue?

Cheers
