Yes, separating the winsock from the other file functions is what I had in mind as well - I didn't want to push my luck in directly asking for it though ;-)

As for winsock, I hadn't thought much of listening and receiving, because I didn't think it would be possible from MT. But if so, that would open up a whole new world of possibilities - controlling mt4 from outside. Sort of gets around the non-existent mt4 API issue???

Interesting thoughts. Thanks in advance for what you can do!
