I am in the process of developing a signals service. Before the MT4 600 build the Master EA was able to send trading signals to the SLave EA between two different computers located in two different places. However, this has stopped working after the MT4 600 build upgrarde. The relevant changes have been made to the codes and to connect to the diff database structure but it seems it is working on 32 bit but not on 64 bit OS for Win 7.
Is there any known problem of MT4 not functioning properly on a 64 bit Win 7 machine ? Can you please advise what needs to be done to fix the problem.
How do you connect the Master and Slave?
Probably it is that you have to use Windows' wide-functions?
