I don’t know if this is already known. But, I found a way to get MT4 to run on more than one screen. It happened by mistake and impatience this morning. I went to open MT4 and ended up clicking the icon really fast like 4 or 5 times. The next thing I knew, I had MT4 open twice! I tested a trade and there was no problems. I closed both instances of MT4 and tried it again. This time I let it open once and waited a few seconds before I tried to open it again. This time it did not work. I figured at this point it must only open twice if you click the icon rapidly like I did before. So, I closed down the one instance and rapidly clicked the icon again (probably 6 times in 1 or 2 secs) and it worked again!
I am sorry if this is already known. But, I have never heard of this before. I hope this helps.
Yes, it is my first post as I am not very social.
I am using FXCM’s MT4 if that means anything.
