I'm trying to figure out which brokers' version of MT4 I should use, I've got FXCM and FXpro ones installed and wondering which one is more 'accurate'? There are obvious differences I have noticed, notably minor price differences but the bars can be different as well, but the main thing is the volume at the bottom, FXCM has more drastic changes compared to FXpro, would it make much difference?

Note that I'm well aware of VSA, that's why I asked this question, also if there are other brokers' MT4 program to use which would be better for that purpose, I would be glad to go with your recommendation too.
