I always say that the volume between Forex brokers is relational. What I mean is that if you are using a fairly large broker or ECN broker then typically even though the volume amounts might be different between them the bars are relationally the same.
IE a no demand bar on one broker is typically a no demand on another broker.
The only times I find this might go awry is during what we call Dead Zones
(Lower than average volume/activity periods) but I would say you shouldn't trade during these periods anyway.
That said I find Broco (BrocoTrader Platform) to be an excellent source for volume as is FXPro and FXCM etc.
I would also like to mention that we are planning a stand alone version which will allow you to use multiple datafeeds (mt4, esignal etc) This will likely be a free upgrade for anyone using our current mt4 version.
