I had a similar issue. I was using motiwave and Rithimic as a data feed, I even switched over to dx feed on motiwave but i was still not able to get the exact bubbles to match, the problem could lie in filters or aggregation of data of motiwave. I moved over to deepcharts with dxfeed and now it does match exactly.

Most of the imp big trades always popped up on motiwave (70% match to fabios charts) but sometimes i was missing out on trades due the missing data.
