I'm a long time thinkorswim user, but have heard a lot of great things about SC and so I'm running a trial now and comparing the two. Today I noticed some actual price differences between TD ameritrade data feed, Transact (my live account data feed), and the SC historical data feed. Notice in the attached image that the price on the ES today (9/15/14) at 9:39 EST shows a different high value between Transact (1975) and the other two (1975.25). I know it's only one tick but there are other price differences too and even just one tick could easily make a difference in the way that support/restistance is determined, etc. Why/how can these be different? And the big question, which one do I trust? Is there a definitive source that I should compare these three against to know for sure? Thanks!
