I tried Localknowledge.com a couple of weeks ago for free (I lied about my e mail so I got like two or three weeks free) but there was this bug with software;
Say you are looking at 1 and 5min chart of ES02H and after a while you drag that little cube at the bottom and scroll left, than back right... and it messes up the chart like when your window on desktop freezes of leaves trails. Also every now and then it would snap back to beginning of the trading session all by itself for no reason and you would have to drag it back right to see the latest candles. Yes, and then you would have the problem of messed chart...
I e mailed tech support about that AND NOONE REPLIED!!! No way am I going with that software
