2 cents
I've demoed Sierra, as thought to use that for advanced charting, do you know why I dropped that idea
just because 2 times (it was enough for me) I've installed that into my machine that software was installed not to as per specified by me folder, but at C and a lot of it folders spreaded sporadically here and there, well I'm not pro programmer to search for all modules of program installed in order to safe it from "cleaning" and anti-virus programs and also what is more important to me with Ninja I just found and set all I need literally in seconds max minutes since downloading and you know may be I really stupid, but in Ninja I can find how to switch 5 min timeframe to 30 min in Sierra...well:crap: I still can not find it, at least within 30 seconds + for example drawing tools, Ninja has it not quite amongst better, but still you can more or less promptly and comfortable manage it, but with Sierra...:helloooo:
Well, what I want to say I kept Sierra in mind for charting and honestly tried it, but even having IQ above 1.0 not succeeded + having 2 live datafeeds available amongst supported by Sierra I nevertheless had 8 time bad efforts to establish it however acted as per Sierra manuals.
My conclusions (only mine) if I want to play Lego I will choose Sierra, if I want to have stable and reliable charting software I will not choose it even for historical data (the main...programs shall serve you, not you them)
