Want pro level charts for a modest fee?
Ensign. no backtesting/systems design stuff in it however. just pure charting that lets you do anything pretty much. And its fast as hell to change time frames, etc. one click. Instantaneous. none of this drop down menu crap. (although you can do things that way too).
QT and Sierra are good products if you don't need really high end stuff, and just trade a few instruments, but very lacking otherwise. there is a reason they are free or nearly so.
Ensign is $40 per month.
