Each weekend I watch the relevant Youtube clips from FXEmpire.com to see their TA. They won't get me into a trade but if my analysis is the opposite of theirs, I will review my reasoning.
During the week I occasionally look at the TA by dailyfx.com in a similar way (they also give me a flavour of the fundamental factors they see as applicable, plus the economic announcements on the calendar).
I've just started receiving emails from Captain Currency to see how my system runs alongside his. Too soon to give a verdict on this.
Otherwise, I avoid anyone else's charts like the kiss of death.
