Samsara, I've made good money by simply using yahoo charts. l.o.l. ok, that's a bit too much.

this is the one I frequently use:

www.prophet.net  

Their java chart is really good. I've seen Realtick's charts and I doubt if there's anything in the world that beats them. But for a free version, prophet's charts are like RealTick's charts compared to other free ones.

I personally stay away from much of technical analysis. I usually download data and do some of my own voodoo on them. Makes me feel like a freakin quant.

The trend lines and price volume information are my best friends, ALWAYS!!!

And give QT a try.
