Although you don't see a million on my charts, it is important to use a million indicators (or five or six). I like to think about it like lovers, the more you have... the more they will all agree with one another.
When I'm making larger plays, I make sure that NOT JUST ONE, but multiple indicators agree with my predictions. Here are some of my favorite indicators.
Parabolic SAR (when a large trend begins it usually creates the beginning of a parabolic curve in this indicator, the same is true in the inverse) investopedia.com/terms/p/parabolicindicator.asp
Chris Moody's MACD (An incredibly useful trend indicator. I've stripped it down (located in the top pane) so that it only shows me the essential trend changes. This one indicator could make you money all by itself. You are a genius, Chris.)
THE FOURTH PANE HAS A STACKING INDICATOR I FOUND THAT PUTS MANY TOGETHER (Thanks Sigma Draconis) RSI / Stoch / SRSI / MFI / Aroon Overlay [SigmaDraconis]
