Quote from TL Trader:
You'll get a lot of different opinions and ultimately of course you'll have to decide for yourself. I've read time and again that very very few successful professional traders use "indicators" (RSI, MACD, STOCHS, CCI, ect.). No doubt somebody somewhere is successfully using them. Personally I think you would be better off in the long run if you concentrate on simple price and volume action.
Paul Rotter says he uses CCI. Whether he actually DOES or not is another question.
Some things are worth repeating.
