I wouldn't agree that indicators are worthless. I would agree that believing that your indicator is telling you the "whole truth" is a less than optimal strategy.
I use two indicators ... I have emas on my main entry chart and I have the same emas plus a cci mapped onto my short term exit and "fine tuned entry" chart.
The emas are selected because over a long period of time (several years now) they have been support in weakly and strongly trending markets. Watch the markets: if you can find emas that create support in a trend and help you too see when the trend has changed then they are useful.
For me they help me see that a retracement is "sufficient" and thus likely to end before the "trend" resumes. They also help me see when the retracement is probably reversal but there is a mix of ema and price behaviour required to convince me of this.
The CCI I use for one thing only. I count short term thrusts and when the third thrust or one that corresponds with prior highs or lows is divergent I look for a price action based exit. Thats all ... it works for me.
Edit: The use of indicators doesn't preclude the use of price action/support resistance to fine tune entries. Also the CCI will show divergence not visible in pure price action because the CCI's normalizing function takes into account the recent range - but like everything in discretionary trading
you have to figure out what will work for you.
