Trending vs. Chopping

Bollinger bands might work as well. Once they bands are narrow you know you reached a ranging period. Wait for the breakout in the direction of the main trend.
 
OxfordStrat - The inference behind your question is that you have a large number of charts to compare in order to select targets for trades. If I'm right, are you happy such a large range is really optimum?
 
Zoom the chart right out so you cant see the individual candle colors and... um... look at it.
