Average Daily Ranges

I am trying to find out the Average Daily Ranges for the various markets for example ES, YM, Euro, Gold, Russel and anything else you might care to trade. The object is to find out which markets range better than others and to find the best daily ranges within those markets., particularly daily ranges.

Put on ADR indicator on your chart and your set to go.

I realised that ATR would give me that but hoped that some of the more enlightend and experience among the throng might have an idea of which markets might be more trendy, and have sufficient liquidity. The idea being if Corn for example was a trendy market with enough points per contract to extract say 20% of that days move .... You know where I'm going with this. Hope you can help.
