Hi PANTITS,
I don't know if I've interpreted your desire correctly, but it sounds like you wish to adjust the RSI indicator based on a volatility type indications, such as Standard Deviations. If I'm wrong I apologize for wasting your time, but Equis' best formula-writer wrote a Trader's Tip for an article in Stocks & Commodities Magazine some time back. I was able to find it by searching the magazine's web site. Here's the link:

Hope this helps.
