technical analysis question - rsi, page-5

IMO Relative strength should be in the upper half - always. The best way to use it is to draw horizontal trendlines on the top and bottom and work from it that way to use it as an overbought/oversold indicator. So you could buy when it bounces off its bottom RSI trendline.

If RSI dips below a horizontal oversold support line, I would be questioning whether the uptrend is still strong.
