Ann: Exploration Update - Drilling to Resume this Month, page-109

I was referring to the 50% line on the 14 day Relative Strength Index (RSI) (lower chart). Upper and lower 25th percentiles (or so) indicate overbought and oversold respectively. Between 50% and about 75% tends to indicate a confirmed uptrend. Converse applies for between 50% and about 25%. At least that's how I use it. The other useful thing is how it often predicts a trend reversal by topping/bottoming out on the wave preceeding the price top/bottom. Good for timing entry and exit. It is pretty much my preferred indicator along with volume.
