Don (and Dave),

This "pinch" in the Bollinger bands is merely an indication of a period of abnormal involatility. As most T/A are aware, a lack of volatility usually precedes a breakout in one way or another. I think (imho) that the key to determining the direction of the breakout is best left to the other technical indicators. As John Bollinger would tell you, his bands are formulated by calculating typically 2 standard deviations above and below a moving average (typically 20 day). As volatility decreases, the bands tighten.
