A big move is coming in the $SPX as the daily Bollinger Bands are tightening. Which way will it go? Based on simple symmetry, a breakout of the 3185-3005 zone targets 3365, whereas a breakdown targets 2825 (blue arrows). TBD, but stay alert. #trading #investing $SPY #stockmarket https://t.co/ePu0NsGBWE
