Symmetry break - I wonder what the odds actually are of a lower higher for given conditions (magnitude of break,  slope of trend, etc)?  Last time we had a symmetry break, the SPX was making new highs within two days.  Anyway, just another question I'll tee up to ask an AI when we get one that is trained on equity price data.  My guess is that some companies have already spent the big bucks to train their own AI on historical price data...but I can also see why they wouldn't release it to the public until it becomes less of an advantage.
