1. Jan 30th intraday data indicates an error in the daily chart's high. If the intraday high of 283.29 is correct, that is a breakaway gap on Jan 30, 2018.
2. On Feb 2, another breakaway gap occurred which is clearly visible on the daily of SPY and SPX.
From what I've read, the last time this happened was in the 1930's. DJIA fell over 80% and it took over 20 years to recover.
History tends to repeat itself, but not in exactly the same way/fashion.
