You seem to have a hard time understanding what a market is. This might explain why your models are so bad.
Hard to say where support is. Probably 1872. 1942 is some sort of support, and so is 1950, but all those are minor, imo.
Consider that Blackest of Mondays during 1987, the market started out similar to this, with two prior days almost identical. During the day, the futures were down, hold on to your ass, 30%. Today, that would be 590 shaved off the SPX. Locked Limit would make that impossible today. But -150 is not out of the question.
