Since posting this, the market has ratcheted up a few points. No panic short-covering yet. Now I'll watch SPX 930 to see if there's a breakout. The market could crawl along that upper edge on low volume (possible headfake signal). It may or may not break above 930. If it does, then expect explosive volume and panic shortcovering.
That's where I see a short-term opportunity to take a short position. Not recommending anything. Just what I see.

In previous post, said 820 and 815, meant 920, 915.
