After a long time of being away from here, we are thinking of publishing our trading plans here every morning, again.
For starters, here's a very simple, actionable, but potentially powerful idea we are looking at for now:
Go short if SPX breaks below 4670 or 4660 with a trailing stop of 9 points - or, exit at 3:59pm (depending on your trading time frame, say 1M, 5M, 15M, 30M, 60M, your final results could be different from someone else).
