Have not tried it with larger caps, 10k fits for the smaller caps with % +- potential movement, stating the obvious you are looking for a gap down on open.

In saying that if you upped your transaction size from 10k to ? for the larger caps might work even better, don't know, I'm comfortable with 10k out of habit I guess.

Its something I have been doing for a decade, any time fear is around, the dow does not need to drop 2% for it to be viable.

Mechanical thing I guess, fwiw bit like seeking out 'shorted' stocks and banging them on your WL, get to know their rhythm over time, you know something IS going to happen, just not when, so there in lies the benefit.

Most times people run from 'shorted' stocks, 'dog its being shorted, run for your life' but there is money in doing exact opposite if you know what you are looking for.

In saying that some stocks are shorted because they are complete dogs but if you have spent anytime in market they are obvious.

Anyway just some thoughts, off to a BH 'work function', room full of fcking lawyers, rather roll in the hounds no2's for a couple of hours tbh.
