Look at the all time VIX chart & for each year in January, see how it goes up with alarming regularity?
If I was going to short a US market I'd be taking a position around 19th Jan next year before the traders come back from their Christmas holidays.
Feb is historically one of the two worst months of the year along with September (after their Summer holidays).
So if the market wobbles between 19th Jan & the end of the month history shows it'll keep going into February.
Other than taking a position for September I personally think trying to time a short position into the market is a folly, unless the markets have already started to correct & you just go with the strong established trend (e.g Mar 20).

Using short term charts to predict the markets that are so easily impacted by macro factors & global events is no better than using a 'system' at Roulette.
It'll end in tears eventually.
