This mild weakness CO is more or less how things are rolling after the end of March breakout. The mild down opening after options expiration is theoretically bullish according to Investiquant. They are a major influence on my work. They keep track of events like that, performance on days of the week, etc. and give daily odds on futures.
I don’t bother looking at days as more than a consecutive series. What they do is more work and kind of against my design philosophy; I’m not finished with whatever I’m doing now. Their approach has merit. They generally have two youtube commentaries; before the open and around 2.
Their work is centered around trading futures during the 9:30 to 16:15 ET hours.
I also consider this morning bullish, but through the framework of studying CO/OC action.
