Well, not that new but I refrain from trading the open and usually wait at least 5-10 minutes and sometimes longer before I pull the the trigger. Works very well. I looked back at my days which were losses and the losses usually occurred the first 15 minutes of trading. Unless something looks explosive, i ignore the open.. Remember, Im just a bathroom attendant but I can trade. Anyone need a breath mint or a towel to dry their hands?
This dubious concept is only for day trading. I mean swing traders ignore opens and closes lol. By the way, all the action happens between open and 10:00 a.m. if 0 DTEs tell you anything.... Sometimes you get a push at the end of the day.
