When the day's low is the opening price, every trade of the session happened at or above the open: not one seller managed to push it lower, even for a minute. Intraday traders run this as the OHL strategy at 9:20; on daily bars it reads as a conviction stamp on the whole session, and the ones that also closed up more than a percent are where that conviction paid.
