I'm out of my league here when sle and Jacobsen check in with their insights.... but fwiw.... you're obviously new to this stuff ... bearing that in mind... I have no idea what the mechanics are behind paints like this but I can assure you, start paying attention because you will see these dozens of times/day on L2, especially in extended hours and on high-vis type stocks or stocks that just reported earnings. For the most part they will not trigger any stops you may have set. Its certainly a good question on your part though... it means you're serious in your endeavors. Kudos.
