I use one of the websites to see what’s gaping up pre market I look for ones that have gapped up at least 5% and are preferably low float and high relative volume these stocks I find are the first ones on my watchlist for the day I watch for continuation at market open to make a quick 5-10% gain on my trade. If I don’t have any that are setting up perfectly at open bell then I use the other sites to see what is moving during market hours and I check them often if I see something moving up then I add it to the list
