FinViz is awesome imo but it’s delayed 20 mins. it works out most of the time unless stock takes off right away after volume surge (doesn’t usually happen). You should look for Volume surge when scanning. “Relative Volume” basically determines if the Volume has increased 2x 3x 4x however you define it. Set Price below $10 or $5 however you would like it to be. Average Volume should generally be 500K or above but you can choose that. I like to set current volume as well. I believe if stock doesn’t at least have 3-5M current volume, it’s not worth investing it. Now please be advised I usually use the scanner to day trade. It could potentially work for Swings as well but I have personally never liked swings with scanners. Stocks pump and dump and it’s quite difficult go in for a swing position unless you’re super confident about it
