52 Week lows Scans

I've been getting good expectancy with 2 52 week low scans. One filters for gap downs. Both I look for low RSI atleast below 75. I've found a lot of these low RSI's to have red days even when the overall market is green. Some can bounce back really hard and run though when the market is green some days. I've been selective about which I hold overnight and the whole day.
