 checking the gappers on the stocks. I want to find the highest percentage gainers on the day every single day. Now, the reason why I look for the highest percentage gainers on the day is because these are the stocks that have the most range. These are the stocks that are up the most. If they're up the most, they have room to contract back down. If a stock is only up a dollar a share, maybe it comes down 50 cents a share. But if a stock is up 30 dollars a share, it'll come down maybe 15 dollars a share. You know what I'm saying? So number one, step one is finding the highest percentage gainers on the day.
