Hi profitplease, on the weekend if you have time could you give me a quick lesson on how to set up a volume scan or direct me to one that is already set up. . I was using day trade scans and found them very useful as they were live /5 minutes behind the real movement. I am using NAB trade and they have a top 20 movers but it only covers blue chip and not small caps.
