Gap up on volume scan

Gregory

How do you write a scan to scan for stocks that gapped up on their highest volume ever?

I don't think you can test for highest volume ever. But you could test for some very unlikely volume event, e.g.

and [volume > 1 day ago max(250, volume) * 5] // today's volume greater than 5x the largest volume in a year

Another idea -

and [volume > sma(250, volume) * 10] // today's volume greater than 10x the annual average daily volume

Gap up would be

and [low > 1 day ago high]

Perfect! Thanks.
