After hours scan

[Mart1]

I haven't been able to find a simple after-hours scan. Wanting to do something like this:
plot ah =(high - close) / close * 100;
where high is the highest trade after-hours, and close is today's closing price (4pm EST). TOS seems to pick up the regular hours high and yesterday's close.
Any suggestions?

Someone on YouTube posted a method of doing an after hours scan. Maybe this will help you.
