Price is pretty irrelevant, available supply doesn't mean a lot on it's own, but volume is really important.
There are two key things I look at in a newly added coin - the market cap, the volume . . . and most importanly market cap divided by volume. That really tells a story - I like something around a ratio of 100. You won't get this number on CMC, gotta do that in your script.
Where does a non tech person get and run a script like that ?
You'd have to hire someone if you're not technical. Or maybe I should sell mine.
Here's what I got on the last run a few hours ago. This is the kind of thing a script outputs

It's not a guarantee though - in fact I can guarantee some of these are dogs. It's just a starting point for research - you can't write a script for that.
