Scanner Criteria for Gap strategy

[737ngx]

Hello All,

I have been playing with a free scanner at finviz.com, I am trying to set correct filters to identify possible useful stocks for this strategy, but I am not sure I do the right thing.

I set the price to under $5
I set Avarage Volume to Over 1M
I get Gap to ... start from Up 20% and lower it until I gat at least 5 stocks in the results.

Am I approaching this correctly?

Thank you
Nic
