level 1 bid and ask spread scanner

Hi Pete is there a way that i can only scan stocks that level 1 bid and ask spread that only range 1-5 cents.

I found this watchlist column script on TOS but i have no luck changing it in scanning less than 5 cents spread stocks.

plot spread = ask – bid;

AssignBackgroundColor(if spread < 0.05 then Color.GREEN else if spread > 0.06 then Color.YELLOW else Color.RED);
