Hi everyone,
I need a way to be able to scan and find those options whose bid-ask price spread for their ATM strike is within a narrow range, say 10 cents or less. This will help find those options with tight bid-ask price spread.

I have often wanted this. I just have created a watchlist of stocks that I know have a tight bid-ask spread.

aa, appl, Amat, amrn, amd, atvi, ba, bac, bidu, c, cat, cmg, cost, crm, caco, cvs, gdxj, dis, fb, Fdx, hd, intc, iq, m, mcd, mu, mro, nflx, nvda, pg, pypl, roku, sbux, spy, snap, sq, tlt, twtr, vxx, vz, wbc, wmt, x, xom, xop

Everyone that trades options on TOS needs this, but I don't think it is possible.

I have a script that works for a watchlist column but can't make it work for a scan. Maybe someone can figure it out.
plot spread = Round(ask - bid,2);
AssignBackgroundColor(if spread < 0.05 then Color.Dark_GREEN else if spread < 0.5 then Color.Dark_ORANGE else Color.dark_RED);
