Where do I go about finding the website or software package that ranks daily the stocks with the highest extremes in price difference for ATM puts versus ATM calls. All available option months would need to be included in the rankings regardless of the options time length. Google is at 300. The 3 month ATM 300 puts are 20pts and the 3 month ATM calls are 32pts. What would have found this and ranked it for all other stocks.
