Hi, I'm looking for a basic options screening software. i'm interested in seeing how the daily options volume compares to its Avg options volume on individual stocks. Also interested in comapring the put/call ratios to its avg put/call ratios for individual stocks. i can find basic screens on yahoo to look for individual options with high volumes but i would like to compare it to the stocks avg options volume (20 day or 50 day avg). Same for put/call ratios. Any reccomendations?
