I'd like to see better strike/expiry selection. I currently have to manually define my SPX strikes and expirations so I can keep the total symbols under control. I'd like to have some of these options: - Pick all strikes with open positions (I think it does this already but I have to test it and I don't want to mess up my manually defined strikes) - Instead of "Small" "Medium" or "Large" have something like pick all strikes within __% or ___sigma or __ strikes from the underlying price or perhaps a delta chooser (minimum of ___ delta) - Use user-defined strike separation (5, 10, 25 points etc) - Use calls, puts or both. Or only OTM options. - Pick which expirations to use. Show weekly, monthly, quarterly and LEAP expirations as check boxes and let you choose which ones to include. After the user has chosen the calculated strikes, let them add/remove strikes. For instance, if I only want to trade OTM puts and add a deep ITM call for an M3, let the user add some additional ITM call strikes. I'm sure this would take some work but improving the strike/expiry selection would help quite a bit, especially for underlyings with a lot of strikes and expiration.
