I've looked high and low and can't find an options scanner that scans specifically for butterfly spreads by P&L and allows me to change strike intervals. I found optionistics and it's close but is lacking some functionality that I'd like to have in a scanner. Even if it's an online broker that would be fine as I could just drop some money and open an account. ps if someone says TOS ... I think I'll pull my hair out.
so all you want is a scanner that lets you change strikes? you know a fly is just a spread between 2 verticals.
Scanning for fly risk isn't optimal. The debit is inversely proportional to vol, but where do you start as you can structure dozens of flies (5 wide to 50 wide). Mine top-decile tickers with IBTWS (IV or IV/SV).
