Straddle Calculator

GammaWins' Straddle Calculator allows you to visualize the P/L and Greeks of straddles on US equities at any time before expiry, as well as over time for a fixed price of the underlying. The charts get updated as you modify the trade.

You can use the volatility skew and term structure charts to see where the options volatility level is compared to one year of history. Alternatively, you can use the free implied volatility history to see the ranges instead.
