Strip Straddle

Doubling the puts turns a straddle into a strip: two puts and one call at the same strike and expiration, a long volatility position that pays roughly twice as fast on a decline as on an equal sized rally. The total premium paid is the most that can be lost.

Strike and expiry inputs produce the three option symbols, with bid, ask and previous close fetched on demand and the underlying's last price shown alongside, so the debit and the asymmetric breakevens recalculate whenever the quotes move.
