Ratio Spread

A ratio spread buys one option and sells more than one at a further strike in the same expiration, commonly one long against two short, which leaves the position net short options. The extra short contract funds the trade and widens the zone where it profits, but it also creates exposure beyond the short strike that the long leg does not cover, and on the call side that exposure has no upper bound.

Every leg prices from an option symbol built out of your inputs, with bid, ask and previous close pulled on demand next to the underlying's last price.
