About the Diagonal Put Spread

The calculator opens with a diagonal put spread: the put at the next strike below the money sold in the nearest expiration and the at-the-money put bought in the next one.

It works like a calendar spread with a bearish tilt: the short near-term put decays faster than the long one, and the position does best with the stock falling toward the short strike by the near expiration. The chart models what the long put is still worth then.

Change the symbol, strikes, expirations or quantities, or add legs: the calculator takes up to eight option contracts and one stock position. To find candidates, use the Diagonal Put Spreads Screener: its chart icon opens this calculator with the selected position.
