About the Diagonal Call Spread

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

It works like a calendar spread with a bullish tilt: the short near-term call decays faster than the long one, and the position does best with the stock rising toward the short strike by the near expiration. The chart models what the long call 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 Call Spreads Screener: its chart icon opens this calculator with the selected position.
