Diagonal Spread with Calls Option Strategy

Combines two calls that differ in both strike and expiration: a longer dated call at a lower strike is bought and a shorter dated call at a higher strike is sold against it, so the short leg can be rolled repeatedly while the long leg stays in place.

Last price and fifteen day volatility of the underlying are pulled in, since the volatility level at entry affects how the two expirations are priced relative to each other. Enter strikes, expirations and premiums to see the net debit and the position at the near expiry.
