Find the Best Calendar Automatically

The pair map evaluates every possible front/back combination and scores them by IV ratio, DTE gap and quality. The best pair floats to the top.

Understand Term Structure State

Contango or backwardation at a glance — with the magnitude quantified. Steep contango favours selling calendars; backwardation favours buying.
