# Term Structure Richness

> This endpoint returns the term structure richness. The "Term Structure Richness" is the relative "level" of the Contango or Backwardation shape. A reading of 1.00 would be a perfectly flat term structure - as measured by our method - while readings below/above represent Contango/Backwardation respectively. Using the term structure levels enables us to quantify how extended the term structure pricing currently is, at any point in time. The calculation take a ratio of 10-day ATM IV versus, 21-day, 63-day. 84-day and 189-days.
