What is IV Skew in Option Analytics, and how do I use it?

IV Skew shows how Implied Volatility (IV) differs across option strike prices for the same expiry. For example, one strike may have an IV of 19%, while another has 16%. This difference is called IV Skew.

In FYERS Option Analytics, you can view these differences in a single chart instead of checking each strike separately. This helps you identify which strikes have higher or lower IV.

  1. Log in to FYERS Web or the FYERS App.
  2. Go to Options → Option Analytics.
  3. Under Implied Volatility, select IV Skew.
  4. Choose your preferred underlying and expiry.

  3. Compare Call and Put Open Interest (OI) alongside the IV curve.
