Why there is same IV for put options and call options in zerodha options chain

In the Zerodha option chain, the Implied Volatility (IV) is often shown as the same for both call and put options at the same strike price. Because of this, it becomes difficult for traders to gauge the real market direction using IV.

Sometimes, changes in IV provide useful signals about market sentiment whether the market participants are expecting a bullish or bearish move. However, when the same IV is displayed for both calls and puts, it reduces the clarity needed to interpret these signals effectively.

For active traders, especially those who rely on option data for directional bias, it would be very helpful if separate IV values for call options and put options were displayed. This would allow traders to better understand where the volatility demand is increasing on the call side or the put side and make more informed trading decisions.

Providing more detailed IV information in the option chain could significantly improve analysis for option buyers and sellers, and help traders better interpret market expectations.

Sensibull has a write-up on it:

Kite is most certainly doing the same. :kite:
They have designed the IV calculation to be theoretically correct and not be influenced by wide bid-ask spreads, but such a calculation is quite useless for intraday trading. :face_exhaling:

Ideally, there should be a setting to let the user choose if they want a nice-looking but incorrect IV or the real thing. :wrench:

It’s like Heikin Ashi but for IV and there’s no way to change it! :sob:
