The ATM IV Chart shows how the At-The-Money (ATM) Implied Volatility (IV) of the selected underlying changes over time, alongside the underlying price.

It helps you track volatility behaviour at the ATM strike during the trading session.

This is an analysis-only chart and does not allow order placement.

What does the ATM IV Chart display?

The chart plots multiple data points over time:

• ATM IV
  The implied volatility of the current ATM option
• Underlying Price
  The spot/index price at the same time
• ATM Strike
  The strike price was considered ATM at that moment
• ATM Straddle Value
  Combined premium of ATM Call + ATM Put

All values update dynamically as:

• Price moves
• ATM strike changes
• Time progresses

How is the ATM strike determined?

The ATM strike is automatically selected based on the underlying price at each time interval.

As the underlying price moves, the ATM strike may change, and the chart reflects this automatically.

No manual strike selection is required.
