Hi @Naman @Dhan_Cares @PravinJ ,

If anyone can explain how ATM IV is calculated?

Waiting for the day when Dhan data can be consumed without comparing with any other reliable tools.

PS: Needless to say there is US CPI numbers coming today EOD.

Hey @amit, back when you were comparing how ATM IV shows up across platforms and asking how it is calculated, the missing piece was really a way to watch it move. That view exists now. The ATM IV Chart on Options Trader Web auto-tracks the ATM strike and plots its implied volatility against spot, live, with up to 45 days of history. You will find it under Insights, then IV Chart, on options-trader.dhan.co. Now that you can see ATM IV trend continuously, does it line up with how you expected it to behave?
