Nifty will remain closed on 20th Oct on account of Dusshera
The levels for 21-Oct-26 are as follows:
Steps:
1. Look at the ATM IV of next weeks expiry and divide the average by 15.87 (sqr rt of 252 days) because IV projects yearly volatility
2. Add the % result to current spot price to get projected high
3. Subtract the % result from current spot price to get projected low
4. mark 50% of the % result for important up/down move from projected high/low
Example:
Nifty spot closed at 22888 on 19-Oct-26
The ATM IVs of the next week expiry of 27-Oct-26 is as follows
11.07 + 11.19 + 14.17 + 14.15 = 50.58 / 4 = 12.64/15.87 = 0.79% ( this is step 1)
Step 3 : Projected Low = Nifty spot - 0.79% = 22888 - 0.79% = 22707
