Nifty Expiry Today: Where the Index Stands at 10:11 AM

Nifty expiry today: measure	Level	Comment (my calculation where marked)
Nifty 50 previous close (26 Oct)	22,753.20	Up 153.20 points, or 0.68%, and the close of a four-session losing streak
GIFT Nifty (early morning)	About 22,663 to 22,672	Down about 81 to 110 points on different bases
Nifty 50 at 9:22 AM	22,671.55	Down 0.36% soon after the open
Nifty 50 at 10:11 AM	22,787.55	Up 34.35 points, or 0.15%, from the previous close
At-the-money strike	22,800	Nearest strike to the spot
Lot size	65	Per the option chain
India VIX (previous close)	17.16	Up 1.78%, per a morning note

The opening call was negative, and the index did dip, but it recovered more than 115 points from 22,671.55 by 10:11 AM (my calculation). That recovery is why Nifty expiry today has started on a firmer note than the GIFT Nifty signal suggested. Nifty IT was the weakest sector at 9:30 AM, down 1.7%, while the Midcap 100 and Smallcap 100 were up 0.29% and 1.34% at the open.

In plain words, option writers are selling calls around 22,800 to 23,000 and puts around 22,500 to 22,700, which marks that band as the zone they expect the index to stay in on Nifty expiry today.

What Can Move the Nifty on Expiry Day

Nifty expiry today: trigger	Detail	Why it matters
US Federal Reserve	Two-day meeting starts Tuesday; decision due Wednesday; hold expected	A change in tone can move global markets before the decision
Crude oil	Brent near $115 in two reports and $109.84 in another at 7 AM	High oil raises India's import bill and inflation risk
Foreign investors	One report shows sales of Rs 1,462 crore on Monday; another shows buying of Rs 887.65 crore on Friday	Flows can swing the index late in the day
Results	110 companies report, including L&T, Maruti Suzuki, Bajaj Auto and Tata Steel	Index heavyweights can move the Nifty after results
Rupee	About 95.17 to 95.22 per US dollar	A weak rupee adds to foreign selling pressure

Sources differ on oil and flows. The Kotak Neo and HDFC Sky notes put Brent near $114.7 to $114.8, while a DSIJ note shows $109.84 at 7 AM, and the foreign investor figures belong to different days. For Nifty expiry today, treat these as the general picture of high oil and mixed flows and not as exact levels.

How the Early Nifty Expiry Today Call Has Played Out

Nifty expiry today: checkpoint	Early view	Actual by 10:11 AM
Opening direction	Weak start; GIFT Nifty down about 0.4% to 0.5%	Opened lower; Sensex at 73,281, down 325 points at 9:19 AM
Support at 22,400	Likely to be tested	Not tested; the low so far is above it
Resistance at 22,800	Capped on rallies	Index at 22,787.55, just below
Sector tone	IT weak after global tech moves	Nifty IT down 1.7% at 9:30 AM
Broader market	Cautious	Midcap 100 up 0.29% and Smallcap 100 up 1.34% at the open

So far Nifty expiry today has been more resilient than the early signals. The recovery to near 22,800 puts the index right at the first call resistance on Nifty expiry today, which makes the next hour a test. A move above 22,850 would challenge the call writers, while a slip below 22,700 would test the put support.

Remember that on Nifty expiry today, the Nifty weekly expiry, option premiums can swing wildly in minutes, and a small move in the index can wipe out the value of an option. This article does not suggest any trade.
