24,000 cracked, reclaimed, Re-Floored. Now Sensex expiry

That is not a nervous bounce. That is a session that found a buyer at 23,800 and never looked back. 04%. It reclaimed almost everything it gave back on Tuesday. 30 of the Nifty 50 stocks closed in green. IT led the rebound, the same sector that got routed on Tuesday's Korea chip rout was the one that pulled us back. But, and this is the whole game, who did the buying? Because it was not the FIIs. So here are the official numbers. On Wednesday, the FIIs sold almost 1,843 crores while DIIs bought 3,637 crores.

So the rebound that reclaimed 24,000 was a domestic rescue. The locals bought the dip the FIIs were handing them. That is the second day in a row that DIIs have carried the market on its way back. And the FIIs didn't just sell cash. Look at the futures, guys. The FII net short in index futures went from 2,28,561 contracts on Tuesday to 2,29,053 on Wednesday. They added to the short, into a 1% rally. They deepened the hedge, and that is where we are not looking in.

That is the stock futures: they have built a huge stock position underlying that hedge. That is the desk that is not convinced. That is the desk that is protecting its long stock book and refusing to chase it. Now hold that thought, because the next number is the one that changed my mind about that bounce. 78. Call-heavy. That is extremely bearish. The biggest open interest sat on the call side at 24,000, the broken support had become a resistance of overhead supply. That's what I built Tuesday's call on.

21. It had flipped completely. 21 crore contracts of open interest sitting there as the support. And the build-up tells you it happened in one day: put writers added 44 lakh contracts at 23,900, another 29 lakh contracts, and stacked deep tail puts down to 22,500 and 22,000 as well. So max pain pulled right back to the 24,000 strike, that was the expectation, where the market should close back, and where the magnet, the pinning, should happen. And here is the lesson, and write this one down.

When a level breaks and then gets reclaimed, the price chart will tell you the what. But the option writers tell you whether it's real or not. A put writer is someone selling insurance. They only sell a 24,000 put if they are willing to buy the index at 24,000. 21 in a single session, and the open interest piles up under the reclaim level, that is not retail noise. That is the smart money voting that the floor, the support, is real. A reclaim that the writers refuse to fund is a trap.

A reclaim that the writers rebuild under, that's the support. Wednesday, they built it. So the pros agree as well, by the way. In the participant data, the pro segment flipped from net short on Tuesday to a net long of 8,500 contracts in index futures on Wednesday. The clients are still long. The DIIs are long. Only the FIIs are still short, and that's the tension that walks us into today. So now let's get back to today's expiry. Sensex weekly expiry. And the GIFT Nifty is pointing to a gap-up of around 24,100, plus 83 points, which means Sensex opens this morning somewhere near 77,200 to 77,300.

And that is the problem, because that opens us straight into the resistance. Here are the Sensex levels for expiry today. Overhead, the call writers are stacked at 77,000, then 77,500, then a heavy resistance at 78,000. That 77,000 to 77,500 band is the immediate battle, and a gap-up open lands us right inside it. It is 0DTE. Underneath, the put support sits at 76,500 and then 76,000. Then the real floor is much below. Max pain is sitting around that 76,700 to 76,500 mark.

So read the geometry. We are gapping up into a call wall, a resistance, on a day those calls are going to expire. India VIX has cooled back towards 13 from Tuesday's 14 levels. So the volatility is bleeding out. And that matters, because on a 0DTE, falling volatility plus a price pinned near the writers' strikes means theta and gamma do the work, not the direction. The one-standard-deviation expected move on Sensex today is about 520 points, call it 76,470 to 77,510. That is the range I am playing for today.

That's a tight box. The expiry wants to pin, not trend. Remember that, guys. The gamma confirms it. With heavy open interest stacked both above at 77,000 and below at 76,500, the dealers are long gamma inside that range, which means every push gets sold back towards the middle. The amplified, runaway move only comes if we break clean above 77,500 or clean below that 76,500 mark. Inside that box, expect a choppy session today and a pinning happening towards that 77,000 range. Outside it, expect speed and a rally once again.

One more layer, guys, because today is a two-day event. After our market closes, and tomorrow we have a holiday, so tomorrow the markets are closed, the United States releases its Core PCE, the Fed's favorite inflation number, plus durable goods and the final first-quarter GDP. A hot PCE keeps the hawkish Fed exactly where it is. And you have seen what that has already done: gold has cracked below the 4,010 mark to a 7-month low, silver fell almost 5%, crude dropped over 4% to around $70, even Bitcoin is at a 2-week low.

A strong dollar is vacuuming money out of everything at once. For us, that crude crack is a silver lining, because $70 oil is a gift to an importer like India. It eases the import bill and the inflation math. 86, below that 95 mark, on dollar strength. So the setup is a friendly crude tailwind, a hostile dollar headwind, and a US inflation print tonight that nobody wants to be caught naked in front of. So here's how I am reading the day. Above 77,000 and holding, the reclaim extends, momentum towards that 77,300 and 77,500 mark, and that's where the call writers will defend.

Losing 76,500, the gap-up was a relief rally, and we fade back towards that 76,000 mark. Inside 76,500 to 76,700 and upwards towards 77,000 is an expiry pin, so expect the expiry to happen towards that 77,000 mark. And on a zero-day expiry, you respect the pin. You do not carry a naked position into falling volatility with a US inflation print waiting on the other side. So the floor that cracked on Tuesday got reclaimed on Wednesday, and the writers rebuilt it underneath again.

Today the question is simple: does the gap-up confirm the reclaim, or does it run out of room at the resistance? Watch 77,000, the whole day lives there. That's the tape behind the chart.
