The Setup: False Breakdown Below 52000
BankNifty spent the first hour grinding lower toward 52,000. Every retail trader on Twitter was calling for 51,500. But the options data told a different story entirely.
52,000 PE had massive OI buildup, nearly 15 lakh contracts. When price dipped below 52,000 briefly, it triggered a wave of fresh short selling from retail. That was the trap.
Reading the Squeeze
The telltale signs were all there:
- 52,000 CE OI dropped sharply (unwinding, not fresh selling)
- 51,800 PE saw aggressive writing (smart money betting on bounce)
- Delta on ATM options flipped in minutes
By 12:30 PM, BankNifty had ripped 400 points to 52,400. The trapped shorts scrambled to cover, adding fuel to the rally.
Expiry day traps like this happen almost every week. The key is watching WHERE the OI is heaviest and WHO is adding positions. Retail follows price. Smart money follows OI. Be on the right side.
