Real-Time Market Mechanics for Indian Traders
By Shakti Tiwari | optiontradingwithai.in
Introduction
Most NIFTY traders trade blind. They look at price, maybe a moving average, and hope. But the real money is in order flow — where the big players are actually placing bets before the move happens.
This article shows you how to read OI, PCR, and volume like a pro trader.
What is Open Interest (OI)?
OI = number of open contracts that have not been settled. It represents money parked by smart money.
Key rule: Rising OI + rising price = trend continuing. Rising OI + falling price = trend weakening.
PCR (Put-Call Ratio)
PCR = Total PUT OI / Total CALL OI
- PCR > 1.2 = oversold, bounce likely
- PCR < 0.8 = overbought, correction likely
- PCR 0.8-1.2 = neutral zone
Volume Profile
Volume at price shows where institutions transacted. High volume nodes = support/resistance.
Live Example (NIFTY 22,500 zone)
- CE 22500 OI: 2.1M
- PE 22500 OI: 3.4M
- PCR: 1.62 → bullish bias
- Max pain: 22,400 → mild downside risk
- Recommendation: Buy 22500 CE on dips with SL 22,350
Conclusion
Order flow beats indicators. Track OI, PCR, and volume daily.
