Live PCR from NSE option chain. Auto-refreshes every 3 minutes. Check this before every trade session.
Important caveat: PCR is a sentiment gauge, not a trade signal. Use it as context — a PCR above 1.3 tells you fear is elevated, not that the market will definitely go up. Combine PCR with max pain level, top OI strikes, and India VIX for a complete picture before your trade. Practice your PCR-based strategy with real option chain data on PaperPe.
