COI: For each of the 25 strike levels (ATM ±12), Call/Put COI = current OI − previous OI from the live option-chain feed. COI PCR = |Put COI| ÷ |Call COI|, so PCR is always positive. Total OI is not used for this PCR. VWAP: Price and VWAP now both use the same traded instrument — current-month NIFTY futures. VWAP is the futures exchange average traded price (ATP); no spot-basis adjustment is used.
