Hi, we are tracking the BNF OI data to calculate PCR, on 16-09-2024, the OI data has been wrong, when calculating PCR, Zerodha OI is giving as 0.57 and in NSE official option chain is giving as 1.2. Also, the previous day zerodha is giving pcr as 1.4. how come in one day the PCR got reduced from 1.4 to 0.57.
