Hey @Omkar Nandode9, TradingView is the charting library. The data is handled seperately by us. We source data from NSE in realtime and what you see on the chart are the prices we have received from the exchange. We receive thousands of data packets every second and this is then distributed to all logged in users instantly. Sometimes, there may be discrepancies because the data packets aren't sent uniformly by the exchange. For more information, read this post34.
We correct any mismatches by the end of the day if and when they do occur.
