Live
The live desk opens with Stage 2
During market hours this page will carry the 1-minute chart for NIFTY and BANKNIFTY and the live option-chain board — open interest and its change by strike, fresh longs and shorts, put-call ratios on OI and volume, max pain, the heaviest strikes, ATM implied volatility, the futures basis — updated as the exchange updates, on the paid desk.
Until then the desk is end-of-day: everything on it is built overnight from the exchange's published files and is complete by 08:30 IST.
