This is a follow up to the closed discussion above.
It was mentioned: "Equilibrium price is shown in the open value of the ohlc quote in the tick during pre-market"
I have been checking the above through websocket streaming, but found that at least on some days the equilibrium price is not getting updated. The price changes at 9 when the pre-market opens, but there are no changes after that. Is this an error? Asking this as NSE shows the price changing continuously between 9 am and 9:07 am (please find the screenshot below).
