Index price feed for NSE indices across brokers has frozen due to an unknown reason. NSE has closed F&O market at 11:40 am and the cash market at 11:43 am. NSE says that the update for the re-opening will be shared later."Trading is halted on NSE across brokers. We are waiting for it to come back online. For equity orders, you can use BSE," Zerodha said in a tweet. Retail traders who frequent the price feed took to Twitter register the technical error."There is an issue with live ticks for NSE indices (Nifty 50, Nifty Bank and others) across brokers. We are in touch with NSE to have this fixed," Brokerage firm Zerodha said in a tweet.There is an issue with live ticks for NSE indices (Nifty 50, Nifty Bank and others) across brokers.
