Hi! I am getting no data for the NSE-EQ of the following stocks: LUPIN, NTPC, JUSTDIAL, NHPC, BEML. I guess that their token values are wrong. But these are the tokens that I downloaded from your site. So kindly check if there is any problem at your end.
@SAURABH Are you referring to the WebSocket API? I just verified, these instruments are ticking (you can check on kite.zerodha.com. It uses the same instrument_tokens)
