I was using Quotes apis and noticed that it does not return data for certain symbols. More specifically these NSE:JSWHL, NSE:DBREALTY, NSE:RPOWER, NSE:TTML
These symbols are list with "-BE" suffix in Kite Web interface. For e.g. "JSWHL-BE" for NSE exchange.
These scrips fall under the BE category. To fetch them, please append 'BE' to the scrip name. You may also refer to the instrument file for the latest list of scrips.
