Can we have an instrument file with now retired equity symbols so we can pull history data for companies that have ceased to exist? Managing survivorship bias is a core requirement for the history data API to enable robust back testing. It would be great if Zerodha could add this option and explain the need in the documentation so all of us consider this while back testing with the Kite history data.
Kite Connect primarily serves as an execution platform, and while we do our best to provide valuable data, we are not a comprehensive data vendor. For detailed information on unlisted instruments, we recommend reaching out to an exchange-registered data vendor.
