instrument_type for INDEX changed few months back?

mb12
mb12 edited July 9 in General
Initially, if i recollect well, the indices had the instrument_type of 'IN', where as now it's instrument_type has been changed to 'EQ' which is same as that of equity, and segment = INDICES. For other instruments, the instrument_type uniquely identifies the type of instrument e.g. CE, PE, FUT, EQ, but for indices one has to check 2 fields together i.e. instrument_type & segment. Isn't this change in instrument_type for Indices inconsistent with other types of instruments (where only instrument_type could uniquely identify type) & wouldn't it be simpler if the instrument_type itself could identify the Index type? Such a change also makes filtering or checking for instrument type complex as now a custom check needs to be added just for index type (that also checks for segment value)!

    AFAIK going back to a few years, for indices the instrument type was always 'EQ' and segment was 'INDICES'.
    And if I wanted to parse the instrument list for indices I always used the filter segment='INDICES'.
    So there has been no recent change.

    Just checked this on all instrumentlists since about 2020 for 'NIFTY BANK'. Thats last 5 years

    the indices had the instrument_type of 'IN', where as now it's instrument_type has been changed to 'EQ' which is same as that of equity, and segment = INDICES.
    Yes, as @MAG highlighted. There has been no change in the instrument list fields including INDICES. INDICES always has the exchange name it belong, and segment as `INDICES`.
