@preshan.govinder,

if data is not available in the GUI, it will not be available via the API.

I did a test for DSS time series data, from 1990 till today, did not receive any data at all:

No usage to report -- 1 Instrument in the input list had no reported data.

In Eikon I see it only has data for very few fields, related to closing or last prices. I therefore tried a time series request for all the different close price fields ("Close Price", "Alternate Close Price", "Official Close Price", "Universal Close Price"), none have data.

I therefore tried a TRTH request for raw market price data, and that works; it delivers data for fields like HST_CLOSE, GEN_VAL2, etc.

Here is a request in Postman that delivers data (I filtered the FIDs to keep only the most interesting ones):

This might be a solution for you, if you have TRTH.

@preshan.govinder

I did a quick test and it seems that only Tick History Raw extraction has the data.

This could be a server side issue. I would suggest open a support ticket.

Here is the Tick History Raw extraction example.
