I am trying to use DSS API function EndOfDayPricingExtractionRequest and PriceHistoryExtractionRequest to collect data
May I know how to get the same result as Eikon desktop using Parameters NULL->PREVIOUS
@Arvinwong
Thank you for reaching out to us.
I don't think that the DSS REST API provides this option.
You can check all avaiable options via REST API Reference Tree.
I am also looking for the solution of same problem. Did you got any valid solution till yet? I couldn't find from your comment section.
