I would like to query historical futures for a given underlying (HSI or KOSPI200 for example)?
I can use /Search/FuturesAndOptionsSearch, which allows an `UnderlyingRic` to search for current futures, but I can't find any documentation for an equivalent option in HistoricalSearch or HistoricalCriteriaSearch.
Yes, you are correct. There is no UnderlyingRic option in HistoricalSearch and HistoricalCriterialSearch. Therefore, those endpoints don't support UnderlyingRic.
