We are using the DSS REST API and the `PriceHistoryExtractionRequest` to retrieve end of day data. We are running the request on the date, at 6 p.m. NY time, that equals the `QueryEndDate` in the request body for a list of RICs provided in the `InstrumentIdentifiers` field. In general, the majority of RICs in the list return a value for the `QueryEndDate`. However, there are RICs that do not populate values until later and so we only get values for these if we run the report again later that day or even the next day.
Is there a way to find out, in a systematic way, what time a given RIC will be available via the `PriceHistoryExtractionRequest`?
