Using .net example 2.0.0 (HistoricalPricing.GetSummaries) and connecting via deployed TREP I get the following error:
"Endpoint requires an ISession that supports data requests."
I think this is because I have to specify the corect service name, like I do for streaming subscriptions.
But I cannot find a method similar to ".WithService()" that is used when getting data via Pricing.CreateStreamingPrices.
At present the Historical Pricing data cannot be accessed via a TREP session. I believe that this is something which will be offered in a future version of TREP.
At present, you would have to use a Desktop or RDP session i.e. connecting to a local Eikon or to the Cloud.
For an RDP session, you would need an RDP account - feel free to contact your Refinitiv representative for further details.
