Using the Eikon .NET API, it is dead simple to retrieve summarized historic bars for a given view (e.g. LAST_PRC_1, BID, ASK) (returned as DateTime / Open / High / Low / Close / Volume) for a specified interday or intraday period.
Using EDP, I understand that you have to build the bars yourself by joining the values from the correct open / high / low / close / volume fields?
To do this, one has to know *which* fields to retrieve and to join.
For example for an equity like ADSGn.DE it would be OPEN_PRC, HIGH_1, LOW_1, TRDPRC_1, ACVOL_UNS, and for a currency like EUR= this would be OPEN_BID, BID_HIGH_1, BID_LOW_1, BID, NUM_BIDS.
There are myriads of security types and combinations. In the EDP API, is there (or is there planned) a way to retrieve meta information for related fields for this purpose?
Currently, we don't have metadata in Historical Pricing API. However, I have contacted the development team to verify if there is any plan to provide metadata in the historical pricing API.
I will keep you updated.
