About Price Sources

Price data is maintained by source and date in Eagle. This requires each unique source of price data to be setup in Eagle in order that it be recognized and processed by the RDC engine. Sources typically represent external market data vendors, or internal systems that feed data to Eagle. The two main types of Sources used in RDC Prices are Vendor Sources and Gold Copy Sources.

Vendor Sources predominantly contain vendor-supplied data, from sources such as Bloomberg and IDC.
Gold Copy Sources contain Best of Breed prices.

Data Strategies request Vendor Source prices based upon the established Source Rules. The received prices are then loaded into the Eagle data warehouse, where the Data Strategy Validation Rules perform predefined tests on the prices, then select the single best price for each security. That best price is the pushed to the Gold Copy Source. The Gold Copy Source is used to calculate the market value for each security position held by each entity using that Gold Copy Source.

When a Source is setup in the system, it is assigned a source interface instance. The source codes are stored with the prices in the SECURITY database, using the assigned source interface instance. This allows for multiple versions of prices for the same security to coexist for reference during processing on a given production date.

Sources must be assigned a feed type for which they will provide data, so they are available in the creation of Source Rules. In RDC Prices, the Vendor Sources are assigned a Feed Type of Vendor Price (PH) and the Gold Copy Sources are assigned a Feed Type of Best Data Engine (BDE).
