It's possible to get current pricing source for a security (PRICING_SOURCE field). Is there any field that returns the list of all available pricing sources for defined security?
Thank you.
No - it's not currently possible.
Any fields (i.e. visible in FLDS in the terminal) are accessible via the API - such as the PRICING_SOURCE field in the question.
However, there is currently no functionality like the terminal commands PCS or ALLQ in the API at the moment. There is a request for this functionality with the Bloomberg programmers, and you can contact the Bbg helpdesk to have yourself added to the request to be informed when it becomes available.
