Author	Topic: ID in symbol lookup? (5 messages, Page 1 of 1)
adrian -Interested User- Posts: 28 Joined: Oct 24, 2008	Posted: Oct 28, 2008 12:28 PM Msg. 1 of 5 I'm confused by the symbol lookup functions SSE, SSF, SES, etc. I don't see any way to pass a request Id and the returned lines don't contain anything to indicate that they are from a symbol request. How is this supposed to work in a real application where we may have several active concurrent requests for streaming data or have multiple threads performing different requests? Can you please add a request Id?

At this time, only history requests in the new request protocol (beta) have this functionality. In future versions of IQFeed we will be enhancing the other interfaces. The intended method for using IQFeed lookups without a requestID is to simply make sure your previous request has completed before making a new request OR to make the requests on seperate connections to the LookupPort. Also keep in mind that we maintain a complete list of symbols that is updated once a day available for download on the website here: http://www.dtniq.com/product/mktsymbols.zip

If you are asking if there is a complete list of ONLY equities, the answer is no. You would need to filter out the equities from the above list.
