2.3.0.3 Timing issue for watch list Jun 8, 2005 02:02 PM
(Total replies: 4)
This issue has been resolved via a change in Ensign to watch all symbols using one request instead of making multiple requests with 1 symbol per request. Thanks for the feedback. Sincerely, Howard Arrington www.ensignsoftware.com

2.3.0.3 Timing issue for watch list Jun 6, 2005 04:16 PM
(Total replies: 4)
Testing with 2.3.0.3 and using the watch command in a loop to ask for 40+ symbols to be watched. Upon initial request for 40 symbols, the Connection Manager Feed Stats form will show 6 symbols. If I repeat the request the number of symbols followed will go to 11, repeat full list again, number of symbols followed will go to 16, then to 21, etc. This I can verify by seeing which Fundamental records are returned. My conclusion is that I am making requests to the watch list faster than the IQfeed Connect can process the requests, or is there a handshake I should be using so I do not overrun the request process. I interface directly with the DLL using Delphi 6. The TCP/IP socket is using this type of an example string: tcp5009.sendln('wIBM'+#13+#10+#0+#1,#1) I have a 1/50th of a second delay after the string is sent to the socket, as that seemed to be an effective delay pace for the 2.3.0.1 version. How should I be sending the watch list so all symbols are reliably processed and begin to update? Thanks. Sincerely, Howard Arrington www.ensignsoftware.com |
