Author	Topic: New Historical Message (HDX) Option Open Interest (7 messages, Page 1 of 1)
EspressoE -Interested User- Posts: 30 Joined: Mar 8, 2006	Posted: Feb 23, 2009 12:47 AM Msg. 1 of 7 The Open Interest field in HDX seems to always be zero. When is this going to be available? For example, the following request should show open Request: HDX,MQF BO,5 Results: 2009-02-20 23:44:22,2.10,1.68,1.68,1.97,308,0, 2009-02-19 23:44:22,2.22,1.94,2.22,1.94,176,0, 2009-02-18 23:44:22,2.36,2.09,2.12,2.09,225,0, 2009-02-17 23:44:22,2.36,2.04,2.04,2.14,298,0, 2009-02-13 23:44:22,3.20,3.10,3.20,3.19,52234,0, !ENDMSG!, Should be: 2009-02-20 23:44:22,2.10,1.68,1.68,1.97,308,495, 2009-02-19 23:44:22,2.22,1.94,2.22,1.94,176,415, 2009-02-18 23:44:22,2.36,2.09,2.12,2.09,225,369, 2009-02-17 23:44:22,2.36,2.04,2.04,2.14,298,215, 2009-02-13 23:44:22,3.20,3.10,3.20,3.19,52234,2332, !ENDMSG!, Thanks, Eric

EspressoE -Interested User- Posts: 30 Joined: Mar 8, 2006	Posted: Mar 20, 2009 10:04 PM Msg. 4 of 7 Hi Steve, Did the server team get back to you on when they might be able to get Option Open Interest in the historical messages? Just out of curiosity, how do you receive the Open Interest? Does that come from the exchange directly on a tick-by-tick basis, or is it computed at the end of the day? Is it possible to reconstruct the open interest from the previous open-interest value and the tick data?

Unfortuantely I do not have an ETA at this time for how long it would take to implement. As far as calculating open interest from the feed, we do not calculate this (it is provided to us from the exchange). Since we do not have information about the parties involved in the trades, I do not believe it would be possible to calculate this on a tick by tick basis from the feed.
