Author	Topic: How far back for minute & Second data for stocks (5 messages, Page 1 of 1)
cunparis -Interested User- Posts: 29 Joined: Jan 1, 2009	Posted: Mar 14, 2009 05:23 AM Msg. 1 of 5 I'm curious how far back minute & second data goes for stocks? Minute data for ES goes back to around oct 2005, but what about second data?
cunparis -Interested User- Posts: 29 Joined: Jan 1, 2009	Posted: Mar 14, 2009 09:48 AM Msg. 2 of 5 For example i find that some stocks don't have minute data. AXB is an example. Is there a reason why it wouldn't have minute data?
DTN_Jay_Froscheiser -VP, Product Operations- Posts: 1746 Joined: May 3, 2004 DTN IQFeed/DTN.IQ/DTN NxCore	Posted: Mar 14, 2009 09:56 AM Msg. 3 of 5 Im not sure why you wouldn't be getting minute data on AXB. I just pulled minute data and it goes back to October 1 2008. Are you unable to retrieve minute data on other symbols as well? In general, this is what we are storing: 30 calendar days of tick (includes pre-post market) and several years of 1-Minute history (Forex back to Feb 2005, Eminis back to Sept. 2005, Stock/Futures/Indexes back to May 2007) retrieval for charting and time & sales data . We don't currently store second data intervals. The 30 days of tick data is only available during non regular market hours. During regular market hours, the tick data is limited to 8 calendar days.

If it only goes back to oct 2008 that would explain it. But why is there only data from oct 2008 if you stock several years of 1 minute history? Thanks for the info on the tick/second intervals. I'll take that into account. One final question, when recovering minute data, I find that it's fast from 2009 but if I go back to early 2008 it's very very slow. Is this a known limitation?
