junkone -Interested User- Posts: 28 Joined: Jul 18, 2007	Posted: Mar 18, 2009 08:27 PM Msg. 1 of 6 i seem to find issues with the last bar from dtniq daily. i use the intraday bars and set my intraday settings to show day session only. so it starts at 9.30 and ends at 16:00 hours every day the last bar seems to spike. for eg worden dtniq goog finance RIMM 40.98 41.12 40.98 BWLD 36.47 35.6 36.47 i am guessing that bad ticks are making it in. but at a daily basis, this is getting annoying as my indicators get messed up with bad data as it reflects inaccurate closing prices.

The prices you mention for IQ are actually at 16:03-16:04. The last ticks at 16:00 for both RIMM and BWLD do match what you quote for Worden and Google. What software are you using to access the data? It appears to me that it isn't actually cutting off the data at 16:00 like you are requesting. Jay Froscheiser DTN - Trading Markets

In the quote editor I do have afterhours data. Kinda surprised at that with the settings and all. Maybe TJ can help. j
