"Excellent datafeed !!!" - Comment from Arely

"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat

"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark

Author	Topic: NYMEX tick data seems corrupt (6 messages, Page 1 of 1)
rcerda -Interested User- Posts: 9 Joined: Dec 13, 2007	Posted: Dec 13, 2007 08:58 AM Msg. 1 of 6 Hi. I've detected that several symbols (@QHG8, @QGH8, @NQH8, +HOF8, +CLH8, +CLF8, +CLG8, +CLJ8, +RBG8, +RBF8, +RBH8, + HOG8) are getting wrong tick data when requesting Historical Ticks via COM (timestamps are not in cronological order as expected and I'm not sure if the price is ok either) The problem began yesterday at 7:00 pm New York time and seems to hold up to now. I chated with DTN Support about 2 hours ago and they told me that this is an exchange problem at the NYMEX/GLOBEX that was detected yesterday at 6:00 pm by DTN staff. Whats the most efficient way to get notifications regarding this type of problems? Is this the correct Forum for that type of issues? Do you have an estimate of when this will be solved? It's been more than 12 hours since it began... Thanks.

We were noting many issues with the data last night, but it has been corrected as of this morning. If you have anything in question, please send it thorugh as an attachment or email us at support@iqfeed.net. Kind regards, Sarah DTN Trading Markets

We concentrated on the primary contracts and didn't get the Combined Session symbols fixed unfortunately. Jay Froscheiser DTN - Trading Markets

Yes, I've just doubled checked the +CLF8 symbol using the sample VC++ application that comes with the IQFeed DEveloper Client and it still shows bad data for yesterday (12-Dec-2007). Tick data jumps from 10:00 am to 7:00 pm, with nothing in between, although it looks like the missing data is later on the feed. The other symbols mentioned on my previous post show similar issues.

The purpose of my post was to say we didn't get all the data fixed, especially the combined session symbols. Thus, you will see this issue until we are able to get it corrected on the server.

You also mentioned that 'primary contracts' were fixed first. Does that mean the electronic (Globex) only contracts? Can you tell me how to identify those, i.e. is there a rule for figuring out which prefix should I use (+, @ or none) to get those? Thanks.
