"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"Thank God for your Data Feed as the only Zippers I see are on my pants (LOL), and no more 200 pip spikes to mess up charts." - Comment from Spiro via Email
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"Can I get another account from you? I am tired of ******* going down so often" - Comment from George
"For anyone considering using DTN.IQ for a data feed, my experience with the quality of data and the tech support has been very positive." - Comment from Public Forum
"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen

I am trying to download the Backadjusted data for the gold, silver and copper instruments but I am not receiving anything, before I used the continuous contracts of these instruments I had no problem, so I wanted to know if I should hire an additional service to obtain this data or know if i'm doing something wrong

These are the instrument symbols I'm using:
gold: QGC#C
silver: QSI#C
copper QHG#C


New IQFeed Forum » Backadjustment of Futures Sep 13, 2022 08:42 PM (Total replies: 1)

We are bringing future real-time data, I understand that you already provides this data with the backadjustment in Futures, but I was wondering if we can apply this adjustment by ourselves knowing the gap and the expiration date of the contract, because we would like to have all the data with this adjustment.

Otherway to have the backadjustment of futures is download all the data, but to do this we have to know the expiration date for each contract and download the data already adjust that day.

If you made this backadjustment of Futures means that you know when to apply it. do you provide any calendar to know when happens this events?

If you have any advise about how we should solve this problem with the backadjustment in Futures, we will be gratefull.
