"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry
"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
"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"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
"The people at Nirvana have very nice things to say about your company and I can see why! Price and service is a potent combination." - Comment from Ed
"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"If you want customer service that answers the phone, your best bet is IQFeed. I cannot stop praising them or their technical support. They are always there for you, and they are quick. I have used ****** too but the best value is IQFeed." - Comment from Public Forum
"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.
"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
"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email

IQFeed API Questions » How to get equity options historical data? Mar 29, 2024 05:53 PM (Total replies: 0)

Hello everyone,

Taking the QQQ option expiring on April 29th as an example, with a strike price of 444, if I want to obtain the bid/ask prices and volume for the Call/Put of this contract for every 5 minutes between March 25th and March 30th, what should I do? I tried using the HIT command with the symbol QQQ2419D444, but the result came back as "Unauthorized user ID". I asked technical support, and they told me I don't need to subscribe to real-time options data to access historical data, which has left me quite confused.
