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

I've been using the same software for several years to download historical data. Today is the first time I've seen the above error message. Can anyone explain exactly what this error means and what is wrong with my requests?

Here are some specific requests that get this error:

HIT,EHSI,60,20180701 092900,20180731 155900,,092900,155900,1
HIT,EHPTP,60,20181001 092900,20181031 155900,,092900,155900,1
HIT,EGYH,60,20181101 092900,20181131 155900,,092900,155900,1

Even Friday, this software worked fine, I only began getting these errors on Saturday 2/9. Does anyone have a suggestion as to what is wrong?

Hello, are you still having problems with this? For me, those request do not return data but they are also not returning the error you are seeing.

I am also seeing these errors on-and-off. It seems that if I enter a valid trading start date then it resumes working and gets out of the loop that constantly throws the "Invalid interval reference time" error. For example:

Original request - error:
=> 20190317 21:34:49.028 (Lookup) HIT,@KCK19,60,20190315 000001,20190317 235959,1,,,1,H-@KCK19,,s
<= 20190317 21:34:49.427 (Lookup) H-@KCK19,E,Invalid interval reference time.

Modified request - good data:
=> 20190317 21:34:57.536 (Lookup) HIT,@KCK19,60,20190312 000001,20190317 235959,1,,,1,H-@KCK19,,s
<= 20190317 21:34:57.942 (Lookup) H-@KCK19,2019-03-15 13:30:00,97.65,97.50,97.65,97.60,13763,56,0

Original request again - good data:
=> 20190317 21:35:02.040 (Lookup) HIT,@KCK19,60,20190315 000001,20190317 235959,1,,,1,H-@KCK19,,s
<= 20190317 21:35:02.443 (Lookup) H-@KCK19,2019-03-15 13:30:00,97.65,97.50,97.65,97.60,13763,56,0

I am sorry for the delay in responding. The issues you were seeing should be resolved. There was a server in our rotation that we had to take offline.

Feel free to contact us at if you continue to have issues.
