"I "bracket trade" all major news releases and I have not found one lag or glitch with DTN.IQ feed. I am very comfortable with their feed under all typical news conditions (Fed releases, employment numbers, etc)." - Comment from Public Forum
"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
"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

I am currently using IQFeed protocol 6.1. There use to be historical tick data from December 21, 2021 and older. But now, this historical tick data is no longer available. I am requesting HTT,AAPL,20211221 000000,20211222 000000,,,,1,, and I receive an IQFeed NO_DATA response. This is not just for AAPL, but for all symbols for data before December 21, 2021. Selecting a date in mid November yields the same result.

Could you please confirm this error behavior on your end?

During regular US trading hours (9:30-16:30 US Eastern time), only 8 days of ticks data is available. Outside trading hours you can receive up to 180 days of data.

I can confirm Yair is exactly correct.

You are limited to 8 calendar days of tick data between 9:30am - 4:30pm Eastern Time. Outside of those hours you can access 180 calendar days.
