"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum
"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 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

IQFeed Developer Support » Getting only 8 days of tick data after hours Apr 7, 2016 10:56 PM (Total replies: 0)

I'm completely new to this, so I hope I'm not asking a question with an obvious answer. I wasn't able to find anything in the documentation or using the search feature.

The first thing I wanted was to write the historical tick data for @ES# to disk for reference and back-testing. I simply edited the HistorySocket example program to write the data to file. It works fine unless I request more than 8 days of historical data. I'm not getting any errors or anything, it just runs for 20 minutes or so, gets 8 days of data and then !EndMessage! for the end of the signal.

I'm aware that 8 days is the limit during market hours, but it is almost midnight in NYC right now so this shouldn't be an issue. Is it timing out? Do I have to request data in 8 day chunks? I'd appreciate any help, thanks.
