"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
"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"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

How many days in the past can I download history data in the HIT format?

8 days during market hours, 180 days outside of market hours. However, if the interval is divisible by 60, i.e. minute data, there is no limit.

Does this also applies to HTT data? I haven't been able to get any data older than a few days, both during and off market hours.

Here is an example query that is returning "Invalid symbol."

I'll give it a go after the markets close, it will certainly be invalid currently due to the data being older than the system can currently see.

For the historical data system, is market close at 4pm EST? Or does it not allow access to the data until after-hours trading ends?

The time frame where history is limited is currently set for 9:30 to 4:30 EST

I tried this and it appears to be working, but let me know if you see something different.
