IQ Feed provides different amounts of history depending on the type of database you select. If you select tick or time database under 1 minute, it only knows about a weeks history of data, as all are based on ticks. If you select a 1 minute or longer database, you get over a years worth of history. EOD data is much longer history.
You can find out the details by going to the IQ Feed website. When you choose a database, AB can aggregate any database to a longer timeframe, but it can not make more history than is there. I am finding 1 minute is the best compromise for me for time bars, though I have to go to 5 seconds if I want to have volume bars or range bars.
