"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"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

IQFeed Datafeed Wish List » Please add quotes to historical tick data, now it only provides trades May 13, 2014 12:39 PM (Total replies: 6)

You could cut down on band width requirements using compression. I store all of my tick data using a simple compression system that yields on average around five to one compression. I am sure that other compression systems would give even greater compression. My system allows me to also keep data sets compressed in RAM and decompress them on the fly while I back test. It does require me to store ask, bid and trades in separate files but that should work well for your business as well.

IQFeed Datafeed Wish List » Please add quotes to historical tick data, now it only provides trades May 12, 2014 07:14 PM (Total replies: 6)

I also just signed up for IQFeed and I am disappointed to find that you don't provide all bid ask quotes in the historical tick data. My old vendor provide one week of past bid ask tick data which worked well for me. That would not require a lot of additional storage to provide. It does require about five times the bandwidth over the trade only ticks. I would suggest only making it available when the markets are closed. I need those prices. I may have to go back to my old vendor.
