Quote: skunk is correct, historical open interest for futures is available in IQFeed v4.1.0.0, which is currently in BETA. That info is in the release notes, and will be updated in the online documentation when the release goes LIVE. Thanks!

Quote: Can anyone comment on how long it takes to turn a history request intraday?

If I call the history server, I am getting ET's of up to 8 seconds for 10 days of minute bars on ES(eMini S&P)...

I have been poking around on my code to speed things up but nothing seems to improve the turnaround time...

If I request the last 10 days of minute data (in single minutes)...it takes up to 8 seconds to report back the entire block, at which point I launch the next request in the que...

Somthing must be wrong...

It should not take 8 seconds to get 10 days worth of 1 minute bar data.

I buffer the incramental callbacks until i see an ENDMSG then kick it to the que cruncher and the entire block is sent as a text chunk...to the listners..
