I am having issues requesting historical data. I have already have socket a connection to get tick data and that works fine. I created a second socket to request historical data, however I have tried various formats to get historical tick data to no avail. I have tried
HT,GROW,2;
HT,[GROW],[2];
[HT,GROW,2];

I have also tried by getting the second socket to initialize the feed and tcp/ip before requesting historical data and tried the three combinations however no luck.

Interesting that the error messages are not consisted for the same format.

I have attached a screenshot of the IQFeed log. The left side (green background) is from the first scenario and the right side (yellowish background) is the second scenario.

Anything I am doing wrong or is there something not mentioned in the manuals that I need to do.

The second socket is connecting to the lookup port 9100.

The history server requests need to be in calendar days (not trading days). This means that requesting 2 days on monday morning (before market open) for most contracts will not return any results (since you are requesting monday and sunday's data).

Thanks. Did not realize it was calender days. One more question though. DTN website states on e can get historical tick data for 8 calender days. However I am only getting data for 6 days.

I requested tick data for GROW specifying 10 days and the I only got data from 2007-09-19 08:07:00 to 2007-09-24 am. Which is 6 days.

This is a side effect from the new server code that was rolled out this weekend. There are some hardware limitations that are preventing us from servicing the entire 8 days currently. Our server team is currently working on a software solution to this issue.

Thanks
