DTN.IQ Client Software Support » Migration to V4 from V2.3.0.1 Nov 11, 2005 10:58 AM (Total replies: 1)

Hi,

I was using IQ Feed developer 2.3.0.1 for a while (since June 2004).
I just installed IQFeed Developer v 4.0.0.2 few days ago and it looks like that I am now receiving much less transactions per symbol that I used to be through streaming quote data.
As an example on November 1st with version 2.3.0.1 I received 5962 Update Messages with different last price for Symbol CSCO from NASDAQ while the total volume of the day was 43379125. If I compared with the data I received for November 10th with v 4.0.0.2, I found strange that I only got 3834 Update Messages with different last price for Symbol CSCO from NASDAQ while the total volume of the day was 110208123. Globally it seems that I receive from 2 to 4 times less Update Message with the newer version.

Thanks
