Noticed today there was a new client software as of 7/6 on the site.
I've had some problems in the past w/ backfilling speed as well as AmiBroker problems (both of which I"ve posted). Do you know if this new update solves any of these issues? Can you share how this new version is different? Thanks |

The backfill speed was increased in the latest version, but it isn't very noticable on most of the 3rd party clients. It is greatly increased for our own DTN.IQ client, which was using an older method for receiving historical data. In essence, we upgrade our DTN.IQ client to use the same interface that 3rd party apps use with IQFeed (so you can imaging how slow it was before!) In our testing, we see a slight increase in speed when pulling a large amount of tick or minute data. However, on small or medium sized requests (30 days or so), you won't see much difference.
There are a couple things within our history protocol which could be improved to increase the speed of retrieval. We are aware of it, and hope to get the protocol changed in the future. It isn't a quick change unfortunately and we have some other more pressing items we are working on getting released before we tackle it. As for other general problems with Amibroker (or any other 3rd party software), there aren't any issues directly related to the IQFeed client that we are aware of. Any stability problems were addressed in previous releases, so as long as the 3rd party software utilizes the latest versions, it should be extremely reliable and stable. I run IQFeed 24/7 on a machine with 3 3rd paryt apps connected to it. The only time I stop or restart it is for MS security updates. During its operation, I start and stop various 3rd party apps (including DDE into Excel) throughout the day (never stopping IQFeed) and never have issues. If you can provide us some more details on any stability issues you are seeing with AmiBroker, we will do our best to work with them to address it. Jay Froscheiser DTN - Trading Markets |

Re: AmiBroker.
We ran some tests internally to see if the new client improves download speed within AmiBroker. Here is our results: Using 2 machines setup as follows: Machine 1 - 1.6 Ghz with IQFeed 4.1.2.0 Machine 2 - 2.0 Ghz with IQFeed 4.1.0.0 Pulling 120 days of 1 minute data on INDU Machine 1 took 7 seconds to pull the data. Machine 2 took 15 seconds to pull the data. Thus, the new version of IQFeed appears to be about 2x faster. We also tested both versions of IQFeed on the same machine (not sure of the specs on this machine). Using 4.1.0.0 it took 30 seconds to pull the data (not sure why it took so long). Then installed 4.1.2.0 and it took 6 seconds to pull the data. Using a different software package (Qcollector), we found that the download times between the 2 versions of IQFeed were nearly identicle, coming in at about 5 seconds.

Silly question, but where is the new client software update? I searched both the Download and Support pages, and only found the link to the client software v2.4.6.0, dated Feb 23:
http://www.dtniq.com/template.cfm?navgroup=supportlist&urlcode=33&view=1 Perhaps you update the web site with this informatin, unless I was silly enough to have missed seeing it! I'm using Amibroker, do I have to update anything on their side? Many thanks, Paul |

That is the current version of DTN.IQ. We have a new version that will be released shortly. However, if you are looking for the latest version of IQFeed(v 4.1.2.0) you can download it from www.iqfeed.net.

Thanks for the quick reply, Jay. I'm sorry I didn't specify, but I would like to know the ETA of the next IQFeed client (later than 4.1.2.0). There's a NYMEX miNY backfill problem in 4.1.2.0 that I'm really itching to leave behind.
Thanks! |

If (let me know if I am mistaken) you are talking about the backfill data being multiplied by 100, this is a server related issue and the new server code should be released this weekend that will correct it. Please let me know if there is another issue you are referring to.
