"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 Developer Wish List » Nasdaq Total View Sep 10, 2006 06:59 PM (Total replies: 7)

I know it has been mentioned in at least one previous topic, but has there been any further consideration by DTN_IQ to provide Nasdaq Total View. I know it will depend on how easy/difficult it would be to implement into the API, and the resulting "mark up" on the data fee.

I understand that Total View has gained a lot in popularity over basic level 2. I would be willing to pay more for this service.

IQFeed Developer Support » COM vs SOCKET?? Mar 12, 2005 05:45 PM (Total replies: 0)

I am in the planning stages of a small application. I haven't noticed any discussions or info in regards to contrasting & comparing COM and SOCKET for receiving level 2 data from IQFeed servers.

In what instances is one preferred over the other?

I will be reading level 2 data from multiple symbols, using VB. Naturally, speed and stability are very important.
