What about the "XLF" example where fields 18 and 66 where both empty? that wasn't an option that was an ETF.

Wanted to know if anyone else is having issues with the format of the feed field values? For the last week or so I've been having issues with time stamp field 18 being empty also fields 4, 11 and 12 and other fields as well.

how to insert large amounts of data Feb 25, 2011 04:05 PM
(Total replies: 1)
Hi, I'm building a multithreaded app that's using the producer consumer queue threading logic...I'm pushing the feed data into a queue which a worker thread processes (inserts and updates database tables). The problem is towards the end of the trading session the volume becomes VERY heavy and the queue builds at a faster rate than the worker thread can process causing latency with the inserts by 2 or 3 mins! Does anyone have any solutions or suggestions on how to flush the entire queue into the table vs. individual inserts or some other way to resolve this? By the way, I'm using MySQL 5.5 with .net connector (API) and C# 4.0 Thanks, D.Allen Edited by d_allen on Feb 25, 2011 at 04:06 PM

Feed bottleneck Feb 11, 2011 05:12 PM
(Total replies: 0)
I'm using two different activeX controls - one to receive stock data and the other to receive options data. I wanted to know if this is the correct way to go about receiving data for different asset classes. If so I'm running into a performance issue! I'm backing up the data from both assets types to my database and I have a client app that accesses the database. As the day progresses iqFeed performance gets worse and worse; consuming 25-40% of my system resources and the lagging by as much as 15 mins! What am I doing wrong here? Thanks! -DA Edited by d_allen on Feb 11, 2011 at 05:14 PM Edited by d_allen on Feb 11, 2011 at 05:15 PM Edited by d_allen on Feb 11, 2011 at 05:18 PM

How do I put the QuoteMessage on another thread... Jan 30, 2011 04:41 PM

hey Helg37 sorry if I came off like I was trying to critique your code, lol! I just don't understand what's going on and what I'm suppose to be doing :) I need to understand what's going on and "WHY". That way I'll know how to modify it to fit my own needs and also I'll be more knowledgeable about what's going on and what I'm doing. That's why I had so many questions. I'm thankful that you replied and provided me with a solution, I'm just not clear on what's going on and how I'm suppose to use the example that you provided. So please don't take my questions the wrong way, I'm just trying to learn and not just have you guys hold my hand and give me the answers...it's VERY important for me to understand what I'm doing. :) allen Edited by d_allen on Jan 30, 2011 at 04:47 PM Edited by d_allen on Jan 30, 2011 at 04:49 PM Edited by d_allen on Jan 30, 2011 at 04:49 PM

hey helg37, what is the "Prints" data type that's used in the generic container (concurrentQueue)? is that the quote argument dataType from iqFEED? also are GetPrint() and WorkerPrint() in the iqFEED quote event? and where is the worker_print thread started? i assuming it not started in the iqFEED quote event? also I don't understand why youre locking the conconcurrentQueue object? doesn't the EventWaitHandle object synchronize your thread?

How do I put the QuoteMessage on another thread... Jan 26, 2011 05:56 PM
(Total replies: 8)
I'm a novice C# developer and I'm using the activeX control which fires the axIQFeedY_QuoteMessage event. I have a couple of method calls which parses the feed then inserts the results into a database but this seems to overwhelm the windows form and consumes too much of my system resources so I wanted to put the axIQFeedY_QutoeMessage event on another thread. I tried to create a thread pass the event to an anonymous delegate: ThreadStart myThreadStart = delegate() {axIQFeedY_QuoteMessage(object o, AxIQFEEDLib._DIQFeedYEvents_QuoteMessageEvent e);} Thread myThread = new Thread(myThreadStart); myThread.Start(); I don't know where or what object to pass to the axIQFeedY_QuoteMessage or how to instantiate the axIQFeedY_QuoteMessage. Can someone please explain/show me what I'm doing wrong and the correct way to go about this. Thanks! -Allen Edited by d_allen on Jan 26, 2011 at 05:57 PM

Using feed with database Jan 10, 2011 03:47 PM
(Total replies: 2)
Hi, I'm an entry level developer and with very little experience with DTN...I wanted to know if anyone had has any sample code that they can provide me with showing how you're using the feed in conjunction with a database. I'm current "trying" to parse the feed and insert the the results in a MySQL database and I'm also querying the database and displaying the results on the front-end via a C# client app that I'm working on but I'm having a lot of trouble with performance, consistency, etc... Basically I'd just like to look over some code with interaction between the a front-end, DNT and a database. Thanks,

I remember browsering of a thread where some guys where asking for sample C# apps. Does DTN currently have newer sample apps other than the ones that are currently provided? If so how do I go about getting them? Edited by d_allen on Jan 6, 2011 at 02:43 PM

Thanks Steve. Hey, how and where do I get a current Listed Market List? Will I have to write a routine and display results via a control? Or can I simply download your IQ Feed Client wich possibly provides the Listed Market Lookup? Edited by d_allen on Jan 6, 2011 at 11:51 AM
