"I am keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email
"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott
"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton
"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum
"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

Data and Content Support » FUBO day OHLC not loading Dec 24, 2020 02:38 PM (Total replies: 1)

For US Equity Ticker "FUBO":

Historical intraday OHLC loads normally, but the daily OHLC is immediately returning an error (E,Connection Timeout Error.).


This appears to be fixed now, thanks much.


I apologize, the correct ticker for IQ is BHW1019R50. But this is a system-wide issue, just about every option I check is incorrect, the open interest for today is identical to yesterday.


As an example, the IYR June 50 Put (BHW100619P00050000) had open interest of 25449 yesterday. This morning, the update message still had the value 25449. However, the correct value as of this morning according to both Bloomberg and Interactive Brokers is 35643. This has always been correct prior to today.


The Update message for options does not have the updated open interest today. When is this problem going to be fixed?

Can an IQFeed rep please comment on this?

Now that the IQ32.dll is no longer required, how long before Linux is supported?


Any status on this issue? Did the test fail for you?


Ok, I have reproduced this bug using the DTN example. Then I upgraded to the newest version, 4.6.1.0, and tried again. And the bug still exists. I ran this program on both my Vista and XP machines, and in both cases I get the same error.

For the first 10k loops, no problem, the correct data is always returned:

100,2009-09-17 16:33:51,28.4900,684,3918982,28.2500,28.4200,3632467,0,0,E,

But sometime between 10,600 and 10,800 loops, this error is being returned:

100,E,Could not connect to History socket.

It happens *EVERY* time without fail. The only solution is to reboot the machine.

Here is the class. It is an exact replica of the LookupClient.java class distributed with IQFeed, with the addition of a simple while loop.


public class LoopingTestSentToDTN extends IQ_32 {

int a, b;
BufferedReader in, sin;
BufferedWriter sout;

public void IQConnectStatus(int a, int b) {
this.a = a;
this.b = b;
System.out.println("IQConnectStatus("+a+","+b+")");
}

void dayticks() throws Exception {
String symbol,days,maxDataPoints,beginFilterTime,endFilterTime,direction,dataPointsPerSend;
symbol = "A";
days = "1";
maxDataPoints = "1";
beginFilterTime = "";
endFilterTime = "";
direction = "0";
dataPointsPerSend = "100";
sout.write("HTD"+","+symbol+","+days+","+maxDataPoints+","+beginFilterTime+","+endFilterTime+","+direction+","+dataPointsPerSend+";");
sout.flush();
String line = sin.readLine();
while (line!=null && line.indexOf("!ENDMSG!",0)==-1) {
System.out.println(line);
if (line.equals("!SYNTAX_ERROR!"))
line = null;
else
line = sin.readLine();
}
}

void run() {
RegisterClientApp("IQFEED_DEMO", "1.0", "0.11111111");
try {
if (a!=0 || b!=0) return;
Socket s = new Socket(InetAddress.getByName("localhost"), 9100);
sin = new BufferedReader(new InputStreamReader(s.getInputStream()));
sout = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
in = new BufferedReader(new InputStreamReader(System.in));

int i = 0;
while (i < 20000) {
dayticks();
if ((++i % 50) == 0) {
System.out.println("####### Count: " + i);
}
}
} catch (Exception e) {
e.printStackTrace();
}
RemoveClientApp();
}

public static void main(String args[]) throws Exception {
LoopingTestSentToDTN me = new LoopingTestSentToDTN();
me.run();
}



The problem is that something in DTN's implementation is leaking. I thought it was my JNA bridge to the DLL that was leaking, but I recently implemented the DTN java solution and it still fails.

It is very easy to recreate. Try to load HDX data over TCP/IP for 11,000 symbols. When it gets to 10,800 symbols, it will start returning "Could not connect to History socket".

I am not leaking socket references or anything of that nature I assure you. If DTN were to setup a simple, continuous load from a PC, they would find the same exact problem.

The only solution I have found is to reboot the entire PC. That is a real pain, as you can imagine.
