"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
"You are much better than lawyers or the phone company because you answer the phone when I call! I just love your customer service." - Comment from Isreal
"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email
"If you want customer service that answers the phone, your best bet is IQFeed. I cannot stop praising them or their technical support. They are always there for you, and they are quick. I have used ****** too but the best value is IQFeed." - Comment from Public Forum
"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post
"Thanks for following up with me. You guys do a great job in tech support." - Comment from Phelps
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip

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.
