"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

Recently, I am getting error to login at the first attempt, but subsequent attempt will succeed. Do you know what could cause this error? I haven't seen this before. Also, is there a way to kill iqconnect process and restart it again if the call back routine timed out in curtain time?

I would like to add stock charting to my trading program. I am not a GUI person, does anyone know what are the good stock charting libraries out there? If I want to learn how to develop a stock chart, what are the things I need to know. My primary developing language is C#, but I code server side Java for a living.

Data and Content Support » DTN unable to provide realtime data? Aug 21, 2007 11:06 AM (Total replies: 10)

Hi dhakme, Who is the other data provider? Do you have good experience with it?

Hi Steve,

Could you please help to figure out the workaround for the broken real time feed from 148 servers? I found out three types of errors:
1) not found returned.
2) real time feed arrived late
3) returns corrupted messages like
F,NDY XG,C,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,n,,,,,,,,,,,,,,,,
P,NDY XG,C,,,,,,,,,,,,,,,,,,,,,,,n,,,,,07/31/2007,,,,,,,,,,,,,,,,12,2,,,,,,,,1,,,,,,,

I can easily work around 1 & 2. But I am having difficulties to figure out workaround for 3. It seems IQFeed got stuck somewhere, once it happened, the symbol will not be updated. The only way I found out is to disconnect & reconnect to IQFeed. Since 148 servers return the corrupted messages quite often, the reconnection to IQFeed is fairly frequent. Somehow, this process causes IQFeed Client to crash.

Could you please help so that I can get the data feed behind & go back focusing on trading?


Since Option Search returns expired contracts, I tried OptionChain lookup. I found two problems:
1) It doesn't return LEAPs, I sent in "OEA,HD,1,4;", no LEAPs returned.
2) It returns invalid option symbols, with LookupClient,

Q to quit
Symbol: GOOG
Leap (1/0): 1

try GOO AA for instance, again, with streamer

IQFeed Developer Support » Can't find SOX.X from 148 servers Aug 2, 2007 12:04 AM (Total replies: 1)

This is output from LookupClient, it can't find SOX.X

Q to quit
Search text: SOX.X

but it is on DTN website§ion=guide&web=iqfeed&start=101&maxrows=50&symbol=SOX&searchtype=symbol&exchange=&alpha=1

if that's the case, what happens when new series are issued?

Hi Steve,

I am still seeing this? do you know if I need to wait till Aug to not receive July series?

Steve, I need to clarify my earlier post about no updates from 148 new servers occasionally. I do get intermittent updates, except it is a corrupted message. I attached part of logs from 148 servers.
