Dear steve, It happens at times that when ever i download historical data for a bunch of symbols, i get an error message for one or more symbols, the error i get is: !ERROR! !NONE! what does this error signify, does it signify that there is no data available for that particular symbol, or anything else.. And secondly, if i try again after sometimes, i get data for the same symbol!!! why is it so ? This error does not comes every time, but does come at some irregular times.... I use java for connecting to iqfeed... Plzz do help me, in this.... Vishwanath

Unusual problem with historical data Aug 30, 2007 01:35 AM
(Total replies: 1)
Dear steve, I have an unusual problem while downloading historical data. Actually in my program we download historical data for more than one symbols. But what happens is that sometimes, the IQFeed server is not giving any data for one or more symbols. And then immediately if i re-run the program, i get the historical data for that same symbols, for which i was not getting the data earlier. In my program i use 5 simultaneous socket connections to download historical data of 5 different symbols. But at times no data is sent for some symbols. For instance if i run my program and downloaded data for symbol YHOO, and i received also the data. Now if i close the application, re-run it and do the same thing i did earlier, i don't receive any data from YHOO. Why so? Is it because i am opening a lot of socket connection simultaneously for historical data? If so, then whats the max. limit to the no. of socket connections that i can have to download historical data for different symbols ? If thats not the case, the could u plz let me know what is causing it to behave like this? Is it some programming error from my side, or is it some other problem. Plzz do help me in this matter.. Vishwanath...

can we use multiple socket connections for Level I realtime data Jun 27, 2007 05:19 AM
(Total replies: 2)
Dear steve, I had a query regarding using multiple socket connections to IQConnect. We have a requirement of getting realtime data (level 1) for around 100 symbols at the same time. The application is developed in Java. I have a confusion regarding this. Should i use a single Socket connection and give commands for all the 100 symbols, OR should i used different Socket connections at the same time for each symbols. Secondly, we have to use threads to read data from socket, but here also should I use a single thread with a single socket connection for all 100 symbols, OR should i create individual threads (and individual socket connection) for each symbol. Please could u help me in this. How would it affect the performance if we use multiple threads (or socket connections). Eagery awaiting for some good reply... Vishwanath |
