Miscellaneous Messages » Support for Linux API for the datafeed? Jan 7, 2009 06:20 AM (Total replies: 33)

It worked like charm :-)
I was quite surprised, because I don't have that much experience in linux, java and using sockets. But I managed to sort things out in couple of hours. And IQFeed (both versions 4.4 and 4.5) is working perfectly under Wine.

It's the last issue I had to fix before shifting to Linux, so bye-bye Windows XP :-)

Miscellaneous Messages » Support for Linux API for the datafeed? Jan 6, 2009 01:33 AM (Total replies: 33)

Finally I started my move to linux environment, so I'd also like to have a linux version of IQFeed software.

Meanwhile, could somebody share experience in using IQFeed via wine?
I'm thinking about this solution:
IQFeed -> Some data interface in wine -> my program. However I'm not sure about the data interface part. Does anybody have some experience in this?

IQFeed Datafeed Wish List » TimeStampMessage after RegisterClientApp and more about the feedback Jun 23, 2008 12:25 PM (Total replies: 2)

Thanks. "Not Found" message works fine.

It would be really nice to have an option to request TimeStamp from IQFeedY or to receive it automatically after connecting to the server..
If you do not want to create a separate command, just send the timestamp message together with Echo message, for example.

IQFeed Datafeed Wish List » TimeStampMessage after RegisterClientApp and more about the feedback Jun 23, 2008 04:04 AM (Total replies: 2)

I want to synchronize my program with the IQ server time. The problem is that the program has to wait up to 1 minute until next TimeStampMessage comes..
It would be really great if IQ could send one (or even a sequence of 3-5 for better accuracy) TimeStampMessage immediately after connection.



Another annoying thing. If the user sends WatchSymbol with wrong symbol name, nothing happens - no error message, no other feedback (or it is not documented?). Even the WatchSymbol return true..
So I do not have any way to find out if the request was successful or not. Yeah, I know there is a symbol lookup, but I do not want to do 100 lookups for every symbol entered..

The solution is simple: if the symbol given to WatchSymbol is wrong it should return false. If that is not possible, then API should send the System message, like "Error: symbol not valid".

In general I'd really like to get much more feedback from the API. If I do something right, give me a "good boy!" message, if I do something wrong, give me an error message. Silence is the worst. That makes programming and testing really difficult.
