Anyone using eSignal Market Data API?
- Thread starter mcdull
- Start date
esignal api is pretty good as long as you're trading small subsets of the market (eg <100 symbols)
bigger than that you can see performance problems affecting all of esignal (not just the api feed). this can be true even in more recent threaded versions of esignal
1. good
2. not with their desktop api product. if you are an esignal partner they can make their protocol feed available
3. good with small numbers of symbols
most tradelink users trading hundreds or thousands of symbols will use something like iqfeed or nanex. otherwise esignal is very good.

Quote from tradelink:
iqfeed is tcp-based so it will work on linux
Well, everything is tcp based (except online games using udp), so that is platform irrelevant. To the best of my knowledge they do not allow direct connection to their servers, you have to use their client which resides on your box, and that client is windowz based. I have found some requests on their forum dated back in early 2000's from people asking them if they are going to provide linux client and the response was that they do not see much interest.
If this is not correct, I would be personally interested, because it is a good feed...

"iqfeed api is tcp-based" iow
meaning you speak raw tcp to get at their feed. (rather than some brokers which make this difficult, don't provide information/etc)
you're correct that their client runs on windows (exe). this client proxies the feed for you, you speak to client via tcp. no special iqfeed or windows libraries required to talk to client.
so you should be able to run client on another machine or a local windows VM, and just receive feed on linux.
alternatively, you could use iqfeed in tradelink and talk to tradelink on linux using tcp.

Well again, with all due respect.
"iqfeed is tcp-based" is correct, but irrelevant for the situation we are talking about.
"so it will work on linux" is not correct, we agree
"no special iqfeed or windows libraries required" is irrelevant because you need winz operating system to run iqfeed client, and iqfeed client IS library compiled to run only on winz OS
Of course you can run all those things ( I don't know what the tradelink is, but it doesn't seem to help, just another hoop to jump through), but why would I do that when other native solutions are available? iqfeed would have to be the only solution (and it's not) to start improvising, but then I might as well run the freakin' winz.
mcdull was looking for linux solution.
Enough said, cheers

If by linux solution one means running trading systems or code on a linux box that processes data from iqfeed, see our above posts. Windows running in a vm or seperate machine would also be necessary, but your code and systems would run on linux.
If by linux solution one means no windows anywhere, you could look at td ameritrade's http api.
