Hello I am moving from windows to linux; I would like to know if there are some real time data systems on linux? thanks a lot in advance pascal
If you are looking for a wide data feed in the low-to-mid $1000's-ish pricing, NxCore is a nice system that runs great under Wine, which is a Windows API emulator. Other Windows data feeds also may run under Wine, or at the least VMWare. There are some higher-priced full feeds, such as Activ and QuantHouse, that run natively on Linux.
Chances are you can also find data providers who can give you real-time data via FIX. The QuickFix and QuickFix/J libraries can be used on Linux to interface with anyone providing FIX connectivity.
314, I like QuickFix, but does anyone disseminate quotes via regular FIX (which is pretty inefficient for large volumes of data)? Or are you speaking of FAST FIX? I think Spryware will disseminate quotes via FAST FIX, but as far as I know that's the only one, and I think that's quite an expensive/high-end solution as my understanding is that they sell just software, and you need to buy the data, separately, from the source(s).
If you are looking for something a little less expensive, I can report that DTN IQFeed runs on Linux using wine. I've only had it running for a few days, but it has been flawless during that time. OS is Ubuntu 9.04 64 bit. 32 bit IQFeed.
You're right--I don't know of anyone who disseminates quotes in bulk via FIX; I guess I must have not read quantparis's question very closely, or it was really late.
Pretty easy Not for stocks, but futures and forex. * Open account with someone allowing you access via Rithmic'c API * Use Rithmic's API - they also provide market data. RIthmic is developing on Linux so comes out there, first
