I can't see the financial industry getting behind FOSS, but there's very much a missed opportunity for Data API companies. Let trading firms pay standard rates to get access to high-resolution, realtime data; the secret sauce in each firm then becomes what kind of trading algorithm you write to make the most profit off that data. Ensuring that everyone has potential access to the same underlying data helps dissuade claims that profits are made from insider trading. There should be all kinds of data for all kinds of domains available when you fork over a little money for an API key.
