1. What are the different software available for live trading? I know about http://www.sierrachart.com but it doesn't support Linux and I don't like the idea to be dependant of their server.

2. I'm actually learning C++ and I'm thinking about creating a command line trading software. Maybe PHP could be more efficient since I could make a webpage on my VPS? I don't mind learning any language.

3. I feel a bit lost with the JSON format. Anyone have open source example I could look at?

I don't mind buying an affordable software that I could directly setup to use JSON format.


Thank's for help!

EDIT: Found this software list but nothing seem to be a complete solution with Linux support: https://en.bitcoin.it/wiki/Software#PC_apps
