although I risk of being banned from this forum immediately, I would like to request feedback from this community about a new project of mine.
I am the maintainer of ActiveQuant.org - the oldest open source trading development framework still under development (yeah! 10 years this year). Our site gets regular hits from EliteTrader - I see it in the referrer.
As many users complained rightfully about the lack of documentation around ActiveQuant, I have kicked off another project that aims to bring interested developers smoothly into automated trading.
It is very much alpha, but we ship already a user interface into which people are able to plug in their trading system and run it. As we are now also on working out an introducing broker partnership with some well-known brokers, we are able to include live quotes in a demo account, so that programmers and developers can use their trading system on a paper account with live quotes. At the moment only FX.
The entire thing is very programmer oriented and less plain-user at the moment, but eventually this is going to change in the future.
