Hi, the English-version of my web is http://www.tradeproject.de/Start.23.0.html?&L=1. You can also click at the little US-flag in the upper right corner. As soon as you are on the English site you will also see the English version of the screenshots. The videos will be changed in the future â they are old anyway. If you download the software from the English site you will also get the English version of TradeProject. So I hope it is not necessary to use google translation.
How about http://www.trading-shim.org/ ? Open-source and C++, but maybe not very easy to make it work with a Microsoft OS.
Stuff I have been working on for a while: https://github.com/rburkholder/trade-frame Uses IQFeed as a primary data source, and uses Interactive Brokers for executions. Originated in Windows, now primarily used on Linux. It can track portfolios, positions, orders, and executions. Has some options calculations. Live charts can be maintained. A basic simulation engine is available.
