I always like to hear about really cool gadgets and addon's that have function, ingenuity or overall coolness. Most trading software has something wierd that is amazing.
I use TradersStudio and like the "walk forward feature of TradersStudio on a portfiolo". Am quoting Gyles words from his review of TradersStudio as follows:
I use PT MultiStatation, there are a lot of useful features... but if you want weird one - i've just known that PT MultiStation can read RSS))) you can read any RSS feed you like right in the terminal. http://profstation.com/online_trading_broker/rss
