I tried a Tradency demo with my broker. It’s something similar to ZuluTrade, with much more eyecandy, but much less functional, because it’s made in Flash (so you can’t open multiple pages or something else).
The way to choose the signals it’s crazy, the stats are very limited, there is no backtest: you just blindly pick one and hope it’s a winning one.
The demo it’s given with a fixed amount of money: 50000 dollars, an irrealistic amount that won’t produce any decent result. Moreover the demo it’s time limited in 30 days, so it’s impossible to try long term strategies. Also ZuluTrade demos are time limited, but there is a glitch to have them unlimited.
Update: the demo is not limited to 30 days, but is limited until the end of the month. Absolutely useless!
