offline paper trading

Hello,

Can anyone recommend to me any decent paper trading software that can save historical data and let me trade off-line, similar to OANDA FXGame??

Thanks in adavance

So: over the weekend iv been looking into importing historical data to Ninja Trader but i keep on getting error messages and im sure i have the format right in the text file - creating an instrument say called $eurusd - and naming the text file the same $eurusd but keep on getting error messages. Its really annoying not having the internet at home but i would really like to do some paper trading at home so can one shed any light either on tips for importing historical data into ninja trader or another program which is best to use offline...........

Regards,
