Update February 2010: It has come to my attention that USDBot is a scam. It is a clone of a free EA called Opto123. The developers of USDBot released version2 which has completely different logic and based on simple martingale that will blow your account. Be careful!
USDBOT is a new over hyped EA released by Mark Trenton. The marketing is copied from fapturbo, even the iframes with the accounts. However the results shown on page are from few weeks of trading and they are not updated in real time.
I decided to dig deeper and analyze the robot USDBOT. It trades EURUSD and USDJPY on D1 timeframe. The short term backtest for 2009 looks good:

However USDBOT seems to be optimized for the 2009 only:

Same picture on USDJPY. Good results in 2009 but bad in 2005-2008:

The bottom line is USDBOt is optimized for the current market conditions and it is hard to predict how it will perform in future. We have placed in on the demo account for the forward test.
