Currency Trading

Hi all,
Having tested different automated systems, popular as forex eas, my opinion is that the more complicated a trading system is, the more the results suffer. So I searched for such a forex expert advisor that would use a very very basic strategy.
After many tries I came upon B.O.R.N Night owl - a
forex system forex expert advisor, which seems not to utilize any sophisticated indies etc but simply use the geographic gap between New York and Tokyo - that means that after NY closes, there is no other large financial institution open until Tokyo opens. Well, Australia seems to be in the gap, but the volumes traded there are not significant.
The logic is that when there are no succicient volumes, the currency ranges are easily predictable, but you should really read the original presentation of the authors - this is really strange that they reveal the whole details of the strategy their robot is using unlike the other vendors on the market.
The about page is what you are looking for which contains the strategy details.
Can you please comment on this, guys - I wuld really love to hear a second a different opinion, thanks!
