Forex Backtesting strategies of famous trading gurus...

Hi,
I know that trading is a hard business and this is why I like it. To say that "Trading" is easy is just a lie. In the whole finance industry there are a lot of people who are just lying. They are making a lot of money by offering seminars and writing books about strategies that don't work.

But now I'm here to backtest some of them (Background: economist & data scientist). I will post the results on this forum when I'm done.
My problem right now is, that I would like to know which strategy I should backtest first...

Any suggestions?

Best,
Alan.K
