I did some more testing to my system, including 2011. It wasn't a very good year for trend following. It turns out maximum drawdown was -62%. Only three times in history (40 years) drawdown was bigger:
- 1980 / 07 -74%, profit next year +280%
- 1992 / 06 -64%, profit next year +71%
- 2005 / 08 -74%, profit next year +119%
It seems like it's a good idea to stick with the system.
