Indeed FC, counter trend system on Dax. I did not actually trade this system, it was something somebody who had recently got to grips with TS posted to me and that I decided to watch. It worked a bit better on FTSE but still down vs. Aug peak. It seems they fell into the usual system trader trap when one gets first access to the evil temptation of the optimise button even though they swore it was not over optimised.
I posted to show how easy it is to go horribly wrong. Expect a lot of commercial systems may perform like this.

And perhaps the perils of thinking that the most recent data is the most important.
5 years minimum imho, including bull, bear, flat, wild and boring periods.
By the time you understand the latest sentiment, it's usually over.
