Why has the turtle trend-following system stop working?

You can't selectively choose a few securities and say something still works. ANything can work when one selectively choose the success cases.

Agreed. You have to know ahead of time something is going to trend. Of course, if something trended for a long time thus far, there's a decent shot of that trend continuing for a while (given other contextual information).

Trend following still works. Just got to know what to trade, your scan criteria and risk management.
