Quote from marketsurfer:
Great article, Rodney. Thanks for making me aware of it. Is Eckhardt saying trend following doesn't work here?
"â¦Trend-following doesnât work only because of the tail risk but tail risk turns up the volume.

FM: We spoke to Richard Dennis a couple of years ago and he said that trend-following is getting more difficult and systems donât hold their edge as long. Do you agree?
BE: In general I agree that it is getting harder and you have to improve, though I donât know that you have to improve faster. Hastiness can be costly in this game. When you are doing your research and you are improving, it should be with the confidence that the system you are currently trading is good. The value of the current system you are trading gives you the time to make a deliberate and cautious improvement. "
Also the section on curve fitting seems to be very applicable to amateur system sellers.....
