Keltner is one of the few good longterm strategies out there. Specially on EU , and on GU is not bad at all. But people looks for holy grails, for EAs which never fails: if u see an equity curve too straight, or is a martigrid (and it will blown ur account) or is curve fitted, and this is even more dangerius. Every valid startegy has his DD periods: u need confidence and proper money managment: people does not have confidence, because don't know how to correctly evaluate staretgies and so run an EA, it start to lose and they stop it; then the EA recover (but they are out) and they jump in again, but now the EA start again to go in DD. In the menatime they look for a new grail and lose money also on this. It is a neverending story. Learn how to evaluate a startegy, manual or automated, fix your risk and the max DD u want to reach and the max DD which invalidate the startegy.
The recipy to become rich in 1 year does not exist. My opinion is that with forex we cannot become rich, we can only try to boost our overall portfolio performance. Invest in forex only a small part of ur capital and when u put some money on a trading account be ready for the worse. But, never run a startegy because other people do, make ur own research and evaluation. Forex industry is full of craps and BS, but fortunately something good is available
