Quote from cornix:
Many people underestimate the effect knowing MFE/MAE may have on their trading.
Must say that thanks to a few people I got to know during past 6 months my beliefs changed about objective trading towards believing it can be much more objective than I ever thought and still have a nicely looking equity curve without those insane draw-downs mechanical systems usually have.
I'm not sure where this notion that mechanical systems usually have insane drawdowns.
Here's an analogy: Not every robot is created equal.
Since machine learned systems aren't designed by humans, the machine learning is what makes the drawdown so high. When the machine is built as a base model, then the machine learning isn't whether a machine learned designing programing built its functions and parameters, but that the machine learning portion of the program should come from intelligent design and not from the machine building itself.
There's a misconception that genetic algorithms write their own code, and, it's true, some do, but they aren't effective and certainly not as effective as a base model that gets re-optimized genetically by checking its parameters and not simply by redesinging its own codes and maybe a few parameters. They're both machine learning, but one is so much more effective it's not fair to clump mechanical systems together like that. There are machine learned algorithms, genetic algorithms, and the parametrization procedures for the two are so drammatically different that this does show a lack of experience in distinguishing the application of these two technologies.
Really the two have different purposes.
It's funny that this is the topic. I finished optimizing a parameter in my codes that is designed to analyze portfolio movements, and not simply targets of trades (particularly this has not been discussed on this board). When I do that, I went from a $37k profit and $15k drawdown, to $10k drawdown for $57k.
So was that beneficial? I shouldn't do it because people say that's not the way to do it? Well it is. When people tell you not to do it that way they don't know what they're talking about because they probably don't have algorithms capable of the consistency most seek in their trading. It comes from a smart robot, not a smart robotic self-constructor.
