I feel a little of bitter arguments here as anything related to 'Pure pip producer'. He's a controversial man, personally I like his funny style, but I don't like so much when any post distorts any time he's mentioned.
Any investor should focus on maximum return and minimum Drawdawn, right? Some of the comments here suggest that should be a bad advice. Well, if our goal is to win money I can't think on any better advice.
Problem is that Darwins with short time and/or small number of trades are statistically insignificant to make any conclusion. I wouldn't trust them unless the trader behind could expose similar Darwins with statistical significance and success (even so I'd choose his other Darwins).
Another problem is that ANY strategy with linear growth more sooner than later will crush because it's overoptimized, martingalled, doesn't use stoploss and various other reasons that I don't care too much. Eventually they crush no matter what. That's one of the very few certainties of this business, these systems vanish with time and I've seen that usually the trader behind come back again with a renewed holy grial. Hundreds of examples on MQL, no need to put names surely the most veterans traders could think on several examples.
It can take a month, it can take a year but they crush for sure. Golden rule. If you are a gambling investor Ok; you can win a lot of money. If you look for consistency and long time survival it's a death wrong path. Not an opinion, it's a fucking fact.
Some equitys are really appealing but any of these perfect equities pass neither the basic filters neither survive more than 1-2 years on the best of luck.
On this sense I reckon that D-Score makes a good job to prevent a naive investor.
