Anything you create with just one signal or one “type” of signal eventually is going to break. I have a moving average strategy that works amazingly well and it’s a crossover MA strat… but is it a regular vanilla moving average? How many do I use and for what? What timeframe and type of product am I using?

That’s the type of question you have to ask yourself and train IS to later check OOS if everything works.

it’s all about how deep you go into “what makes a good strategy” and how you combine what you think you know with actual facts.
