Beginners skip the statistical tests because they look complicated.

Then they blow up their account in month two.

Out-of-sample testing is super basic.

Monte Carlo takes 30 seconds to run.

Walk-forward? Same thing (ok maybe not 30s but still easy if you know how to do it)

These aren't optional.

Beginners who skip validation: 90% failure rate in first 6 months.

Follow a solid process with you want to play this game in the long term.
