What is the best trading strategy for beginners?

The best first strategy is one you fully understand, trades rarely, and has an obvious benchmark — not the one with the best backtest. The 200-day moving average regime filter is the classic candidate: own the index ETF when price is above its 200-day average, hold cash when below. One number, a handful of trades a year, decades of research behind it, and every decision is explainable. Run it against buy-and-hold on the same page and you'll immediately learn the real lessons: trend filters lag at turns, whipsaws cost money, and drawdown reduction — not return enhancement — is what they actually buy you. Graduate to faster strategies after you've watched one slow one behave for a while.
