Donchian Breakout for US500 (S&P 500)

Buy the highest high of the last N bars — the original turtle-trader strategy.

Why Donchian Breakout Works on US500

Donchian breakouts buy when price closes above the N-bar high. It captures regime changes — the moment a market wakes up from a range. Fails in chop (every false breakout is a small loss) but the long tail of trending wins more than compensates. Most profitable on volatile assets like XAUUSD and crypto.

The S&P 500 (US500) is the global benchmark equity index. Strong long-term uptrend with regime shifts; momentum and trend bots dominate, mean-reversion works in QE periods only.

Equity indices reflect aggregate corporate earnings, sentiment, and Fed policy. They trend more cleanly than individual stocks and gap less than commodities.
