TurtleUltimate is a rewrite of the Turtle strategy by DeepSeek V4 Pro (reasoning model). Given the 25-line original, DeepSeek identified three core defects — no regime filter, no ATR stop, no risk-based position sizing — and produced a 100-line version that fixes all three. In our 1-year BTC backtest, Ultimate moves from -1.62% (original) to +1.86%, cuts drawdown by 33%, and halves fees by filtering whipsaw entries.
