ETH Multi-Regime Asymmetric Continuation — Robust Multi-Window Edge

Verdict: robust · Asset/TF: ETHUSDT 1h · Sample: 4 Walk-Forward Windows

Hypothesis

Single-regime momentum strategies on Ethereum often suffer from severe drawdowns during range-bound chop, while pure mean-reversion suffers catastrophic losses in persistent trending runs.

By bifurcating entry logic into two asymmetric regimes:

1. High Volatility Persistence Momentum: Long entry when volatility persistence is strongly positive (vol_regime_persistence_24 > 0.32) without weekend shock distortion (weekend_vol_shock <= 0).
2. Deep Pullback Mean Reversion: Long entry on extreme negative volatility persistence (vol_regime_persistence_24 < -0.18).

Coupled with an asymmetric 2.14:1 reward-to-risk ratio (3.0% Take-Profit vs 1.4% Stop-Loss) and a dead-zone decay exit, this structure extracts continuation yield while tightly capping consolidation drawdown.

Backtest & Walk-Forward Performance

Robustness & Falsification Proof

• Fee Resilience: The strategy passes strict falsification criteria under 4.4 bps taker fees (+1.06% net, Sharpe 1.11 across 136 trades), demonstrating that the edge stems from structural market asymmetry rather than maker fee rebates.
• Asymmetric Payoff: Wide 2:1 TP/SL ratio (3.0% TP vs 1.4% SL) provides statistical downside protection against volatile wick stopouts.
• Out-of-Sample Consistency: Returns remained positive across all 4 walk-forward test periods.
