AUD_v1 trades AUDUSD using a single boolean entry signal: Williams %R(14) computed on Daily-resampled bars. When Williams crosses up through −50 (close moves to upper half of recent 14-day range) a LONG opens; when it crosses down through −50, a SHORT opens. Each position has a fixed take-profit, stop-loss, 1-week timeout, and Friday-21:00-UTC weekend force-close. No grid, no martingale, no compound-tricks — just a clean single-position bot whose only job is "trade in the direction of the daily-autocorrelation regime."

Strategy spec (live)

• Pair: AUDUSD (Exness Cent #160001992)
• Indicator: Williams %R period 14 on Daily-resampled bars
• Entry: cross at −50, both directions (long on up-cross, short on down-cross)
• Take-profit: 150 pips (was 200 — E46 walk-forward zoom found 150 better)
• Stop-loss: 30 pips
• Timeout: 168 H1 bars (1 week)
• Weekend close: Friday ≥ 21:00 UTC
• Risk per trade: 5% of broker equity (was 10% — reduced after K-fold revealed wider DD bands)
• Magic number: 777401
• Tier choice: Tier C of E52 K-fold ranking — most regime-robust

Backtest performance (22-yr AUDUSD H1)

• Out-of-sample Calmar: 28.34 (vs deployed EMA's 4.3 = 6.6× lift)
• Out-of-sample CAGR: +641% (4-year IS vs 11-year OOS at the 2014-12-31 split)
• Out-of-sample max drawdown: 22.6%
• Out-of-sample profit factor: 4.22
• ~32 trades/year, ~57% win rate (most non-TP closes are also profitable timeouts)
• K-fold across 6 regimes (2004-2026): all profitable, max DD bounded at 24% in every regime
• K-fold Calmar CV: 0.54 (3-4× more regime-stable than aggressive tiers)

Why Williams %R, not EMA?

• Tested 161 indicators across 17 phases (MA crosses, oscillators, channels, trend strength, statistical, Ehlers cycle, regime detectors, fractals, candle patterns, multi-timeframe, adaptive MAs)
• None beat Williams %R Daily on out-of-sample Calmar
• L1 logistic regression and Lasso decode confirmed Williams entries are not filterable ex-ante — the edge is irreducible
• The "edge" is positive autocorrelation in AUDUSD daily returns, likely China/iron-ore commodity-cycle driven (multi-pair test confirmed AUDUSD is structurally 10-30× stronger than EUR/GBP/JPY/CAD/CHF on this pattern)
