ATR Breakout SHORT
Short when an ATR spike signals a downside volatility expansion. The one conditional survivor of the 2026-06-28 fresh out-of-sample re-test — a genuine altcoin-short timing edge — but a fine-grained walk-forward shows −321% / 62% MDD in 2024-H1, so it is unsuitable for unsupervised real-money trading. 2,839 trades, PF 1.42.

Overview
ATR Breakout SHORT fires when the Average True Range (14-period) spikes above its moving average threshold — signalling a volatility expansion — and price is moving downward. Unlike BB Squeeze which waits for compression first, this strategy catches the early momentum of a directional volatility burst.
Status: SHELVED (stand-down). This is the one conditional survivor of the 2026-06-28 fresh out-of-sample re-test: a genuine altcoin-short timing edge that beat brainless shorting across regimes and held up against costs and tail risk (36/40 coins). But a fine-grained walk-forward — finer than annual windows — exposed a structural −321% / 62% max drawdown in 2024-H1. An annual window hid that losing sub-regime. So it is not an all-weather edge and is unsuitable for unsupervised real-money trading: only consider it with a bull-market stand-down filter and a small position size. We mark it shelved, not verified, for exactly this reason.
How It Works
- ATR spike — 14-period ATR crosses above 1.5× its 20-period moving average
- Directional filter — price below its 20-period MA confirms downward bias
- Volume confirmation — volume ≥ 1.5× 20-period average
- Entry — SHORT on bar close
- Exit — TP 10% / SL 3% / 48-bar (2-day) timeout
- Risk — asymmetric: 1:3.3 R:R (3% risk, 10% reward)
Why It Works (Thesis)
ATR spikes in crypto typically mean one of two things: a genuine directional move, or a wick-spike that reverts. On a 1H timeframe with the 3% SL, you get stopped out quickly when it’s a wick. When it’s a real downward expansion — an altcoin breaks support, a leverage cascade starts — the 10% TP captures the bulk of the move.
The SHORT edge (not LONG) appears structural: in crypto, downward volatility expansions tend to be sharper and less frequently faded by new buyers in the first 2 hours. Upward expansions attract FOMO buyers that compress the follow-through. Unlike the other sweep presets, this one survived the 2026-06-28 adversarial kill — but only conditionally, because it bleeds badly in bull sub-regimes (see the 2024-H1 drawdown above).
Results (2-year backtest, IS/OOS split, measured 2026-05-04)
| Metric | IS (May24–May25) | OOS (May25–May26) | Combined |
|---|---|---|---|
| Total trades | 1,513 | 1,326 | 2,839 |
| Win rate | ~38% | ~34% | 35.9% |
| Profit factor | 1.57 | 1.28 | 1.42 |
| Coins profitable | 48/50 | 36/50 | — |
Low win rate is by design — the 1:3.3 R:R means each win covers 3+ losses. The combined PF (1.42) is reproducible, but read the caveats: a finer walk-forward shows it is regime-dependent, not all-weather.
Caveats
- Conditional survivor, not deployable (2026-06-28). Finer-than-annual walk-forward exposed −321% / 62% MDD in 2024-H1. The strategy is real altcoin-short alpha in bear/choppy regimes but bleeds heavily in bull runs — unsuitable for unsupervised real-money trading. Shelved pending a bull-market stand-down filter; use small size only.
- OOS PF (1.28) is lower than IS (1.57) — some IS outperformance did not carry forward.
- Tight 3% SL generates frequent stop-outs. Requires accepting a ~64% loss rate.
- Not live-tracked. Backtest only.
- All LONG configurations remain unprofitable on OOS data.
