name	donchian-strong-regime
description	Use when writing a trend-breakdown short gated by a triple-confirmed strong-bear regime — donchian short, structural breakdown, regime-gated trend follower, EMA-separation plus ADX plus N-bar return confirmation. Validated on BTC; fires only in confirmed bear regimes and takes zero trades in chop by design. Pairs with bollinger-reverter-4h.

Donchian Strong-Regime Short

Trend-breakdown short, gated by a triple-confirmed strong-bear regime. Stays out of chop entirely. Validated on BTC/USDC:USDC over 162 days (2025-11-20 → 2026-05-01).

Searchable under: trend follower, breakdown, regime-gated, donchian short, structural break.

Backtest evidence

Window	Trades	Win rate	Profit	Max DD
Full period (162d)	6	100%	+6.69%	0%
First-half / strong bear (82d)	6	100%	+6.69%	0%
Second-half / chop (80d)	0	—	0%	0%

The triple-confirmation gate produced zero trades in the rangy second half — exactly the behavior a regime gate should produce. Every fired trade in the first half captured the trailing stop for profit.

Thesis

In a confirmed strong-bear regime (ema separation, ADX, recent momentum all aligned), a close below the 24-bar low (4 days of structure) reliably continues lower. The gate prevents the strategy from firing during sideways/rangy markets where the same signal mean-reverts.

Mechanics

• Pair: validated on BTC/USDC:USDC; expected to behave similarly on other deeply-liquid majors during their own confirmed bear regimes
• Timeframe: 4h (entry signal); 4h trend indicators (regime gate)
• Regime gate (ALL three required):
  • EMA50 / EMA200 - 1 < -0.06 (≥6% separation = deep structural downtrend, not a fresh cross)
  • ADX(14) > 25 (trend strength confirmed)
  • close.pct_change(30) < -0.10 (last 30 bars = ~5 days, actual downside momentum)
• Entry (short): close < lowest_24_bar_low AND regime gate satisfied
• Exit (any of):
  • close > highest_6_bar_high (24h ceiling break — local reversal)
  • 2 consecutive bars with RSI > 55 (sustained rebound)
  • Trailing stop fires (Phase 2 — see the dsl-exit-engine skill)
• Stops: Phase 1 hard stop at -5%; Phase 2 trailing activates at +3%, trails 2% behind peak

Honest framing

This strategy only fires during confirmed strong-bear regimes. In bull markets, sideways markets, and weak bears it will trade rarely or not at all — by design. Do not "improve" by loosening the gate; the loose-gate version (without triple confirmation) lost money in the same window.

The 100% backtest win rate is partly a function of sample size (6 trades). The honest expectation is ~60-75% win rate with similar expectancy when the gate is properly confirmed across longer windows.

Pair this strategy with bollinger-reverter-4h (the chop-regime sibling) for full-spectrum coverage — they fire on mutually exclusive regimes.

Tunables

Parameter	Range	Effect
Regime EMA separation	-0.04 to -0.08	Looser = more trades, more chop noise; tighter = fewer, cleaner
Regime ADX threshold	20 - 30	Higher = more selective trend confirmation
Regime return lookback	20 - 40 bars	Window for "actual momentum" check
Donchian lookback (low)	18 - 36	Length of structural floor
Exit lookback (high)	4 - 8	Tighter exit = faster wins, more giveback
Trail activate	0.02 - 0.04	Where Phase 2 kicks in
Trail offset	0.015 - 0.025	Tightness once activated

Known failure modes

• Fresh bear regimes that haven't yet triggered the 30-bar return < -10% threshold: strategy waits until momentum is established, missing the first leg
• Whipsaw within a strong bear: a sharp counter-rally past the 6-bar high exits the trade right before the resumption. This is the price of having tight exits
• Alts with low liquidity: Donchian lows can be set by a single liquidation wick; restrict to majors

Pairing

• Designed to coexist with the bollinger-reverter-4h skill (the chop-regime sibling)
• Uses the triple-gate pattern from the regime-overlay skill
• Uses the Phase 2 trailing stop from the dsl-exit-engine skill

Deployment recommendation

Run as its own sub-account so the regime gate's "trade nothing for weeks" behavior doesn't fight a mean-reversion strategy in the same wallet. See your Superior Trade account setup for sub-accounts.
