Strategy: Momentum · Breakout

When to use

A user asks for "breakout", "momentum", "trend following", "buy new highs", "Donchian breakout", "range expansion". Single or multi-pair, hour-scale, with a trailing stop.

Honest framing

The reference backtest was unprofitable (36% WR, −0.95% PnL) on BTC/USDC:USDC 1h Jan-May 2026 — but BTC fell −13% in that window. Long-only breakouts in a downtrend are structurally a losing setup. The strategy is correct; the regime was wrong.

Two practical paths to make this work:

• Add a regime filter (e.g. only enter when close > ema_200 on the higher timeframe).
• Run on a wider, multi-pair scan so trending alts contribute even when BTC is weak.

Backtest reference

Window	BTC/USDC:USDC 1h, 2026-01-01 → 2026-05-01 (BTC −13%)
Trades	64
Win rate	36%
Wallet PnL	−0.95%
Backtest ID	01kqypw5bqsaezpgm8pxcrpvyb

Trailing stop kept losses small per trade, but the entry signal fired into too many failed breakouts in a downtrend. Re-run on Q4 2025 or a trending alt to see the strategy in its native regime.

}

The trailing-stop block is what makes this template worth keeping — it locks in profits once a breakout extends past +2.5%, then trails 1.5% behind.

Tunable parameters

Knob	Effect
12 (rolling high length)	Shorter (6) → more entries, lower-quality breakouts. Longer (24) → fewer, higher-conviction.
volume > vol_avg20	Stricter (> vol_avg20 × 1.5) → only volume-confirmed breakouts.
trailing_stop_positive_offset (0.025)	Higher → trailing stop activates later, gives more room. Lower → locks in earlier, exits more often.
trailing_stop_positive (0.015)	Tighter trail → exits closer to highs, more stops out.
low_6h exit	Shorter window → faster invalidation. Longer → patience but bigger giveback.

Variants worth testing

• Higher-timeframe regime filter: only enter when 1d close > 1d ema_50. Removes trades in clear downtrends (would have killed most of the −0.95% in the reference).
• Donchian channel proper: rolling 20-bar high (instead of 12) is the textbook breakout. Test with longer rolling window.
• Multi-pair (top 30 perps): replace StaticPairList with VolumePairList filtered to top 30 by 24h volume. Diversifies regime risk.
• Add ATR-scaled position sizing: smaller stake when ATR is high (more risk per trade) keeps risk-per-trade flat.

Common pitfalls

1. Long-only in downtrends. As shown by the reference. Add a regime filter or accept the strategy will lose money in bear markets.
2. process_only_new_candles = False. Default True is correct here; setting it false fires on every tick during backtest dry-run and triple-counts entries.
3. Conflict between minimal_roi and trailing stop. Setting minimal_roi: { "0": 0.05 } exits at +5% before the trailing stop activates at +2.5% offset. Use {"0": 100.0} and let the trailing stop run.
4. startup_candle_count too small for ATR-14. ATR needs 14 bars of warmup; the default 30 is fine. If you switch to ATR-100, bump startup to 100+.
