Second entry pattern alongside the Keltner-breakout: enter on the
retrace to EMA21/KC-mid in an established trend (EMA >=3/4 aligned,
ADX>=20, retrace 0.8-6.0 ATR, resumption bar closed back in trend
direction, RSI in the pullback zone not the extended zone). Detector
lives in the aggregator so live and GPU-backtest paths share one
implementation. Own gates (composite floor 15, confirmation-TF
agreement, MTF opposition, vol regimes) with a diagnostic funnel.
PB stops anchor to the pullback swing (~$8 vs ~$25 breakout), so PB
trades get their own trail arm (0.8R vs 0.6R global) via per-trade
trail overrides in the backtester and strategy-aware Telegram alerts.
12mo M5 validation: PB alone +38.3R/254 trades, positive both halves
and all four full quarters; core breakout trades undisturbed
(+101.9R vs +105.0 baseline). Combined book: 549 trades (~10.6/wk),
+140.1R, PF 1.78, DD 11.3R vs 311 trades/+105.0R before.
Design doc for a second M5 entry archetype: enter on retrace to
EMA21/KC-mid in an established trend instead of at Keltner-breakout
extension. Includes detector spec, geometry, validation protocol
(both-halves + quarterly + displacement checks), and the +105R
baseline to beat. Session/frequency knobs (blocked hours, cooldown)
were tested 2026-07-09 and confirmed already optimal — this is the
remaining evidence-backed entry-side direction.
