Third entry archetype: completion of classical chart patterns (double
bottom/top, H&S top / inverse H&S, bull/bear flag) — the tight canon
with the strongest documented stats. New chart_patterns.py detector
module (pure functions, ATR-unit geometry, closed-bar slices only,
first-close-beyond trigger discipline so a breakout fires exactly
once and never repaints).
Pipeline step 10 in analyze_from_dataframes: fills only empty setup
slots, allows weak-composite F grades (normal at reversal completion)
but inherits session/day blocks, mirrors MTF-opposition + SELL
vol/hour + M5 protections. Geometry: SL = pattern anchor -/+ 0.5 ATR
(min $8), TP1 = measured move, $9 spread gate, trailing exit does the
real work. Strategy tag XAU_CP.
cp_enabled defaults to False everywhere — per-TF adoption happens in
pair_signals/xauusd.py only after the standard validation rule passes.
Backtester: --cp / --cp-patterns flags to test the candidate, XAU_CP
tag recognition.
Suite: 183/183 (21 new tests: detectors, trigger discipline,
invalidation, gates, pipeline, default-off safety).
