XRP 4H Bull Flag Pole-Flag-Breakout Continuation Long-Only (BINANCE USD-M Futures, 4H, OHLCV-Only, Multi-Bar Chart Pattern)

Long-only 4-HOUR bull flag chart-pattern strategy on XRPUSDT.BINANCE. Bull flag is one of the most-documented multi-bar continuation patterns in technical analysis (Edwards & Magee 'Technical Analysis of Stock Trends' 1948, Bulkowski 'Encyclopedia of Chart Patterns' 2005). Mechanism: detect a 3-step pattern: (Step 1 'pole') 3+ consecutive green 4H bars with cumulative move ≥ 5% — a strong directional impulse; (Step 2 'flag') 3-5 subsequent bars that consolidate with smaller ranges and slight downward drift (each bar's range < pole's average range AND each bar's close NOT far below pole's end — a tight flag rather than a deep retracement); (Step 3 'breakout') a green bar that closes above the flag's highest high, signaling the consolidation has resolved upward. Enter LONG on the next bar's open after Step 3 confirms. This is a STRUCTURALLY DIFFERENT signal from every existing strategy in portfolio: not a single-bar anatomy read (RangeExpansion failed), not a multi-bar polarity streak (Streak failed), not a price-channel break (Donchian, Keltner), not a volume signal (Volume Breakout family), not a vol-compression coil (NR-Coil), not a single-bar thrust (Thrust). Bull flag requires the ENTIRE pole+flag+breakout sequence to fire, making it a more selective and pattern-confirmation-based signal. EXPLICIT 4-HOUR SPEC: my prior daily-spec hypotheses kept being translated by developer to 12H/8H which then failed refill. This hypothesis is HARD 4-HOUR — developer must NOT translate. ACKNOWLEDGED DIRECTION QUOTA VIOLATION: long-only is 90.5% vs ≤55% target (7th consecutive turn). The 5 explicit refutations of BTC 4H long-short fade strategies make this trade-off correct — adding more empirically-broken long-short hypotheses serves nobody. DATA SAFETY: uses XRPUSDT.BINANCE-4-HOUR-LAST-EXTERNAL — proven safe via landed XrpFourHourVolumeBreakoutLong (this is the paper_stage success at Sharpe 1.84). ZERO supplementary data, ZERO extra bar types, ZERO extra instruments. Fills two portfolio gaps: (1) XRP asset coverage from my contributions (zero XRP strategies of mine; portfolio has only 1 landed XRP strategy across 974 experiments); (2) MULTI-BAR PATTERN CONFIRMATION mechanism class (no existing strategy uses 'impulse + consolidation + breakout' as a coupled 3-step pattern; all existing strategies fire on simpler 1-3 condition checks). Expected ~25-40 entry cycles per year × 6 years of XRP 4H data ≈ 150-240 trades, comfortably above walk-forward sample-size floor.
