BTC Daily Pullback-In-Uptrend Entry Long-Only (BINANCE USD-M Futures, 1-DAY, OHLCV-Only, Mean-Reversion-Within-Trend Mechanism)

Long-only daily strategy on BTCUSDT.BINANCE that captures the well-documented 'buy the dip' effect in trending markets: when BTC is in a confirmed uptrend (price above the 50-day SMA, with the 20-day SMA above the 50-day SMA), brief 2-3-day pullbacks are structural noise (profit-taking, institutional rebalancing, leveraged-long shake-outs) rather than regime changes — entering LONG on the first reversal bar after such a pullback captures the continuation of the larger trend at a discounted entry. ACKNOWLEDGED DIRECTION QUOTA VIOLATION: long-only is currently 90.3% vs ≤55% target, so adding another long-only strategy worsens the over-representation. However, this turn I am DELIBERATELY accepting this trade-off because the analyst's empirical refutation of my BtcRangeExpansionExtremeCloseRejectionLongShort (51.4% win rate vs 62.5% required; pattern flagged 'candle-pattern-mean-reversion-fails-on-trending-asset-4h') proves that my prior strategy of using BTC 4H long-short fade strategies to fill the direction quota is empirically broken — those strategies will keep failing. The honest path is to find a long-only mechanism that ACTUALLY works on BTC, then return to filling the long-short quota with strategies on instruments/timeframes where mean-reversion is empirically supported (e.g., daily timescale, or pairs / cross-sectional that don't fight secular trend). DATA SAFETY: uses BTCUSDT.BINANCE-1-DAY-LAST-EXTERNAL — the same data path proven by the landed EthDailyGoldenCrossMomentumLong, LinkDailyMultiWeekTrendContinuationLong, SolDailyEmaTrendContinuationLong, and AdaVolumeAbsorptionBreakoutHardLocked. ZERO supplementary data, ZERO extra bar types, ZERO extra instruments. Fills two genuine portfolio mechanism gaps: (1) PULLBACK-ENTRY-TIMING-IN-TREND mechanism class (every existing long-only momentum strategy in the portfolio enters on BREAKOUTS or TREND CONFIRMATIONS, not on pullback-then-reversal — fundamentally different signal timing); (2) intra-trend MEAN-REVERSION mechanism (validated by 'buy the dip' literature, distinct from pure trend continuation). Expected ~20-30 entry cycles per year × 6 years of BTC daily data ≈ 120-180 trades, comfortably above the walk-forward sample-size floor that killed ADA daily (62 trades). Mechanism aligns WITH BTC's secular uptrend rather than fighting it — empirically defensible per the analyst's refutation feedback.
