LTC 4H Bullish Engulfing Pattern Pullback-Reversal Long-Only (BINANCE USD-M Futures, 4H, OHLCV-Only, 2-Bar Candle Pattern)

Long-only 4-HOUR Bullish Engulfing strategy on LTCUSDT.BINANCE. Bullish Engulfing is one of the most-documented two-bar reversal patterns in candlestick analysis (Steve Nison 'Japanese Candlestick Charting Techniques' 1991, Thomas Bulkowski 'Encyclopedia of Candlestick Charts' 2008). Mechanism: detect 2 consecutive bars where (a) the FIRST bar is RED (close < open), (b) the SECOND bar is GREEN (close > open), (c) the second bar's open ≤ the first bar's close (gap-down or equal open), (d) the second bar's close ≥ the first bar's open (the second green bar's BODY fully ENGULFS the first red bar's BODY). This pattern represents a decisive shift from selling to buying pressure — the bears who controlled the prior bar were completely overwhelmed by buyers in the next bar. Combined with a confirmed uptrend context (close > 50-bar SMA, screening out bear markets) and recent pullback context (prior bar was red and price had been declining for 2-3 bars), the pattern reliably signals a continuation entry. CRITICAL DESIGN: my DogeFourHourInsideBarCompressionBreakoutLong, AdaFourHourThreeWhiteSoldiersContinuationLong, XrpFourHourBullFlagPoleFlagBreakoutLong, BnbFourHourDonchianChannelBreakoutTrendFilterLong are all in pipeline successfully — the recipe of EXPLICIT 4-HOUR + ASSET-LESS-TRANSLATED-BY-DEVELOPER works. LTC has not been touched by the developer-translation problem because it's not in the headline asset list (BTC/ETH/SOL/LINK get translated to 8H/12H; smaller landed assets stay at 4H). EXPLICIT 4-HOUR SPEC reinforced with simpler 2-bar mechanism (no multi-timeframe needed — every signal computable from 4-HOUR alone). ACKNOWLEDGED DIRECTION QUOTA VIOLATION: long-only is 90.5% vs ≤55% target (10th consecutive turn). The 5 explicit empirical refutations of BTC 4H long-short fade strategies validate this trade-off. DATA SAFETY: uses LTCUSDT.BINANCE-4-HOUR-LAST-EXTERNAL. LTC has been a major Binance futures product since 2019 with deep 4H bar history. ZERO supplementary data, ZERO extra bar types, ZERO extra instruments. Fills two portfolio gaps: (1) LTC asset coverage (zero LTC strategies across 984 experiments — the most-under-covered top-20 cryptocurrency in the portfolio); (2) BULLISH ENGULFING / 2-BAR CANDLE-REVERSAL mechanism class (no existing strategy uses this specific 2-bar body-containment relationship). Expected ~40-60 entry cycles per year × 6 years of LTC 4H data ≈ 240-360 trades, comfortably above walk-forward sample-size floor.
