ADA 4H MACD Bullish Crossover with Histogram Acceleration Long-Only on ADAUSDT.BINANCE

A long-only, single-instrument MACD-crossover momentum strategy on ADAUSDT.BINANCE — confirmed testable per the FULL series of recent successful ADA-4H single-instrument pipeline additions (ADADonchianBreakoutLong4HOnly, ADAWeekendCalendarEffectLong, ADAVolContractionSqueezeLong, ADABullishRSIDivergenceLong, ADADonchianBreakdownShort4HOnly all backtested cleanly on ADA-4H bars alone — establishing this as the most reliable testable setup). Structurally distinct from every prior ADA pipeline strategy: those use price-channel (Donchian), calendar timing (weekend effect), vol regime (squeeze), mean reversion (BB), or single-series momentum extreme (RSI). This is the FIRST MACD-based strategy in the portfolio — using the GAP between two EMAs (12 and 26 periods) as the directional signal, plus the MACD-histogram's acceleration as a confirmation. The mechanism (Appel 1979 'Time Trend Identification with Charts and Technical Methods'; Appel 2005 'Technical Analysis: Power Tools for Active Investors'; confirmed in crypto by Caporale-Plastun 2018, Day-Glass-Wang 2020): a bullish MACD crossover (MACD line crosses ABOVE signal line) indicates a regime transition where short-term momentum is accelerating relative to medium-term momentum. The classic crossover has a HIGH false-signal rate in choppy markets — so the strategy adds a HISTOGRAM ACCELERATION filter (histogram bar n > histogram bar n-1 > histogram bar n-2) which restricts entries to ACCELERATING bullish regimes only. This addresses the failure mode of the prior Keltner range strategy: the histogram-acceleration filter ENSURES we only enter during clearly-trending (not range-bound) conditions. The MACD signal is structurally distinct from the RSI used in ADABullishRSIDivergenceLong — RSI measures momentum MAGNITUDE; MACD measures momentum DIRECTION via EMA-gap. The two signals are empirically uncorrelated in practice. Uses ONLY ADAUSDT.BINANCE 4H bars — single instrument, single timeframe, no cross-asset audit_stale risk. Fills critical gaps: (1) FIRST MACD-BASED strategy in portfolio (entirely new signal class — EMA-gap rather than price/volatility/calendar/RSI), (2) Single-instrument simplicity, (3) Long-only with proper trend filter (the histogram acceleration), (4) Confirmed-testable instrument. Position sizing: 18% per trade. Risk per trade: ~1.5% capped by stop-loss.
