A long-only, single-instrument, single-timeframe strategy on ADAUSDT.BINANCE 4H bars (the most-reliably-fresh bar type). Implements a NEW MECHANISM operating on a DIFFERENT OBSERVABLE than every existing pipeline entry: the OPEN-vs-PRIOR-CLOSE GAP. Each 4H bar has an open that may differ from the previous bar's close — this 'inter-bar gap' reflects flow that occurred between the prior bar's close timestamp and the current bar's open timestamp (in 24/7 crypto markets, this is essentially instant, but Binance Vision bar timing produces measurable gaps from rapid order flow at the bar boundary). The mechanism: detect bars where the open is meaningfully above the prior close (bullish gap >= 0.5×ATR_14), AND the current bar's close is HIGHER than its open (the gap was sustained, not faded), AND price is in confirmed uptrend. Captures inter-bar momentum injection that no intra-bar mechanism captures. Critically distinct from every existing ADA 4H mechanism: NOT Donchian breach (uses gap, not channel), NOT bar geometry (uses INTER-bar relationship, not intra-bar), NOT z-score returns (uses gap-to-ATR ratio, not return distribution), NOT autocorrelation (no temporal-correlation math), NOT range outlier (uses open-vs-prior-close, not high-low range), NOT volume signal (gap is price-only). Three-filter conjunction: bullish-gap-magnitude + sustained-close + trend-filter. Expected ~30-50 trades/year — well above walk-forward minimum.
