BTC 4H Multi-Bar Intra-Range Close-Position Consistency Long (Stealth-Bid Structural Pattern)

A long-only, single-instrument, single-timeframe strategy on BTCUSDT.BINANCE 4H bars implementing a structural intra-bar STATISTIC across multiple bars: the average position of the close within each bar's high-low range, computed over the last 5 bars. When this average is consistently in the upper third (>= 0.65) AND the current bar makes a new 5-bar high AND the long-term trend filter holds, the pattern signals 'stealth bid' accumulation — buyers systematically pushing each bar's close near its highs over multiple consecutive bars, indicating sustained buying pressure without the bars themselves making dramatic moves. Critically distinct from every existing pipeline entry: (a) NOT a Donchian breakout (uses position WITHIN bar ranges, not channel breaches on bar extremes); (b) NOT a volume-z signal (uses intra-bar close geometry, not transaction volume); (c) NOT a failed-breakdown reclaim (uses consistency of close positions, not breakout-and-reverse); (d) NOT a candlestick pattern (aggregates 5 bars statistically rather than recognizing single-bar shape); (e) NOT Williams %R (which uses multi-bar high/low extremes; this uses close position within EACH BAR's own range, averaged). The mechanism captures a regime of sustained buying interest that's invisible to channel-breakout strategies (no dramatic single-bar move required) and invisible to volume strategies (volume can be normal). Long-only because (i) sustained close-in-upper-third over multiple bars indicates bullish bias, (ii) the trend gate prevents fading downtrends, (iii) shorts on crypto majors empirically refuted. Single-instrument BTCUSDT.BINANCE 4H — confirmed-working bar type (BtcFourHourVolumeBreakoutLong + BTCFailedBreakdownReclaimLong + BTCVolumeConfirmedDonchianCalmVolLong + BTCVolumeConfirmedDonchianAntiChopLong all validate this instrument). NO secondary instruments — directly avoids the multi-instrument audit_stale failure mode.
