Event-plus-clock, single-leg, pure-OHLCV trade on the Binance USD-M BNB perpetual. Trigger: an hourly bar that (a) CLOSES above the highest high of the prior 72 hourly bars, (b) closes in the top 30% of its own high-low range (CLV > 0.7), and (c) prints volume > 1.5x the median hourly volume of the prior 168 bars. Enter long at the next open and exit on a fixed 24h clock. No gate, no supplementary feed. Mechanism without instrument or timeframe: 'buy after a high-participation bar closes decisively through a multi-day high, and hold about one day while slower momentum and stop-driven demand arrives.' Same family as the in-pipeline ADA OKX 10-day channel-break; the differences are a 3-day window, a bar-quality condition (strong close plus volume) and BNB's 6-year Binance history, so priority is 3. POINT-IN-TIME PRE-STUDY (2026-09-26, same rule on 9 perps, non-overlapping trades, 0.10% round trip deducted, 24h clock): PF > 1 on all 9. Calendar Sharpe was 0.57-1.17 (ETH 0.76, LINK 0.57, AVAX 0.66, SOL 0.77, XRP 1.03, ADA 1.14, DOGE 1.17, BNB 1.04, XRP-Bybit 0.64). On BNBUSDT.BINANCE: 398 trades from 2020-02 to 2026-09, net +0.53%/trade, PF 1.44, calendar Sharpe 1.04, net +0.16%/trade without the top 5 trades, win rate 48%. HONEST WEAKNESS: 2021 contributes most of the PnL (+2.46% mean on 72 trades). Mean per trade by year: 2022 -0.48%, 2023 +0.09%, 2024 +0.38%, 2025 -0.01%, 2026 +0.46%. Outside 2021 the edge is only about +0.1-0.2% net.
