A LONG-SHORT, single-instrument, pure-OHLCV INTRADAY SESSION-MOMENTUM continuation strategy on ETHUSDT.BINANCE USD-M perpetual using 1-HOUR bars. Each UTC day it anchors an OPENING RANGE over the first few hours (from the 00:00 UTC daily/funding-clock boundary), then enters in the direction of the FIRST confirmed breakout of that range and rides the intraday continuation, flattening by end of day. This is a GENUINELY NEW mechanism (the analyst's explicit directive after the impulse-continuation family mapped its boundaries: promoted on ETH/SOL, FAILED on BTC/LINK/XRP/HL), distinct from every dead/blocked path: it is NOT a single-large-impulse-bar trigger (that family is saturated/asset-specific), NOT a daily-trend or relative-momentum majors-basket (all correlated re-expressions of the promoted AbsoluteMomentum, dead), NOT reversion (dead), NOT cross-venue funding carry (fee-squeezed), NOT options (engine-blocked), NOT sub-1H (fee-dominated). It is ALSO distinct from the regime-broken daily Donchian breakout BASKET: that was multi-instrument, multi-day trend-initiation whipsawed by daily chop; this is single-asset, intraday, anchored to a fixed session reference, and FLAT every night — so it captures intraday session-momentum (documented Asia/US-session directional drives and the daily-funding-clock effect) and resets daily rather than riding multi-day trends. It deliberately keeps the SAME validated core fact the impulse family exploits — crypto exhibits short-horizon CONTINUATION — but via an orthogonal, time-anchored trigger, on the asset where intraday continuation is most robustly proven (ETH, the promoted impulse asset), to maximize the edge prior. It is fee-survivable where sub-1H died (<=1 trade/day, flat EOD -> ~250 trades/yr, low fee incidence; a confirmed session break typically runs well past the ~0.10% RT) and validatable where HL intraday died (Binance USD-M ETH has deep 1H history -> ~1500 trades over ~6yr to populate the walk-forward). Engine-safe: discrete enter-once/exit-once, single position, hard-capped notional, no continuous rebalance/vol-scaling. Three core parameters.
