Hyperliquid BTC Impulse-Bar Continuation, Long-Short (Single-Instrument Perp, 1H, Pure OHLCV, ATR-Relative Directional Impulse Entry, Tight ATR Stop, Chandelier-Trailed Winners, Time-Stop, Low-Parameter)

A LONG-SHORT, SINGLE-INSTRUMENT, pure-OHLCV intraday MOMENTUM-CONTINUATION strategy on BTCUSD.HYPERLIQUID perpetual futures (1-HOUR bars). It transplants the factory's SINGLE repeatedly-VALIDATED edge — directional impulse-bar continuation (the SOL sibling reached paper_stage at Sharpe ~0.69; the ETH/SOL/BTC time-series-momentum siblings passed) — onto the most under-represented venue in the portfolio: HYPERLIQUID (5.7% vs the >=20% live-trading quota, and where the factory is shifting live execution). It is a FRESH framing within that validated family, not a duplicate: the impulse-continuation mechanism has been proven on SOL and ETH but NOT on BTC (BTC currently only carries a 1D time-series-momentum strategy, not a 1H impulse-continuation one), and never on the HYPERLIQUID venue. This deliberately AVOIDS the premise that just failed on HL: the abandoned ETH opening-range-breakout died because equity-market session-handoff structure (Asia/EU range -> US-session resolution) does not transfer to crypto's 24h tape. Impulse continuation makes no time-of-day assumption — it reacts to information/liquidity shocks whenever they occur. The impulse threshold is ATR-RELATIVE so the identical logic self-calibrates to BTC's lower absolute volatility versus SOL. Pure OHLCV means zero supplementary-data dependency (sidestepping the funding/option-settlement data failures), BTC/HL has clean multi-year 1H history (dodging the earlier HL-alt data-availability failures), and the design is held to 4 core parameters to stay inside the factory's validated, non-overfit envelope.
