BCH–LTC Common-Shock Relative Overreaction, Cross-Venue Long–Short

Hypothesis

Trade BCHUSD.HYPERLIQUID against LTCUSDT.BYBIT on synchronized 4-HOUR bars. Test whether a large relative displacement following a shared directional move partially reverses after the initial sector repricing. This is cross-asset convergence, not same-coin venue arbitrage or funding carry. Enter with market orders at the completed signal bar's close; this is the registry's faithful equivalent to next-bar-open execution on continuous markets. Cross-venue fills are sequential, not atomic. Use only overlapping historical coverage, with no timeframe substitutions or forward-filled prices. Fees use the documented base taker rates: [Hyperliquid fees](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/fees), 0.045% per fill, and [Bybit perpetual fees](https://www.bybit.com/en/help-center/article/?id=000001584), 0.055% per fill. No supplied library excerpt describes this mechanism sufficiently for a faithful source port.
