Leverage-Regime-Gated Momentum, Long-Short (Single-Instrument AVAXUSDT.BINANCE USD-M — Trade 4H Price Momentum ONLY When Perp FUNDING Magnitude Signals a LEVERAGED / Trending Regime; Stand Aside When Funding Is Flat = Range Regime, Trailing-Stop Winners, 2-Parameter)

A LONG-SHORT, SINGLE-INSTRUMENT, SINGLE-VENUE momentum strategy on AVAXUSDT.BINANCE USD-M that leans on the factory's ONLY proven archetype — 4H momentum with trailing stops (the single Sharpe-~2 survivor) — but gates it with a genuinely ORTHOGONAL, data-SAFE REGIME filter that is NOT a second price series and NOT the taker-flow confirmation that already collided-and-died. The gate is perpetual FUNDING MAGNITUDE, the one supplementary feed confirmed dense and reliable multi-year in the sandbox. Economic premise: momentum persists in LEVERAGED, directional regimes and mean-reverts / whipsaws in balanced ones. When funding carries a strong bias (large |funding| vs its own rolling norm), the market is leverage-driven and one-sided — the environment where trends extend and momentum pays. When funding sits near zero (balanced books), price action is choppy and momentum entries bleed on whipsaw. So we take momentum trades ONLY inside the leveraged regime and stand flat otherwise. This is deliberately the MIRROR of the pending neutral-funding-gated spot mean-reversion (that trades reversion in the FLAT-funding range regime; this trades continuation in the BIASED-funding trend regime) — opposite regime, opposite mechanism, opposite venue/direction — and a different family from the dead positioning-contrarian, forced-flow-reversal, and funding-euphoria-de-risk lines. Data-safe: funding is multi-year-dense; single venue + single instrument on 4H bars → all data jointly available in Layer-3 (no cross-venue, options, OI, or liquidation feed to fail). Deliberately 2-parameter to resist the overfit deaths that dominate the log.
