A LONG-SHORT, SINGLE-INSTRUMENT, DAILY contrarian strategy on BTCUSDT.BINANCE (USD-M perpetual) that fades EXTREME perpetual funding — a direct, mechanically-driven measure of leveraged-positioning crowding — using funding ONLY as a SIGNAL (not as carry/PnL), so there is no funding-accrual, cross-account, or hedge-leg issue. This is the DELIBERATE, analyst-endorsed REVISION of the Hyperliquid funding-extreme contrarian run that failed PURELY on the ~155-day HL data wall: the analyst's own meta-note said 'the funding-as-signal contrarian-reversion mechanism is reasonable and was cleanly implemented... if this mechanism is pursued, it needs a venue/instrument with multi-year history so walk-forward and holdout span real regimes.' Binance USD-M BTC funding history is multi-year (2020+), directly removing the root cause of that failure. It is engineered around every other confirmed landmine: SINGLE-INSTRUMENT / SINGLE-VENUE / SINGLE-ACCOUNT (no multi-instrument equity/return aggregation artifact); DAILY bars (NOT the intraday fee-bleed horizon that wiped the SOL VWAP and ETH taker fades); and — critically — it is explicitly designed with FAVORABLE PAYOFF GEOMETRY to avoid the small-TP/large-stop inversion that sank the SOL VWAP fade: the winner is allowed to run to funding-NORMALIZATION (a potentially large reversion), while the loss is a bounded ATR stop, so avg_win is structurally >= avg_loss rather than the destructive opposite. It is distinct from the existing EthPerpDailyFundingConfirmedTrendLS (which trades WITH the trend when funding CONFIRMS); this FADES funding EXTREMES (opposite logic), on BTC. It is also NOT a single-name price-trend re-expression (the analyst asked to stop those) — it is an orthogonal, crypto-native, positioning-based mechanism. Low parameter count to resist overfitting; moderate thresholds so entries fire adequately (avoiding the taker-flow no-trade failure).
