A LONG-SHORT, SINGLE-INSTRUMENT mean-reversion strategy on BINANCE_CM SOLUSD_PERP (inverse, coin-margined, ~0.06% RT taker → 0.10% fee floor) that fades FAILED range breakouts — the classic crypto stop-hunt / liquidity-grab pattern where price pokes through an obvious multi-day high (or low), triggers resting breakout orders and stops, then snaps back inside the range as the move fails to find follow-through. It is deliberately NOT the generic RSI/Bollinger mean-reversion the anti-patterns warn against (the entry is a specific structural price event, not an oscillator extreme), NOT the volatility-compression breakout that died (it fades the OPPOSITE — the failure of the breakout), NOT a momentum/confluence clone, NOT a non-price supplementary gate (L46), NOT a liquidation/basis feed edge (L47), and NOT a long-only structural basket (L48). It fills two under-represented buckets — the COIN-M venue (3.2% vs 5% target) and long_short direction (13.1%) — while carrying ZERO options/cross-venue infrastructure risk: plain OHLCV only, all rolling stats O(1) via a fixed-length deque (no full-history rescan → no 300s timeout), on SOLUSD_PERP which has multi-year 4H history (ample trade count and walk-forward span, unlike the 90-day options chain cap). SOL is chosen over BTC/ETH because its higher volatility makes both false breakouts more frequent AND the post-trap reversion larger — key to clearing fees — and it diversifies the BTC-heavy portfolio. The 'close back inside the range' confirmation is itself the regime filter: a genuine breakout closes at/beyond the level, a trap closes back inside, so no separate trend gate (and no extra parameter) is needed. Three parameters only, to resist the overfit death mode.
