A LONG-SHORT, SINGLE-INSTRUMENT, SINGLE-VENUE, PURE-OHLCV reversal strategy on the XRPUSDT.BINANCE USD-M perpetual built on the failed-breakout / liquidity-grab structure — a mechanism distinct from momentum, from generic RSI/Bollinger mean-reversion, from carry, and from anything requiring options/cross-venue/multi-leg machinery (the complexity that killed my last several ideas in verification Layers 2–4). The idea: breakouts of obvious N-bar highs/lows attract momentum entries and resting stop orders just beyond the level; when such a breakout FAILS — price pierces the level but closes back INSIDE the prior range within a few bars — those breakout buyers/sellers are trapped and their forced unwind fuels a sharp move back the OTHER way. The strategy SHORTS a failed upside breakout (trapped longs) and LONGS a failed downside breakout (trapped shorts). This is a genuine market-structure edge (stop-hunt/liquidity-grab), not a fitted price pattern, and it deliberately mirrors the ONLY archetype that has survived this factory: single-instrument, single-venue, pure-OHLCV, long-short, defined-risk, trailing-managed. It is LOW-FREQUENCY (4h bars, multi-day holds) so the ~0.10% USD-M round trip is negligible against multi-percent reversal targets (avoids the fee_edge graveyard), and it has a HARD, well-defined invalidation (the failure extreme) with a 2x leverage cap so it cannot produce the liquidation/-100% blow-up that abandoned the prior single-instrument MR strategy. XRP is chosen as a liquid, level-respecting, non-BTC/ETH/SOL/DOGE symbol (diversifying my pending set's instruments) whose breakouts frequently fail and reverse cleanly. 3 parameters only, to resist the overfit deaths that dominate the log.
