A LONG-SHORT, SINGLE-INSTRUMENT, SINGLE-VENUE strategy on SOLUSDT.BINANCE USD-M perpetual. The orthogonal signal is the TAKER buy/sell aggressor imbalance (taker_ratio supplementary feed, orthogonal to the price series and not a re-derivation of trend — satisfies L42). No taker-flow strategy appears anywhere in the failure log, so this is a genuinely fresh family distinct from the saturated cross-sectional-momentum, funding-crowding, OI-confirmed/OI-flush, and premium-capitulation graveyards. Mechanism: when aggressors are overwhelmingly lifting offers (taker_buy_ratio at a multi-day extreme) WHILE price is spiking up, that is late-stage euphoric market-order chasing that consumes resting ask liquidity and leaves price extended above where passive participants will support it — a short-term reversal down follows once the aggressive flow exhausts. Symmetric on the downside: extreme taker-SELL dominance during a flush = panic market-selling into thin bids, over-extends price to the downside, snaps back. The strategy fades the aggressor: extreme taker-BUY + up-move → SHORT; extreme taker-SELL + down-move → LONG. This is exhaustion/liquidity-consumption, not momentum continuation (the opposite of a taker-flow breakout book). Single-venue, single-instrument — no cross-venue/second-leg joint-availability problem (L44), no options/IV feed (L43). SOLUSDT chosen for high realized volatility (reversal targets clear the 0.10% USD-M round trip with wide margin) and to diversify away from the 2%-survival BTC tag. Kept to 3 parameters to resist the overfit deaths dominating the log. Instruments: ["SOLUSDT.BINANCE"]. venue_type: futures. data_requirements: ["ohlcv", "taker_ratio"].
