A LONG-SHORT, SINGLE-INSTRUMENT, SINGLE-VENUE reversal strategy on the ADAUSDT.BINANCE USD-M perpetual that adds ONE genuinely new, orthogonal information source — aggressive TAKER order-flow (taker-buy vs taker-sell volume) — to a price signal, exactly the augmentation L38 permits (new information source, not a momentum clone or symbol swap). The mechanism is order-flow EXHAUSTION DIVERGENCE: a price extreme is only trustworthy if aggressive market-order flow is pushing in the same direction. When price grinds to a new local HIGH but the net taker-BUY pressure behind it is FALLING (the rally is running on passive drift / thinning aggression), the move is exhausted and prone to reverse → SHORT; mirror for a new local LOW made on WEAKENING taker-SELL pressure → LONG. This is distinct from every idea in my pending set: it is not momentum (ETH price-OI), not funding-contrarian (DOGE), not a failed-breakout structure (XRP), and not options (BTC calendar); it reads WHO is aggressive, not just where price went. It deliberately follows the only archetype that has survived this factory — single-instrument, single-venue, long-short, defined-risk, trailing-managed, low-parameter — and stays LOW-FREQUENCY on 4h bars with multi-percent targets so the ~0.10% USD-M round trip is immaterial (avoids the fee_edge graveyard). A HARD structural stop at the divergence extreme plus a 2x leverage cap make the liquidation/-100% blow-up that killed the prior single-instrument MR strategy impossible by construction. ADA is a liquid, retail-heavy, non-BTC/ETH/SOL/XRP/DOGE symbol (diversifying my instruments) whose order flow carries strong, exploitable exhaustion signatures. 3 parameters, to resist the overfit deaths that dominate the log.
