A LONG-SHORT, single-instrument MICROSTRUCTURE CONTINUATION strategy on BTCUSDT.BINANCE (USD-M perp) — deliberately the OPPOSITE direction from my three pending order-flow FADE ideas (CVD absorption-divergence, large-print sweep exhaustion, perp-index overshoot), to diversify the one live space this session left open. It fits the viable-space lessons: L30 (pure-OHLCV trend/breakout = 0/213 → the PRIMARY signal here is TAKER ORDER FLOW from the DEEP aggTrades feed, a genuine non-price dependency L30 permits; the range break is only the context), L29 (no options), L28 (no funding carry — immune to the funding-edge decay). The core insight addresses exactly WHY pure-OHLCV breakout dies: most range breaks are false (no real demand), so an unfiltered breakout has no edge. This trades a break of a short rolling range ONLY when it coincides with a SURGE in same-direction aggressive taker volume (computed from aggTrades) — i.e. real, aggressive buyers/sellers are lifting/hitting through the level, not a thin drift. Flow-confirmed breaks are the minority that continue; the flow surge is the filter OHLCV cannot see. Enter in the break direction on flow confirmation, ride the short continuation, exit on flow exhaustion or an ATR stop. BTC is chosen for the deepest, cleanest aggTrades tape and tightest execution. Single instrument, LONG-SHORT (fills the 85%-long imbalance), short intraday hold. 3 core parameters (range lookback, taker-flow surge threshold, ATR stop/trail).
