A LONG-SHORT, single-instrument microstructure strategy on DOGEUSDT.BINANCE (USD-M perpetual, 15m decision bars) that trades the direction of aggressive taker order flow BEFORE price fully reprices it. DOGE is deliberately chosen: it is one of the most retail-driven, aggressor-heavy perps on Binance, so its taker buy/sell volume imbalance carries an unusually strong short-horizon directional signal relative to majors. The traded instrument is the perp; the SIGNAL is the Binance taker buy/sell aggressor-volume ratio (supplementary `taker_ratio` feed, multi-year), NOT raw OHLCV. This fills the two furthest-from-target diversity buckets the current portfolio allows me to reach without landing in a known graveyard: short_1m_15m horizon (8.6% vs >=10% target) and long_short direction (14.3% vs a >=55% ceiling that long_only blows through at 85.7%). It also escapes the pure_ohlcv survival trap (1% of 80) by depending on a genuine microstructure feed, and it is NOT a Hyperliquid strategy (L11: 0/84 HL survival), NOT an options strategy (L23), NOT a cross-sectional basket (L12), NOT a funding-level signal on majors (L13), NOT liquidation-feed dependent (L3), and NOT a cross-venue carry (L1). Mechanism: at each 15m close compute the rolling taker-buy fraction TB = taker_buy_vol / (taker_buy_vol + taker_sell_vol) over a short window, and its percentile within a long trailing distribution. When aggressor flow reaches a decile extreme (heavy one-sided market-order pressure) AND the bar's realized price move over the same window is still SMALL (flow has accumulated but price has not yet repriced it -> the flow-leads-price edge), enter in the flow direction. Deliberately low-parameter (3 knobs) because overfit is the #1 cause of death here (233x).
