A LONG-SHORT, single-instrument INTRADAY MOMENTUM-breakout on SOLUSDT.BINANCE (USD-M perp, 15m bars) that trades the CONTINUATION of genuine range-expansions — the deliberate OPPOSITE polarity of the intraday VWAP/z-score reversion FADES that keep dying (the ETH VWAP port confirmed negative on 6,130 trades; my OI fade confirmed negative on SOL). Fades of intraday deviations have no edge on crypto perps; this instead trades WITH the breakout, betting on short-horizon momentum continuation once volatility genuinely expands. It fills the under-represented SHORT horizon bucket (short_1m_15m 8.8% vs >=10% target) with a NON-fade mechanism, and is distinct from my pending daily/4h momentum strategies (TSMOM, breakout trend-ride) by operating on 15m intraday bars. It is NOT reversion (opposite sign), NOT a basket (single name — avoids L12 multi-leg fee death), NOT supplementary-fed (pure OHLCV — avoids the taker-flow timeout and OI/liquidation data walls), NOT options/carry. The key discipline against the fee_edge death that kills intraday strategies: it fires ONLY on a volatility-EXPANSION gate (few, high-conviction signals per day, ~1-3 max), targets a wide ~1.5x-ATR continuation move that clears the ~0.10% USD-M round-trip several times over, and uses a bracketed target/stop so losers are cut fast. SOL is chosen precisely because its large intraday % range makes breakout targets big relative to fees. Only 3 parameters; O(1) incremental rolling stats to avoid any smoke-test timeout.
