A LONG-SHORT, single-instrument intraday opening-range-breakout (ORB) strategy on SOLUSDT.BINANCE (USD-M perpetual, 15-minute bars). Each UTC day, the strategy defines an 'opening range' from the high/low of the first N 15m bars after 00:00 UTC (the daily funding-settlement / Asia-session boundary), then trades the FIRST clean break of that range in either direction and rides the continuation to session end. This is deliberately the OPPOSITE mechanism from the mean-reversion strategies that keep dying in this factory (XRP RSI(2), BNB Bollinger reversion, VWAP fades) — it BUYS strength and SELLS weakness rather than fading extremes — and it is horizon/direction-diverse from the long-only daily baskets that dominate the portfolio (85% long-only, 71% BINANCE-futures, only 5.4% short-horizon). It avoids every recent graveyard: no funding-level signal (L13), no liquidation feed (L3), no options (L23), no cross-sectional basket (L12), no cross-venue carry (L1), no Hyperliquid (L11), no 200-SMA regime timing. Only 3 parameters to keep overfitting risk (the #1 killer, 202x) low. Routed to BINANCE despite over-representation because short-horizon validation needs multi-year sub-hourly history, which Hyperliquid cannot provide (~2.5 weeks at 15m) and Bybit/Deribit have no catalogued SOL perp bars in our infra; the direction+horizon diversity this fills outweighs the venue count.
