A LONG-SHORT, single-instrument, pure-price MOMENTUM-CONFLUENCE trend follower on ATOMUSDT.BINANCE (USD-M perpetual), 4H single-bar construction with a daily trend confirmation. This is an EVIDENCE-DRIVEN asset selection following the session's single most informative result: the ADA dual-TF confluence NEAR-MISS, which was 'the strongest dual-TF candidate the factory has produced and the ONLY one to emphatically clear significance' (deflated_sharpe 1.0 vs expected-max 0.56, optimized Sharpe 1.75, positive CI-low). That result splits the confluence family by ASSET PROFILE: it FAILS on high-beta/fat-tailed names (SOL 0.79, AVAX 0.34, XRP/DOGE/LTC no-edge) and CLEARS on smooth, MODERATE-volatility large-cap L1s (BTC survivor 1.99; ADA 1.75). ATOM (Cosmos) is squarely in the ADA class: a liquid large-cap L1 with ~5y Binance USD-M history, moderate ~4-5% daily vol (not memecoin fat tails), and clean multi-week directional legs (the 2021 run to ~$44, the 2022–2024 secular decline, subsequent swings) that the confluence mechanism harvests. It is distinct from the queued DOT port (different L1 ecosystem, different trend timing) and applies the exact mechanism + vol-scaling that produced the ADA significance-clearing result. NOT a mean-reversion fade (L53), NOT a squeeze breakout (L54), NOT a channel breakout (outlier class), NOT a cross-sectional basket (L52), NOT calendar/session (both falsified net-losing this session), NOT a NON-PRICE-feed gate (L46), NOT options/COIN-M (L50/L51). Fills the long-short gap (13.5% vs 86% long-only). To match the ADA construction and resist overfit: single 4H bar type, 3 params, fixed fast-EMA, volatility-scaled sizing (part of the ADA winner). Risk profile: ~1.5% equity risk/trade via ATR stop; vol-scaled notional = risk_budget / (atr_mult * ATR_4H) capped at 25% of equity*leverage; 2x leverage cap (reads self.config.leverage). Exactly 3 tunable parameters (slow/fast EMA ratio, daily-trend EMA length, ATR trailing multiple).
