delta-neutral pair: |dev| > threshold (dev = spread − 60min rolling mean, de-trended) → short the expensive leg + long the cheap leg → close on convergence, timeout (10–30 min by tier), or stop-loss (2× entry or absolute bp cap). Execution: SERIAL legging — HL IOC first (slow leg, ~1s), BN MARKET on confirmed fill (eliminates partial-fill + race-skip naked-leg risk). Backtest v0.6 portfolio (full BN∩HL universe): 506% APY / $100K NAV (top 5 = 65%: ZEC/PUMP/TAO/WLFI/HYPE). Live data above is LIVE TRADING — real orders, $300 BN futures + $300 HL perps, 5x cross.
