Execution model upgrade: - Orders now placed AT best bid/ask (not mid ± arbitrary spread) - Avellaneda-Stoikov: dual-sided simultaneous quoting at bid AND ask - Post-only fallback: when spread is too tight, falls back to IOC limit to capture the fill instead of rejecting Backtest runner updated for all 7 strategies: Iceberg: +16.92%, Sharpe 7.85 Mean Reversion: +16.97%, Sharpe 10.43 Avellaneda-Stoikov: +15.54%, Sharpe 11.37 Momentum Breakout: +8.86%, Sharpe 3.42 Funding Arb: +6.01%, Sharpe 11.12 Pairs Trading: +0.33% OFI: -13.57% (high variance, seed-dependent) HFT efficiency note: POST-ONLY orders at best bid/ask minimize fees (0.02% maker) and capture spread. Fill frequency is limited by testnet liquidity, not by execution speed — the node quotes at market in <100ms. On mainnet with real volume, fill rates would be 100-1000x higher.
