From 9cf871be46033e666d4003952c3b37961bc5c4cd Mon Sep 17 00:00:00 2001 From: ramseshk Date: Thu, 6 Aug 2026 09:47:21 +0000 Subject: [PATCH] Fix order pricing: 1-tick advantage at best bid/ask + process guard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A-S was quoting at best bid/ask (0% win) — orders filled but 0.04% round-trip maker fee exceeded spread capture. Now: bid+1 / ask-1 = captures spread minus 1 tick each side. Signal-driven strategies: same 1-tick pricing instead of 0.03% offset that crossed the book or sat too far away. Added fcntl file lock to prevent duplicate live nodes. Added IOC fallback (market-crossing) when post-only rejected. A-S win rate: 0% → 25% (first 8 trades with new pricing) --- live/node.py | 72 +++++++++++++++++++++++++++++++++------------------- 1 file changed, 46 insertions(+), 26 deletions(-) diff --git a/live/node.py b/live/node.py index cfb82bb..127d132 100644 --- a/live/node.py +++ b/live/node.py @@ -34,11 +34,11 @@ STRATEGIES = { "Order Book Imbalance": {"allocation":100.0,"instrument":"BTC-USD-PERP","pnl":0.0,"pnl_pct":0.0,"position":0.0,"trades_today":0,"wins":0,"win_rate":0.0,"status":"idle","size":0.000200,"fee_paid":0.0,"signals":[],"type":"reversal","description":"L2 bid/ask volume skew — buys when bids dominate, sells when asks dominate."}, "Iceberg Detection": {"allocation":100.0,"instrument":"BTC-USD-PERP","pnl":0.0,"pnl_pct":0.0,"position":0.0,"trades_today":0,"wins":0,"win_rate":0.0,"status":"idle","size":0.000210,"fee_paid":0.0,"signals":[],"type":"momentum","description":"Detects whale TWAP accumulation — follows smart money flow."}, "Funding Rate Arb": {"allocation":100.0,"instrument":"BTC-USD-PERP","pnl":0.0,"pnl_pct":0.0,"position":0.0,"trades_today":0,"wins":0,"win_rate":0.0,"status":"idle","size":0.000220,"fee_paid":0.0,"signals":[],"type":"carry","description":"Delta-neutral carry — holds spot, shorts perp, collects funding."}, - "Pairs Trading": {"allocation":100.0,"instrument":"ETH-USD-PERP","pnl":0.0,"pnl_pct":0.0,"position":0.0,"trades_today":0,"wins":0,"win_rate":0.0,"status":"idle","size":0.006,"fee_paid":0.0,"signals":[],"type":"stat_arb","description":"BTC/ETH ratio Z-score — trades when spread exceeds 1.5σ."}, + "Pairs Trading": {"allocation":100.0,"instrument":"ETH-USD-PERP","pnl":0.0,"pnl_pct":0.0,"position":0.0,"trades_today":0,"wins":0,"win_rate":0.0,"status":"idle","size":0.012,"fee_paid":0.0,"signals":[],"type":"stat_arb","description":"BTC/ETH ratio Z-score — trades when spread exceeds 1.5σ."}, "Avellaneda-Stoikov": {"allocation":100.0,"instrument":"BTC-USD-PERP","pnl":0.0,"pnl_pct":0.0,"position":0.0,"trades_today":0,"wins":0,"win_rate":0.0,"status":"idle","size":0.000230,"fee_paid":0.0,"signals":[],"type":"market_making","description":"Dual-sided quoting at best bid/ask — captures spread via stochastic control.
