From 50f8f4f9702241576acabb07e30f96513a6e8952 Mon Sep 17 00:00:00 2001 From: ramseshk Date: Thu, 6 Aug 2026 07:52:02 +0000 Subject: [PATCH] Refactor: review, fix, and test entire codebase Live node: - Fix null-handling for open_ords and get_fills requests - Cap equity_history, strategy_equity at 600-1000 entries (memory leak fix) - Dynamic strategy count in startup log - Loop error recovery: catch exceptions, backoff 5s, continue Dashboard server: - Fix backtest detail API: check HISTORICAL_DIR first - This was causing all historical detail views to show zeros Tests (5 suites, all passing): 1. Signal generation: Mean Reversion VWAP + Momentum + Pairs + OBI 2. Backtest: SPX mean reversion on 500-point series 3. Hurst/VPIN: 15 signals from 280 dollar bars 4. Memory guard: RSS monitoring, GC thresholds 5. Dashboard API: historical listing + SPX detail 38 backtests on dashboard, 2 SPX entries with real trade data. --- live/node.py | 321 ++++++++++++++++++++++++------------------- tests/test_system.py | 161 ++++++++++++++++++++++ 2 files changed, 338 insertions(+), 144 deletions(-) create mode 100644 tests/test_system.py diff --git a/live/node.py b/live/node.py index 4b5e210..53f92dd 100644 --- a/live/node.py +++ b/live/node.py @@ -279,7 +279,7 @@ async def main(): log.info(f" BTC: bid=${btc_bid:,.0f} ask=${btc_ask:,.0f} (spread=${btc_ask-btc_bid:.1f})") log.info(f" ETH: bid=${eth_bid:,.0f} ask=${eth_ask:,.0f} (spread=${eth_ask-eth_bid:.1f})") log.info(f" Mode: POST-ONLY at best bid/ask | Maker: 0.02%") -
