From 27eb5d4fe87e49f4950da8970fbf84b376e5000d Mon Sep 17 00:00:00 2001 From: mindesbunister Date: Fri, 14 Nov 2025 09:50:13 +0100 Subject: [PATCH] fix: Critical rate limit handling + startup position restoration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Problem 1: Rate Limit Cascade** - Position Manager tried to close repeatedly, overwhelming Helius RPC (10 req/s limit) - Base retry delay was too aggressive (2s → 4s → 8s) - No graceful handling when 429 errors occur **Problem 2: Orphaned Positions After Restart** - Container restarts lost Position Manager state - Positions marked 'closed' in DB but still open on Drift (failed close transactions) - No cross-validation between database and actual Drift positions **Solutions Implemented:** 1. **Increased retry delays (orders.ts)**: - Base delay: 2s → 5s (progression now 5s → 10s → 20s) - Reduces RPC pressure during rate limit situations - Gives Helius time to recover between retries - Documented Helius limits: 100 req/s burst, 10 req/s sustained (free tier) 2. **Startup position validation (init-position-manager.ts)**: - Cross-checks last 24h of 'closed' trades against actual Drift positions - If DB says closed but Drift shows open → reopens in DB to restore tracking - Prevents unmonitored positions from existing after container restarts - Logs detailed mismatch info for debugging 3. **Rate limit-aware exit handling (position-manager.ts)**: - Detects 429 errors during position close - Keeps trade in monitoring instead of removing it - Natural retry on next price update (vs aggressive 2s loop) - Prevents marking position as closed when transaction actually failed **Impact:** - Eliminates orphaned positions after restarts - Reduces RPC pressure by 2.5x (5s vs 2s base delay) - Graceful degradation under rate limits - Position Manager continues monitoring even during temporary RPC issues **Testing needed:** - Monitor next container restart to verify position restoration works - Check rate limit analytics after next close attempt - Verify no more phantom 'closed' positions when Drift shows open --- lib/drift/orders.ts | 8 +- lib/startup/init-position-manager.ts | 121 ++++++++++++++++----------- lib/trading/position-manager.ts | 16 +++- 3 files changed, 95 insertions(+), 50 deletions(-) diff --git a/lib/drift/orders.ts b/lib/drift/orders.ts index 1fae51e..a100ad6 100644 --- a/lib/drift/orders.ts +++ b/lib/drift/orders.ts @@ -644,11 +644,17 @@ export async function closePosition( */ /** * Retry a function with exponential backoff for rate limit errors + * + * Helius RPC limits (free tier): + * -
