CATASTROPHIC BUG DISCOVERY (Nov 14, 2025):
- Helius free tier (10 req/sec) was the ROOT CAUSE of all Position Manager failures
- Switched to Alchemy (300M compute units/month) = INSTANT FIX
- System went from completely broken to perfectly functional in one change
Evidence:
BEFORE (Helius):
- 239 rate limit errors in 10 minutes
- Trades hit SL immediately after opening
- Duplicate close attempts
- Position Manager lost tracking
- Database save failures
- TP1/TP2 never triggered correctly
AFTER (Alchemy) - FIRST TRADE:
- ZERO rate limit errors
- Clean execution with 2s delays
- TP1 hit correctly at +0.4%
- 70% closed automatically
- Runner activated with trailing stop
- Position Manager tracking perfectly
- Currently up +0.77% on runner
Changes:
- Added CRITICAL RPC section to Architecture Overview
- Made RPC provider Common Pitfall #1 (most important)
- Documented symptoms, root cause, fix, and evidence
- Marked Nov 14, 2025 as the day EVERYTHING started working
This was the missing piece that caused weeks of debugging.
