- Memory leak identified: Drift SDK accumulates WebSocket subscriptions over time
- Root cause: accountUnsubscribe errors pile up when connections close/reconnect
- Symptom: Heap grows to 4GB+ after 10+ hours, eventual OOM crash
- Solution: Automatic reconnection every 4 hours to clear subscriptions
Changes:
- lib/drift/client.ts: Add reconnectTimer and scheduleReconnection()
- lib/drift/client.ts: Implement private reconnect() method
- lib/drift/client.ts: Clear timer in disconnect()
- app/api/drift/reconnect/route.ts: Manual reconnection endpoint (POST)
- app/api/drift/reconnect/route.ts: Reconnection status endpoint (GET)
Impact:
- Prevents JavaScript heap out of memory crashes
- Telegram bot timeouts resolved (was failing due to unresponsive bot)
- System will auto-heal every 4 hours instead of requiring manual restart
- Emergency manual reconnect available via API if needed
Tested: Container restarted successfully, no more WebSocket accumulation expected
- Add SymbolSettings interface with enabled/positionSize/leverage fields
- Implement per-symbol ENV variables (SOLANA_*, ETHEREUM_*)
- Add SOL and ETH sections to settings UI with enable/disable toggles
- Add symbol-specific test buttons (SOL LONG/SHORT, ETH LONG/SHORT)
- Update execute and test endpoints to check symbol enabled status
- Add real-time risk/reward calculator per symbol
- Rename 'Position Sizing' to 'Global Fallback' for clarity
- Fix position manager P&L calculation for externally closed positions
- Fix zero P&L bug affecting 12 historical trades
- Add SQL scripts for recalculating historical P&L data
- Move archive TypeScript files to .archive to fix build
Defaults:
- SOL: 10 base × 10x leverage = 100 notional (profit trading)
- ETH: base × 1x leverage = notional (data collection)
- Global: 10 × 10x for BTC and other symbols
Configuration priority: Per-symbol ENV > Market config > Global ENV > Defaults
