  2. Keep some USD buffer - Avoid failed trades due to insufficient funds

  3. Use limit orders for FX - Save a few dollars on conversion

  4. Check trade confirmations - Ensure recurring buys are executing

  5. Reinvest dividends manually - IBKR doesn't auto-reinvest dividends

  6. Annual rebalancing - Adjust allocations once a year if needed

Set it up once, and let your money grow automatically. The best investment strategy is the one you can stick to - and automation makes that easy!
