Best Practices

  • Small Orders: Execute faster with less market impact
  • Large Orders: Consider breaking into smaller chunks
  • Iceberg Orders: Hide large order sizes from the market
  • Limit Orders: Set competitive prices for better fill rates
  • Market Orders: Use for immediate execution, accept slippage
  • Stop Orders: Set appropriate buffer from current price
  • Always set stop losses for positions
  • Use position sizing appropriate for your risk tolerance
  • Monitor order status and market conditions
