Basic Order Types
The three core order types every trader should know:
- Market order: Executes immediately at the best available price. Guarantees fill but not price; use when speed matters more than exact price.
- Limit order: Executes only at your specified price or better. Guarantees price but not fill; use when you want control over entry or exit price.
- Stop order: Triggers when price reaches a level, then executes as market (or limit with stop-limit). Used for stop losses and breakout entries.
Advanced Order Types
Many platforms offer advanced orders to automate your plan:
Bracket orders
Combine entry with profit target and stop loss in one order. Useful for disciplined take-profit and stop-loss without manual management.
Trailing stop
Stop level moves with price to lock in profits while giving the trade room to run. Helps capture trends without giving back gains.
Execution Best Practices
Improve execution quality with these habits:
- Use limit orders when you can to control price and reduce slippage.
- Avoid large market orders in thin or fast markets; split size or use time-weighted execution.
- Monitor costs (commission and spread) as a percentage of your edge; minimize trading when costs are high.
Frequently Asked Questions
When should I use a market order vs a limit order?
Use market orders when you need to get in or out immediately (e.g., closing a position on news). Use limit orders when you have a specific price in mind and can wait for the fill. For stop losses, decide whether you prefer guaranteed exit (stop-market) or price control (stop-limit), knowing stop-limit may not fill in a gap.
What is slippage and how can I reduce it?
Slippage is the difference between your expected fill price and the actual fill. To reduce it: use limit orders where possible, trade in liquid sessions, avoid trading through major news, and break large orders into smaller chunks.
