Market order
Fills immediately at the first available price. Fast, but you do not control the price.
Limit order
You set the maximum buy (or minimum sell) price and the order waits until the market reaches it. If it never does, it expires unfilled.
On this platform
- A limit order fills at the market price when that is **better** than your limit.
- Pending orders expire after 5 days.
- While the market is closed, a market order waits for the next session close.
Rule of thumb
Use limits when you expect a dip; use market orders when the decision is urgent.
