Limit order

An instruction to buy or sell only at a stated price or better. It joins the order book and waits, and may never execute.

Example

A limit to buy at 47.85 rests in the book until a seller is willing to meet it.

Important

The risk is not filling; the risk of the alternative is filling at whatever the queue contained. For a long-horizon buyer, missing by two cents costs less than slipping thirty.

Lessons that explain it

  • A continuous auction: what the quote is, and what it is not — The price is what the marginal buyer and the marginal seller agreed a moment ago. It is a fact about two people, and it is not a valuation. (12 min)
