What Is a Limit Order? (Day Trading Glossary)

A limit order is an instruction to buy or sell a stock at a specific price or better. You set the price you're willing to accept, and the trade only happens if the market meets it.

You trade the guarantee of getting filled for control over the price you get.

Buy limit and sell limit

There are two sides to it.

A buy limit order sets the most you'll pay. If you place a buy limit at $10, the order fills at $10 or lower, never higher. It's a way to avoid chasing a stock up.

A sell limit order sets the least you'll accept. If you place a sell limit at $12, the order fills at $12 or higher, never lower. You use it to lock in a target price on the way out.

The trade-off

A limit order gives you price control, and that control has a cost. If the stock never trades at your price, your order simply doesn't fill, and you can miss the move entirely. You can also get a partial fill, where only some of your shares go through because there weren't enough available at your price.

So a limit order answers "what price," but it can't promise "will it happen."

Limit order vs market order

The other common order type is a market order, and it's the opposite trade-off. A market order fills right away at the best available price, so you're almost certain to get in, but you don't control the exact price you pay. A limit order controls your price but might not fill.

How I use limit orders

For the fast small-caps I trade, this choice actually matters, because the spread between the buy and sell price can be wide. I use a limit order to control what I pay so I don't get a terrible fill on a thin, jumpy stock. If I want in around $1.78, I can cap what I'm willing to pay instead of hitting the market and overpaying by several cents.

There's a catch I stay honest about. On a stock that's moving fast, a limit set too tight can leave me behind while the move runs without me. So I'm always weighing two things: getting filled, and not overpaying. On a wide-spread low-float runner, price control is worth more. On a clean fast break, getting in matters more. That judgment, along with a pre-planned stop, is part of how I trade.

Frequently asked questions

What are the downsides of a limit order?

The main one is that it might not fill. If the stock never reaches your price, you're left out of the trade, which can mean missing a move you wanted. You can also get only a partial fill. A limit order protects your price, but it can cost you the trade itself.

Should I use a market order or a limit order?

It depends on what matters more for that trade. Use a market order when getting filled quickly is the priority and the stock is liquid enough that the price won't move much against you. Use a limit order when you want to control your price, especially on a thin stock with a wide spread. Many traders use limit orders as their default for exactly that reason.

What is the difference between a limit order and a stop order?

A limit order works right away at the price you set. A stop order sits inactive until the stock hits a trigger price, and only then does it turn into a live order. A stop is often used to get out, while a plain limit is used to get in or out at a chosen price.
