A limit order is an instruction to buy or sell a futures contract at a specific price or better—unlike a market order, it will only execute if the market reaches your specified price. You're in control. The market has to come to you.
That single distinction changes everything about how you manage entries, exits, and risk in futures trading.
How a limit order works
When you place a limit order, you're setting a price boundary. The order sits in the market, queued in the exchange's order book at venues like CME Group, until the market price either hits or surpasses your level. If it never gets there, the order doesn't fill.
Buy limit orders explained
A buy limit order is placed below the current market price. You're saying: "I want in, but only if price drops to this level." If the market trades down to your limit price or lower, your order fills. If price rallies away from your level without touching it, you stay flat.
Sell limit orders explained
A sell limit order works the mirror image: It's placed above the current market price. You're targeting a level where you'd be happy to sell, either to initiate a short position or exit a long position at your profit target.
How limit orders are filled
When using a limit order to buy, the order fills at your limit price or lower; when selling, it fills at your limit price or higher—guaranteeing price but not execution.
That last part matters. When your limit price is reached, your order joins the queue at that price level in the order book. On most popular futures contracts, orders are matched on a price-time priority basis—first in line at a given price gets filled first. In fast markets, your order could be reached but not fully filled if liquidity at that level runs out.

Limit order vs. market order: What's the difference?
The core tradeoff is simple: price certainty vs. fill certainty.
| Limit order | Market order | Stop order | |
|---|---|---|---|
| Price control | Yes; fills at your price or better | No; fills at current market price | Partial; converts to market when triggered |
| Fill guarantee | Not guaranteed | Virtually guaranteed | Not guaranteed after trigger |
| Best use case | Entries at specific levels, take-profits | Urgent entries/exits, fast-moving markets | Stop-losses, breakout entries |
| Slippage risk | None (by design) | Higher in volatile markets | High in volatile markets; can slip after trigger |
If you need to be in a trade right now, a market order gets it done. If you need to be in at a specific price, a limit order is your tool. For a full breakdown of order types, check out our guide to the basic order types explained.
When to use a limit order in futures trading
Limit orders are commonly used in futures trading to target specific entry points, lock in take-profit levels, or avoid unfavorable fills during fast-moving markets. Like any specialized tool, they're only as good as the plan behind them.
Using limit orders for entries
Limit orders shine when you've identified a specific price level you want to trade from—a support zone, a retracement level, a previous high or low. Rather than chasing price after a move, you set your order and let the market do the work.
This can be especially valuable in futures markets, where spreads can widen and price can gap. Placing a limit order gives you price discipline baked right into the execution.
Using limit orders for exits and take-profits
Take-profit targets are one of the most common uses of sell limit orders. Once you're in a trade, you can post your target in advance and walk away. If price reaches your level, you're out at your intended profit. No second-guessing. No watching the screen all day.
This approach also helps remove emotion from the equation—which, for some traders, is where real edge gets lost.
Limit orders and price slippage
Slippage is the difference between the price you expected and the price you received. It's a real cost in active markets, and it's one of the reasons limit orders are so valuable.
Because a limit order will only fill at your specified price or better, slippage is effectively zero on the entry side. You won't get filled at a worse price than you set. The tradeoff is that you might not get filled at all if the market doesn't reach your level.
Compare that to a market order during a volatile move—your fill could be several ticks worse than where price appeared when you clicked. In liquid futures markets, slippage tends to be a tick or two; in fast-moving, thin conditions, it can cost you the trade.

Common mistakes traders make with limit orders
Limit orders are precise by design—until they're not. Here are some of the common ways traders misuse them, and what to do instead.
Setting and forgetting without a plan
A limit order sitting open overnight in a news-heavy market can fill at your price—right into a gap move against you. Always know what working orders you have before stepping away.
Placing limits too far from market
If your buy limit is 20 ticks below a fast market, it may never fill. Price discovery is quick in liquid futures; don't set levels so conservative that you miss the trade entirely.
Ignoring time-in-force settings
NinjaTrader lets you set limit orders as day (expires at session close) or GTC (good 'til canceled). Forgetting to check this can leave stale orders live longer than intended.
Confusing limit orders with stop-limit orders
A stop-limit order combines a stop trigger with a limit price and is useful for breakout entries with price control. They're related but distinct tools. Know which one you're using.
The mistakes above share a root cause: placing an order without fully understanding what happens after it fills. Limit orders are low-maintenance by design, but they're not zero-maintenance.
The bottom line on limit orders
Limit orders don't guarantee you'll get into every trade. What they guarantee is that when you do, it's on your terms.
Price discipline separates reactive traders from intentional ones. A limit order is how you put that discipline into action—whether you're stalking a specific entry level, locking in a take-profit, or simply refusing to chase a move that's already run.
The mechanics are straightforward. The application takes practice. And like most things in trading, the real edge comes from consistency: using the right tool for the right situation, at the right time.
NinjaTrader gives you the infrastructure to execute with precision—from the SuperDOM to Chart Trader to a full simulated trading environment where you can build these habits before you put real capital on the line.

No. A limit order guarantees the price you'll receive if filled, but not that the order will be filled at all. The market must trade at or through your limit price, and there must be sufficient liquidity at that level to match your order.
If the market never hits your limit price, the order remains open (working) until it's either canceled manually or expires based on your time-in-force setting. No fill, no trade.
Absolutely—and it's one of the best uses for them. A sell limit order placed above your entry locks in a profit target automatically. When price reaches your level, the order fills and you're out at your intended profit without needing to monitor the position in real time.
A limit order is passive; it rests in the order book waiting for price to come to it. A stop order is triggered when price reaches a specific level, at which point it typically converts to a market order. Stop orders are most commonly used for stop-losses or breakout entries.
