Key takeaways
Market orders fill now at any price. Limit orders fill at your price or better, or not at all. Stop orders become market orders when triggered; stop-limits become limit orders and can be skipped. Brackets attach a stop and a target to every entry. Slippage is measured in ticks, and ticks are dollars.
Every futures trade starts and ends with an order. The type of order you use decides two things: whether you get filled, and at what price. Choosing the wrong one can cost you ticks on every trade or leave you without protection when the market moves fast. This lesson covers the orders you will use every day and shows what each choice costs in dollars.
Key points
- Market orders fill immediately at the best available price, with no price guarantee.
- Limit orders fill only at your price or better, with no fill guarantee.
- Stop orders turn into market orders when the stop price trades. They are the standard way to cap a loss.
- Stop-limit orders turn into limit orders when triggered and can be skipped in a fast move.
- Bracket (OCO) orders attach a stop-loss and a profit target to your entry; when one fills, the other cancels.
- Slippage is the gap between the price you expected and the price you got. Multiply it by tick value to see the cost.
Bid, ask and the order book
At any moment there is a highest price someone will pay (the bid) and a lowest price someone will sell at (the ask or offer). On a liquid contract like ES, the bid and ask are usually one tick apart. A buy at market fills at the ask; a sell at market fills at the bid. Resting limit orders build the order book that market orders trade against.
Market order
A market order fills immediately at the best available price. You get certainty of execution but not of price. In normal conditions on ES or MES, you usually fill at the current ask or bid. In fast markets, such as just after a major economic release, the book can thin out and you can be filled several ticks away. That difference is called slippage.
Worked example: what slippage costs
MES shows 6,000.00 bid and 6,000.25 ask. You send a market buy for 4 MES during a news spike and are filled at 6,001.00, three ticks above the ask you saw. Slippage cost: 3 ticks × $1.25 × 4 contracts = $15. The same three ticks on 4 ES would be 3 × $12.50 × 4 = $150.
Limit order
A limit order fills only at your price or better. A buy limit sits below the current market; a sell limit sits above it. You control price, but you may not get filled at all if the market never trades at your level, or trades there only briefly and your order is behind others in the queue.
Worked example: limit entry
MNQ is trading at 21,020.00. You place a buy limit at 21,000.00. If price drops to 21,000.00 and enough volume trades there, you are filled at 21,000.00 or better. If price turns at 21,000.50, you miss the trade completely. Profit targets are usually limit orders, since you want a specific price or better.
Stop order
A stop order rests away from the market and becomes a market order once price trades at your stop level. Traders use sell stops below a long position (and buy stops above a short) to cap losses. Stops can also be used to enter a breakout: a buy stop above resistance enters only if price rises through it.
Worked example: stop-loss risk
You buy 1 MES at 6,000.00 and place a sell stop at 5,990.00. That is 10 points, or 40 ticks. Planned risk: 40 × $1.25 = $50. If the stop triggers in a fast market and fills two ticks lower at 5,989.50, the actual loss is 42 ticks, or $52.50. Plan for some slippage on stops, especially around news.
Stop-limit order
A stop-limit becomes a limit order, not a market order, when triggered. It controls the fill price but can be skipped. If you use a sell stop at 5,990.00 with a limit at 5,989.00 and price gaps from 5,991.00 straight to 5,987.00, your order may sit unfilled while the loss grows. For protective stops, most traders accept the slippage risk of a plain stop rather than the risk of no fill.
Bracket (OCO) orders
A bracket attaches a stop-loss and a profit target to your entry. When one exit fills, the other is cancelled automatically ("one cancels other"). Most futures platforms support brackets, including those offered by brokers such as NinjaTrader and Tradovate. Brackets are the simplest way to make sure every trade has a defined exit before emotions get involved.
Worked example: a 1:2 bracket
You buy 2 MES at 6,000.00 with a bracket: stop at 5,990.00 and target at 6,020.00.
- Risk: 10 points × $5 × 2 = $100
- Reward: 20 points × $5 × 2 = $200
- Risk-to-reward ratio: 1:2
If the target fills, the stop is cancelled. If the stop fills, the target is cancelled. Check ratios like this with the risk-reward calculator.
Trailing stop
A trailing stop moves with the market in your favor by a set distance and never moves back. Long 1 MNQ at 21,000 with a 20-point trail: if price rises to 21,050, the stop rises to 21,030, locking in 30 points ($60). If price then falls, the stop stays at 21,030. Trailing stops let winners run but can be triggered by normal pullbacks if set too tight.
Time in force
- Day: the order is cancelled at the end of the trading session if not filled.
- GTC (good till cancelled): the order stays active until filled or you cancel it. Brokers may cancel GTC orders at contract expiry.
Check how your platform handles orders across the daily maintenance break and at the weekly close.
Practical tips
- Place your stop at a level that proves your trade idea wrong, then size the position so a stop-out costs only what you planned to risk.
- Avoid market orders in thin markets, such as late at night on less active contracts, or in the seconds after a major release.
- Never leave a position without a stop in the market. Mental stops are easy to ignore.
- Practice order entry on a simulator first. Clicking the wrong button with real money is an expensive mistake.

Frequently asked questions
Which order type is best for beginners?
A limit or market entry with a bracket attached. The bracket makes sure a stop and a target are in place from the moment you enter.
Why did my stop fill worse than my stop price?
A stop becomes a market order once triggered. If the market moves quickly, the next available price can be several ticks away. That difference is slippage.
Is a stop-limit safer than a stop?
It protects your price but not your exit. In a fast move, a stop-limit can be skipped and leave you in a losing position.
Does a limit order guarantee a fill if price touches my level?
No. Orders at the same price fill in queue order. If price touches your level only briefly, orders ahead of yours may use up the available volume.
Do prop firms allow all order types?
Most evaluation platforms support market, limit, stop and bracket orders. Check your firm's rules and platform guide for any restrictions.
