You click buy on the ES at 4100. The confirmation came back at 4105, and you ended up paying five extra points on a trade you thought was locked in. That gap between the price you expected and the price you got is slippage, and it shapes the outcome of almost every futures trade, whether you notice it or not.
So what actually causes it, and what can you do about it? We will start with the basics: what slippage is and why futures traders feel it more than most. From there, we cover the causes, how different order types change your exposure, and the fixes that actually move the needle. Because a slipped stop hits differently on a funded account, we close with what that means for your drawdown limit.

What Is Slippage in Futures?
A lot of futures traders learn about slippage the hard way, before they even know the term: you place an order at one price, and the fill lands somewhere else. That gap is slippage.
It is a normal cost of trading fast, liquid markets, not a platform glitch or a broker mistake. Nobody charges you for it directly, either. It happens because the market keeps moving in the brief window between your click and the exchange completing your order.
Positive vs negative slippage
It is also not automatically bad. Fill at a better price than expected, and that is positive slippage. Fill worse, and it is negative, which is the version most traders actually notice, since it shows up as an unplanned cost.
Futures add another wrinkle: leverage magnifies every tick, so slippage bites harder here than it would on a stock trade. One mistimed market order on a volatile day can shove your fill several ticks the wrong way.
Why slippage matters more in futures
Scalpers feel slippage the most, since a few ticks can wipe out a big chunk of a tight target.
That does not mean it skips everyone else, though. A swing trader holding a bigger position can lose just as much dollar value from a single bad fill. It is not really a scalper’s problem specifically.
It is a cost every futures trader needs to plan around, regardless of style or timeframe.

Positive vs Negative Slippage
| Type | What Happens | Effect on You |
|---|---|---|
| Positive slippage | You fill at a better price than expected | A small, unplanned gain |
| Negative slippage | You fill at a worse price than expected | A higher cost or a bigger loss |
| No slippage | You fill at your expected price | Common in calm, liquid markets |
What Causes Slippage in Futures?
Slippage rarely comes from one thing. Volatility is usually the loudest culprit, since a news release or a sudden order imbalance can move price several ticks in a second. Low liquidity makes it worse because too few buyers or sellers are waiting at your price.
Order size adds another layer: a large order often cannot be filled entirely at one price, so part of it slips. Execution speed matters too, since any delay in reaching the exchange gives the market more time to move against you.
Slippage vs the bid-ask spread
Slippage and the bid-ask spread get confused a lot, but they are measuring different things. The spread is the standing gap between the best buy and sell prices at any given moment.
Slippage is how far your actual fill lands from the price you expected when you clicked. A wide spread can contribute to slippage, particularly on market orders, though the two are not the same concept.
That distinction is worth remembering, because slippage is not the broker cheating you. It is a mechanical byproduct of speed and liquidity, not a hidden fee or some rigged outcome.

When Slippage in Futures is Worst
High volatility is when slippage tends to get worse, especially around major news releases and in thin, low-volume contracts. Trading outside peak hours widens it too, since fewer participants are active in the book. Exchanges do build in some protection here.
CME’s Velocity Logic, for example, can briefly pause or slow a market during an especially sharp, fast move. That safeguard will not eliminate slippage, but it can soften the most extreme swings.
Thin contracts carry the most slippage overall, while liquid contracts like the E-mini S&P 500 usually see far less.

What Causes Slippage
| Cause | Why It Happens | When It Bites |
|---|---|---|
| Volatility | Price moves fast between order and fill | News releases, sharp moves |
| Low liquidity | Too few buyers and sellers at your price | Thin contracts, off-hours |
| Order size | Large orders cannot be filled at a single price | Multi-contract entries |
| Execution speed | Latency delays your order reaching the book | Slow connections |
Order Types and Slippage
The order type you choose decides how much slippage risk you take on. A market order guarantees you get filled, but not at any specific price, since it simply takes the next available level.
A limit order works the opposite way: it guarantees your price or better, but it may never fill if the market runs away from you.
Because of that trade-off, many traders use limit orders for entries where timing is flexible. They save market orders for exits, where getting out matters more than the exact price.
Market orders vs limit orders
Stop-loss orders deserve special attention, since they can slip in ways traders do not always expect. Most stop-losses act as market orders once triggered, which means a fast move can fill your stop worse than the level you set.
A limit order does not fully solve this either, since it guarantees your price, not your fill. That means it can protect you from slippage while leaving you out of the trade entirely if the price never returns to your level.
Slippage can happen on both entries and exits, which is why many traders mix order types depending on the situation.
đź”—Order Types
A worked example on the ES
Consider a real example on the ES. You see 4100 on your screen and send a market order to buy. By the time the order actually reaches the exchange, the best price has already moved. Your fill comes back at 4105, five points worse, and nobody planned for that. A market order in a calm, liquid session might fill close to the displayed price, but it offers no real protection once conditions turn fast. That is the trade-off traders make every time they choose speed over price certainty.
Order Types and Slippage
| Order Type | Guarantees Price? | Guarantees Fill? | Slippage Risk |
|---|---|---|---|
| Market | No | Yes | High, takes the next available price |
| Limit | Yes | No | None if filled, but may fill at all |
| Stop (stop-market) | No | Yes, once triggered | High becomes a market order |
| Stop-limit | Yes | No | Lower, but may miss a fast move entirely |
How to Reduce and Measure Slippage in Futures
You cannot eliminate slippage completely, since it is a normal feature of live, fast-moving markets. What you can do is shrink most of it through better order types, timing, and contract choice. That comes down to a handful of habits, not a single trick, and most of them are things you already control on every trade you place.
Practical ways to reduce slippage
Limit orders on entries protect your price, though you will occasionally miss a fill because of it. Trading during peak liquidity hours, like the U.S. cash open, tends to tighten spreads and improve execution.
đź”—Trading Hours
Avoiding market orders right around major news releases helps too, since that is when conditions turn thinnest and fastest. Cutting execution latency matters as well, since a faster, more stable connection or a VPS reduces the delay that causes late, slipped fills.
đź”—Trading VPS
The maximum deviation setting is another useful tool where your platform supports it. On MT4 and MT5, it lets you cap how many ticks you will accept away from your requested price.
If the fill would land outside that range, the order simply cancels instead of filling at a worse level. Not every futures platform offers this control in the same form, so check what your specific broker or prop firm provides.
How to measure your slippage
Measuring your own slippage matters just as much as trying to reduce it. Compare your expected entry or exit price to your actual fill on every trade, and log the difference.
Track that gap in ticks or dollars across enough trades, and real patterns start to show. A backtest with perfect fills can look great on paper and still fall apart once live slippage gets added in.
A realistic slippage buffer in your testing and risk model keeps expectations grounded before real capital is on the line.
Ways to Reduce Slippage
| Tactic | How It Helps | Trade-Off |
|---|---|---|
| Use limit orders | Fills only at your price or better | May miss the trade |
| Trade peak hours | More liquidity, tighter fills | Fewer setups off-hours |
| Avoid major news | Skips the fastest, thinnest moments | May sit out a big move |
| Trade liquid contracts | Deeper order book, less slip | Fewer niche markets available |
| Cut latency (VPS) | Faster order reaches the book | Setup effort and added cost |
The Slippage-Control Checklist
- Use limit orders for entries whenever timing allows
- Trade liquid contracts during peak hours like the U.S. open
- Avoid firing market orders straight into major news releases
- Set a maximum deviation cap where your platform allows it
- Build a slippage buffer into your backtests and risk plan
- Cut latency with a stable connection or a VPS
Slippage on a Funded Account
On a funded futures account, slippage stops being a minor annoyance and starts being a real risk to your rules. The reason comes down to how drawdown limits work.
The5ers Futures, for example, uses a 3% end-of-day max loss on both evaluation and funded accounts, calculated once at the close of the session rather than tick by tick during the day.
That structure gives you more room to absorb an intraday swing than a live trailing drawdown would. It does not remove the risk that a slipped stop adds to your day’s total loss.
đź”—Drawdown Rules
How a slipped stop threatens your drawdown limit
Picture a trade where you plan to risk $100 with a tight stop-loss below your entry. In a fast move, that stop can fill worse than the level you set, since it typically becomes a market order once triggered. Instead of losing the planned $100, you close out $120 down.
That extra $20 was never part of the plan, and repeated across a few trades in one session, differences like that add up fast. Because The5ers Futures measure loss at the end of the day, those extra dollars still count toward the 3% limit before the session closes.
Protecting a funded account from slippage
Slippage does not fail a challenge or a funded account on its own, and it is not something to fear outright. However, a slipped stop can push a loss past your daily total and closer to your limit.
Protecting against that starts with the habits covered throughout this guide: realistic stop placement, avoiding market orders into major news, and sizing positions so one bad fill cannot threaten the account.
On The5ers Futures specifically, that discipline matters even more, given the firm’s per-position consistency rule and its fixed contract caps during the evaluation stage.
đź”—Consistency Rule
 How Slippage Threatens a Funded Account
| Scenario | What Happens | Why It Matters |
|---|---|---|
| Planned stop loss | You expect to lose $100 | Your risk plan assumes an exact fill |
| Stop slips in a fast move | You actually lose $120 | The extra $20 was never in the plan |
| Slippage repeats across trades | Small differences add up over a session | The account drifts closer to its loss limit |
| Loss nears the 3% end-of-day cap | The account can close out at day’s end | The end-of-day max loss is a hard rule |
Slippage Is Normal, but It Is Yours to Manage
Slippage is a normal part of trading fast, leveraged futures markets, and it is not a sign that something is broken. Your order type, your timing, and your contract choice all shape how much of it you feel.
Most of it, in other words, comes down to decisions you already make. Treat it as a cost you manage rather than a mystery, and your results hold up better over time.
The causes are not complicated once you know what to look for: volatility, thin liquidity, order size, and execution speed. Limit orders and peak-hour timing keep fills tighter.
Avoiding major news cuts out some of the worst moments, and cutting latency through a stable connection or a VPS closes the remaining gap. Ignoring slippage, in contrast, lets it quietly erode an edge that otherwise looks solid on paper. On a funded account, that discipline carries even more weight, since your drawdown limit does not bend for a bad fill.
Planning for slippage before your next trade protects both your results and your rule compliance. If you are ready to trade with that kind of discipline on a funded futures account, explore the The5ers Futures evaluation program and see how the rules apply to your own strategy
