What Is Slippage in Trading? Causes, Examples and How to Avoid It

Key Takeaways

Slippage happens when your trade is executed at a different price from the price you expected.

It is most common during high volatility, low liquidity, major news events, market openings, and fast price gaps.

Slippage can be negative or positive. Negative slippage gives you a worse price, while positive slippage gives you a better price.

Market orders are more exposed to slippage because they prioritise execution speed over exact price.

Limit orders can help reduce slippage because they give you more price control, but they may not always be filled.

Stop-loss orders do not always guarantee the exact exit price, especially during sharp market moves or market gaps.

Traders can reduce slippage by trading liquid markets, avoiding major news releases, checking spreads, using the right order types, and managing position size.

Slippage matters more for short-term traders because even a small price difference can affect the result of a trade.

What Is Slippage in Trading?

Slippage in trading is the difference between the price you expect to trade at and the price at which your order is actually executed. It can happen when you open a position or when you close one.

For example, you may place a buy order on a stock CFD at $100, but the trade is filled at $100.20. That $0.20 difference is slippage. If you are trading one unit, the impact may look small. If you are trading 500 units, it becomes much more noticeable.

The basic formula is simple:

Slippage = Actual Execution Price - Expected Execution Price

Slippage is not always bad. If you buy at a lower price than expected or sell at a higher price than expected, that is positive slippage. If you receive a worse price, that is negative slippage. Most traders focus on reducing negative slippage because it increases trading costs and can weaken a trading plan.

It is also important not to confuse slippage with spread or commission. The spread is the difference between the bid and ask price. Commission is a broker fee. Slippage is the price movement that happens between order placement and execution.

Why Does Slippage Happen?

Slippage usually happens because the market moves before your order can be filled at the expected price. This is common in fast-moving markets where prices change in seconds or even milliseconds.

High volatility is one of the biggest causes. During events such as inflation data, central bank decisions, earnings releases, or geopolitical news, prices can move sharply. If you place a market order during that movement, the final execution price may be different from the price shown on your screen.

Low liquidity is another common reason. Liquidity refers to how easily an asset can be bought or sold without causing a major price change. Major forex pairs and large-cap stocks usually have deeper liquidity. Exotic currency pairs, small-cap stocks, some commodities, and certain crypto markets may have thinner liquidity, which can increase slippage.

Order size also matters. A small order may be filled at one price. A larger order may need to be filled across several price levels, especially when there are not enough buyers or sellers at the quoted price.

Execution delay can also play a role. A slow internet connection, platform lag, routing delays, or heavy market activity can increase the time between clicking buy or sell and the order being filled.

When Is Slippage Most Likely to Occur?

Slippage is more likely during major news events. Traders should be especially careful around interest rate decisions, CPI inflation reports, non-farm payrolls, GDP data, company earnings, and major political headlines. These events can cause sudden price jumps and wider spreads.

Market open and market close can also carry higher slippage risk. At the open, markets may react to overnight news or pre-market orders. At the close, liquidity can change as traders adjust or exit positions.

Price gaps are another key risk. A gap happens when the market jumps from one price to another with little or no trading in between. For example, a stock may close at $100 and open the next day at $95 after poor earnings. If you had a stop-loss at $98, it may not execute exactly at $98.

Low-volume sessions can also increase slippage. Holiday trading, overnight sessions, and quieter periods may have fewer market participants, which can make execution less stable.

Slippage Examples in 2026

A simple stock CFD example shows how slippage affects cost. Suppose you want to buy a stock CFD at $300 after a strong earnings report. You place a market order, but because the price is rising quickly, your trade is executed at $300.60. The slippage is $0.60 per unit. If you trade 100 units, the total slippage cost is $60.

In forex, slippage often appears during central bank announcements. A trader may try to enter EUR/USD during an interest rate decision, but the pair moves several pips before the order is filled. If the trade has a tight stop-loss or small profit target, that small price difference can change the whole setup.

Gold is another useful example. Gold prices can react sharply to inflation data, US dollar movement, and rate expectations. If a trader enters a gold CFD position during the first few seconds after a CPI release, the price may move too quickly for the order to fill at the expected level.

Crypto markets can also show strong slippage, especially in less liquid coins or during sudden breakouts. Even though crypto trades around the clock, liquidity is not always equal across all assets and time periods.

How Different Order Types Affect Slippage

Market orders are the most exposed to slippage. They are designed to get you into or out of a trade quickly, but they do not guarantee the exact price. They can be useful in liquid markets, but they are risky during high volatility.

Limit orders give you more price control. When buying, a limit order sets the highest price you are willing to pay. When selling, it sets the lowest price you are willing to accept. The benefit is clear: you avoid a worse price than your limit. The trade-off is that the order may not be filled.

Stop-loss orders help manage risk, but they do not always remove slippage. Once a standard stop-loss is triggered, it may be executed at the next available market price. In a fast-moving market, that price may be worse than your stop level.

Stop-limit orders offer more control because they combine a stop trigger with a limit price. However, they also carry a risk: if the market moves too quickly, your order may not execute.

Guaranteed stop orders, where available, are designed to close a trade at the exact level specified, even if the market gaps. They may involve extra costs and are not available on every market or account type.

How to Avoid Slippage in Trading

The first way to reduce slippage is to use limit orders when price control matters. If you do not want to buy above a certain level or sell below a certain level, a limit order can help you avoid unwanted fills.

Second, avoid using market orders during fast-moving conditions. If a price candle is moving too quickly for you to read clearly, it may not be the best time to send a market order.

Third, trade more liquid markets. Major forex pairs, leading indices, large-cap stocks, and heavily traded commodities usually have better liquidity than niche or thinly traded markets.

Fourth, check the economic calendar before trading. If a high-impact release is due in the next 30 minutes, think carefully before entering a short-term trade. The market may become unstable before and after the announcement.

Fifth, reduce position size in volatile or illiquid markets. A smaller order is usually easier to fill close to the expected price.

Sixth, watch the spread. If the spread suddenly widens, it may be a warning sign that liquidity is falling or volatility is rising.

Seventh, improve your trading setup. Use a stable internet connection, keep your platform updated, and avoid trading from unreliable networks. For algorithmic traders, server speed and execution setup can be even more important.

Finally, choose a broker with strong execution quality. Look for transparent pricing, reliable platforms, clear order policies, and risk-management tools.

How Slippage Affects Trading Performance

Slippage increases trading costs. A small amount of slippage may not seem serious, but it can add up across many trades. If you lose $5 to slippage on 100 trades, that is $500 in hidden execution cost.

It can also change your risk-reward ratio. A worse entry price reduces potential profit. A worse exit price increases loss. If your original trade plan was based on a tight setup, slippage can make the trade less attractive.

Scalpers and day traders are more sensitive to slippage because they often target small price movements. Swing traders may be less affected by tiny slippage, but they still need to watch for weekend gaps and major news events.

Slippage also matters in backtesting. A strategy may look profitable on paper because it assumes perfect entries and exits. In real trading, spreads, slippage, commissions, and order execution all affect results.

FAQs

Conclusion: Slippage Cannot Be Removed, But It Can Be Managed

Slippage is a normal part of trading, but it should not be ignored. It becomes a bigger problem when traders use the wrong order type, trade during major news, enter illiquid markets, or take positions that are too large for the available liquidity.

The goal is not to eliminate slippage completely. The goal is to reduce avoidable slippage and include it in your risk planning. Better order selection, better timing, smaller position sizing, and regular review of execution prices can help you trade with more control.
