Slippage in Forex occurs when the execution price of a trade differs from the expected price. This discrepancy happens due to rapid market movements between the time an order is placed and when it is filled. While often seen as negative, slippage can sometimes be positive, but managing its negative impact is crucial for consistent profitability in the volatile Forex market.
What is Slippage in Forex Trading?
Price slippage in forex is the difference between the price at which you expect your trade to execute and the price at which it actually fills. This discrepancy occurs when market conditions shift between the moment you click “buy” or “sell” and when your broker processes the order—often a matter of milliseconds.
The decentralized nature of the forex market means prices fluctuate constantly across multiple liquidity providers. When your order reaches the market, the originally quoted price may no longer be available, forcing execution at the next best price. This creates slippage.
Understanding Positive vs. Negative Slippage
Slippage isn’t inherently bad—it can work in your favor or against you. Positive slippage occurs when your order fills at a better price than expected: buying at a lower price or selling at a higher price than you requested. Negative slippage happens when you get a worse price: buying higher or selling lower than intended.
According to Investopedia, approximately 70% of retail forex traders experience negative slippage regularly, which directly impacts profitability. While positive slippage does occur, traders tend to notice and remember negative instances more acutely, especially when they erode profits or widen losses.
| Type of Slippage | Expected Price (Buy) | Actual Price (Buy) | Outcome | Pip Difference |
| Positive Slippage | 1.1000 | 1.0995 | Favorable | +5 pips |
| Negative Slippage | 1.1000 | 1.1005 | Unfavorable | -5 pips |
| No Slippage | 1.1000 | 1.1000 | As Expected | 0 pips |
How Slippage Occurs Mechanically?
The slippage process involves three critical moments. First, you see a price on your trading platform and decide to execute. Second, your order travels through your internet connection to your broker’s server. Third, your broker matches your order with available liquidity in the market. Each millisecond of this journey creates opportunity for price movement.
If the market price changes during this execution window—due to high volatility, sudden news, or thin liquidity—your order fills at whatever price is actually available when it reaches the market. Factors like your broker’s execution speed, your internet latency, and the current market depth all determine whether you experience slippage and how severe it becomes.
Why Does Slippage Happen in Forex Trading?
Slippage stems from the fundamental dynamics of how the forex market operates. Understanding these causes helps traders anticipate when slippage is likely and adjust their strategies accordingly. Four primary factors drive slippage: high volatility, low liquidity, significant news events, and technical execution issues.
High Volatility: When Prices Move Too Fast
High volatility creates the perfect environment for slippage. During volatile periods, currency prices can fluctuate multiple times within a single second, making it nearly impossible for brokers to guarantee execution at your requested price. By the time your order reaches the market, the price has already moved—sometimes by several pips.
Major economic announcements like Non-Farm Payroll (NFP) releases or Federal Reserve interest rate decisions trigger explosive volatility. According to FOREX.com, these events are directly correlated with spikes in market volatility and significantly increased slippage risk. A currency pair that normally moves 10-15 pips per hour might suddenly jump 50+ pips in seconds, catching even the fastest execution systems off guard.
The speed of price movement during high volatility overwhelms the normal order matching process. What appears as a stable price on your screen may have already changed by milliseconds before your order arrives. This is why traders often see their orders filled 3-5 pips away from their intended price during volatile sessions, despite having fast internet and a quality broker.
Low Liquidity: Not Enough Market Depth
Liquidity measures how easily you can buy or sell without moving the price. In highly liquid markets like EUR/USD during London hours, millions of dollars trade every minute, creating deep order books with prices stacked closely together. Low liquidity means fewer active buyers and sellers, creating gaps between available price levels.
When you place an order in a low-liquidity environment, your broker may not find enough counter-orders at your requested price to fill your trade completely. The order then gets pushed to the next available price level, which could be several pips away. This is particularly common during the Asian session, late Friday trading, or when trading exotic currency pairs like USD/TRY or EUR/ZAR.
A widening bid-ask spread serves as the primary warning sign of deteriorating liquidity. If EUR/USD normally shows a 0.5-pip spread but suddenly widens to 2-3 pips, liquidity has dried up. Trading during these periods significantly increases your slippage risk, as the market lacks sufficient depth to absorb your order at the displayed price.
Significant News Events: Predictable Unpredictability
Scheduled economic announcements create what traders call “predictable unpredictability.” You know exactly when major news like GDP reports, employment data, or central bank decisions will release, but you cannot predict the market’s reaction or the magnitude of price swings. This creates unique slippage conditions.
During high-impact news events, slippage can exceed 5-10 pips even with reputable brokers, according to EBC.com. Many traders ask, “My broker keeps giving me huge slippage on news events—is this normal?” The answer is yes. Liquidity providers often widen spreads or temporarily step back from the market seconds before major announcements, reducing available liquidity precisely when volatility spikes.
The combination of reduced liquidity and explosive volatility during news creates perfect conditions for severe slippage. A trader placing a market order one second before NFP data releases might see execution 15-20 pips away from their intended price. This isn’t broker manipulation—it reflects genuine market conditions where available prices simply vanish during the chaos of breaking economic data.
Monitoring an economic calendar allows you to anticipate these high-risk windows. Many experienced traders close existing positions before major news or avoid opening new trades within 15-30 minutes of scheduled announcements specifically to sidestep this heightened slippage risk.
Technical Factors: Execution Speed and Latency
Even in normal market conditions, technical factors influence how much slippage you experience. Execution speed refers to how quickly your broker can process and match your order. Brokers with advanced technology infrastructure and direct connections to multiple liquidity providers can execute orders in 10-50 milliseconds, while slower brokers may take 100-300 milliseconds or more.
Latency—the delay in data transmission—compounds this issue. Your order must travel from your device, through your internet connection, to your broker’s server, and finally to the market. Each step introduces delay. A slow internet connection, outdated hardware, or physical distance from your broker’s data center all increase latency, widening the window during which prices can shift.
This is why serious traders use Virtual Private Servers (VPS). A VPS can reduce execution latency by 30-50 milliseconds according to Panda Trading Systems, potentially minimizing slippage, especially for high-frequency strategies. By hosting your trading platform on a server physically located near your broker’s infrastructure, you eliminate much of the internet transmission delay that creates opportunity for slippage.
The trading platform you use also matters. Modern platforms with direct market access and fast order routing experience less slippage than older, slower systems. Your broker’s relationships with liquidity providers and the quality of their technology stack ultimately determine how efficiently they can execute your orders in rapidly moving markets.

Minimizing slippage in Forex involves a multi-faceted approach, combining strategic order placement, optimizing your trading environment, and avoiding high-risk market conditions. Traders can significantly reduce the impact of unexpected price discrepancies by understanding the underlying causes and implementing specific techniques. Proactive measures are key to protecting capital and making sure more predictable trade outcomes.
Using Limit Orders and Pending Orders Strategically
One of the most effective ways to combat negative slippage is by using Limit Orders instead of Market Orders. Limit orders guarantee a specific execution price or better, making sure you only enter or exit a trade at your desired level.
The trade-off is that a limit order may not be filled if the market price never reaches your specified limit. IG states that limit orders guarantee price execution but not fill, while market orders guarantee fill but not a specific price, making them susceptible to slippage.
Pending Orders, which include buy limits, sell limits, buy stops, and sell stops, also offer more control. For instance, a Buy Limit order will only execute at your specified price or lower, preventing negative slippage on entry.
Optimizing Your Trading Environment: Broker, VPS, and Connectivity
Optimizing your trading setup can significantly reduce technical slippage. Choosing a Broker known for its fast Execution Speed and robust infrastructure is paramount. A low-latency connection is essential. Using a Virtual Private Server (VPS) can reduce execution latency by up to 30-50 milliseconds, potentially minimizing slippage, especially for high-frequency strategies, according to Panda Trading Systems.
A VPS makes sure your trading platform is hosted on a high-speed server close to your broker’s servers, minimizing delays. Additionally, a stable and fast internet connection on your end is crucial to reduce personal latency.
Avoiding High-Impact News and Low Liquidity Periods
A straightforward strategy is to simply avoid trading during periods known for high slippage risk. This includes refraining from placing or closing trades immediately before, during, and after Significant News Events. Similarly, avoid trading during times of low liquidity, such as late Friday sessions or during major holidays when market participation is thin.
Regularly consulting an Economic Calendar allows traders to anticipate these periods of heightened volatility and plan their trades accordingly.
Understanding Stop Loss vs. Slippage
Many traders ask, “Does slippage affect stop loss?” Yes, slippage can significantly impact your Stop Loss orders. A stop loss is typically a market order, meaning it aims to close your position at the best available price once a certain threshold is breached.
If the market gaps past your stop loss level due to high volatility or low liquidity, your trade will be closed at the next available price, which could be significantly worse than your intended stop loss. This is often the reason a stop loss is “hit way past my set price.”
Some brokers offer “guaranteed stop losses” for an additional fee, which make sure execution at the exact specified price, regardless of market conditions.
Broker Comparison: Factors Influencing Slippage
Choosing the right Broker is a critical step in minimizing slippage. Different brokers offer varying Execution Speed, liquidity providers, and order handling policies, all of which impact how frequently and severely you experience slippage. Traders often wonder, “What’s the best way to test a broker’s slippage?”
The best approach involves using a demo account under live market conditions, analyzing historical execution reports, and comparing results across different brokers during similar market events. Look for brokers that are transparent about their execution policies and offer competitive spreads.
| Factor | Description | Impact on Slippage |
| Execution Speed | Time taken to process orders | Faster speed reduces slippage |
| Liquidity Providers | Number and quality of providers | More providers reduce slippage |
| Requotes | Broker offers new price | Indicates poor execution/liquidity |
| Order Types | Availability of limit/guaranteed stops | Offers control over execution price |
| Average Spread | Cost of trading | Wider spreads increase total cost |
Is slippage common in forex?
Yes, a small amount of slippage is common in forex trading, especially during normal market hours and periods of moderate volatility. The Forex Market is constantly moving, and minor discrepancies between expected and actual prices are a regular occurrence due to the sheer volume and speed of transactions.
It is a fundamental characteristic of trading in a dynamic, decentralized market.
What is the difference between slippage and spread?
The difference between slippage and Bid-Ask Spread is crucial for understanding trading costs. The bid-ask spread is the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask). It is a fixed, explicit cost of trading.
Slippage, however, is an unexpected, variable cost that occurs when an order is filled at a price different from the one displayed or requested due to market shifts. While spread is always present, slippage only occurs under specific market conditions.
How Much Slippage is ‘Normal’ or Acceptable?
The amount of slippage considered ‘normal’ or acceptable varies depending on market conditions and the currency pair. In typical market conditions, 0. 5-2 pips of slippage might be considered acceptable, particularly during moderate volatility. However, during high-impact News Events or periods of extreme low liquidity, slippage of 5 pips or more, as EBC.
com observed, can occur. Traders should be concerned when they consistently experience significant negative slippage (e. g. , more than 3-5 pips) in normal market conditions, as this could indicate issues with their broker’s execution or their own trading strategy.

Open a Free Demo AccountBeyond Mechanics: The Psychological Impact of Slippage
Unexpected negative slippage can lead to frustration, revenge trading, and loss of confidence, significantly impacting long-term trading performance. Unlike most guides that only focus on the mechanics, we delve into the often-overlooked Psychological Impact of Slippage and how to manage it.
The feeling of a Stop Loss being hit significantly past the set price, especially during News Events, can trigger strong emotions. According to Investopedia, approximately 70% of retail forex traders experience negative slippage regularly, reinforcing feelings of being “cheated” or losing control.
This emotional toll can lead to impulsive decisions, such as increasing position sizes to “get back” losses (revenge trading) or abandoning a well-tested strategy due to perceived unfairness. To manage these emotions, traders should accept slippage as an inherent, albeit sometimes frustrating, cost of trading in the Forex Market.
Developing mental resilience involves acknowledging that not every trade will execute perfectly and focusing on long-term probabilities rather than individual outcomes. Implement strict risk management rules and stick to them, regardless of short-term market anomalies.
