Slippage is a common phenomenon in financial markets that every trader—whether novice or experienced—must understand. It refers to the difference between the expected price of a trade and the actual price at which the trade is executed. This discrepancy can occur in any market, including stocks, forex, commodities, and cryptocurrencies, especially during periods of high volatility or low liquidity.
While slippage is often seen as a negative occurrence, it can sometimes work in a trader’s favor, resulting in a better-than-expected execution price—known as positive slippage. However, more frequently, traders face negative slippage, where they pay more (or receive less) than anticipated. Understanding the causes, implications, and mitigation strategies for slippage is essential for effective trading.
What Is Slippage?
Slippage occurs when a trade order is filled at a price different from the one expected at the time of placement. This difference arises due to market dynamics such as volatility, order size, and liquidity.
In practical terms, if you place a market order to buy 100 shares of a stock at $50 per share, but the order executes at $50.10 due to rapid price movement, you’ve experienced negative slippage of $0.10 per share. Conversely, if the execution price is $49.90, that’s positive slippage—an unexpected advantage.
Slippage is more pronounced in fast-moving markets or when trading large volumes. It's particularly relevant in cryptocurrency trading, where prices can swing dramatically within seconds.
How Does Slippage Happen in Trading?
Slippage occurs due to the time delay between order submission and execution. Even with today’s high-speed electronic trading systems, this gap—though often milliseconds—can allow prices to shift significantly.
Several factors contribute to slippage:
- Market Volatility: Rapid price movements, often triggered by news events or economic data releases (like nonfarm payroll reports), increase the likelihood of slippage.
- Liquidity Levels: In markets with low trading volume, there may not be enough buyers or sellers at the desired price level, forcing execution at less favorable prices.
- Order Size: Large orders can deplete available liquidity at a given price point, requiring the remaining portion of the order to be filled at progressively worse prices.
- Bid-Ask Spread: A wide spread indicates lower liquidity and higher potential for slippage, especially when placing market orders.
For example, during major financial announcements or geopolitical events, markets often experience heightened volatility. Traders placing market orders during these times are more likely to encounter significant slippage.

Real-World Slippage Example
Imagine you want to buy 100 shares of Netflix Inc. The current bid price is $598.00, and the ask price is $599.10. You submit a market order expecting to pay $599.10 per share.
However, just as your order reaches the exchange, positive company news breaks—perhaps a successful product launch or strong quarterly earnings. Suddenly, demand surges. By the time your order executes, the ask price has risen to $599.17.
Your trade fills at this new price, meaning you pay $0.07 more per share than expected—a total slippage cost of $7 for 100 shares. This is a classic case of negative slippage caused by sudden market movement.
Conversely, if you had placed a sell order and prices dropped unexpectedly after submission, you might have sold at a higher price than current market rates—an instance of positive slippage.
Understanding these dynamics helps traders anticipate risks and adjust their strategies accordingly.
How to Avoid or Minimize Slippage
While it’s impossible to eliminate slippage entirely, several strategies can help reduce its impact:
1. Use Limit Orders Instead of Market Orders
A limit order allows you to specify the maximum price you’re willing to pay (for buys) or the minimum price you’ll accept (for sells). Unlike market orders, which execute immediately at prevailing prices, limit orders prevent trades from going beyond your defined thresholds—even if it means the order doesn’t fill completely.
2. Trade During High-Liquidity Periods
Markets with higher trading volumes tend to have tighter bid-ask spreads and more stable prices. For instance, major stock exchanges see peak activity during regular business hours. Similarly, in crypto markets, trading during overlapping session times (e.g., U.S. and European markets) can improve execution quality.
3. Avoid Trading Around Major News Events
Economic announcements like interest rate decisions, inflation data, or employment reports often trigger sharp price swings. Postponing trades until after such events can reduce exposure to sudden volatility and associated slippage.
4. Set Slippage Tolerance in Crypto Trading
Many cryptocurrency exchanges allow users to set a slippage tolerance percentage (e.g., 0.5% or 1%). If the execution price deviates beyond this threshold, the trade won’t go through. This feature gives traders greater control over unwanted price deviations.
5. Break Large Orders into Smaller Chunks
Instead of placing one large order, consider splitting it into smaller ones executed over time. This approach reduces market impact and improves average fill prices.
Frequently Asked Questions (FAQs)
Q: Can slippage ever be beneficial?
A: Yes—positive slippage occurs when a trade executes at a better price than expected. For example, buying below your target or selling above it improves profitability.
Q: Is slippage only a problem in cryptocurrency markets?
A: No. While crypto markets are especially prone due to high volatility and variable liquidity, slippage affects all financial instruments—including stocks, forex, and futures.
Q: Do all trading platforms offer slippage protection?
A: Most reputable platforms provide options like limit orders and customizable slippage tolerance settings, particularly in crypto trading interfaces.
Q: How does order type affect slippage?
A: Market orders are most susceptible because they prioritize speed over price. Limit and stop-limit orders offer more control and reduce the risk of adverse slippage.
Q: Can algorithmic trading reduce slippage?
A: Yes. Algorithmic strategies can break large orders into smaller pieces and execute them strategically across time and price levels to minimize market impact.
Q: Is zero slippage possible?
A: In highly liquid markets under stable conditions, slippage may be negligible—but achieving zero slippage consistently is rare, especially during volatile periods.
