Slippage is a common yet often misunderstood phenomenon in financial markets, especially among traders navigating volatile assets like cryptocurrencies. While many instinctively view slippage as a negative outcome, understanding its mechanics can empower traders to make smarter decisions—minimizing risk and even capitalizing on favorable execution shifts. This guide breaks down what slippage is, why it happens, the two main types, and actionable strategies to manage or avoid it effectively.
What Is Slippage?
Slippage occurs when the price at which a trade is executed differs from the expected or requested price at the time of order placement. This discrepancy typically arises during periods of high market volatility or low liquidity, where rapid price movements prevent orders from being filled at the desired level.
For example, imagine placing a buy order for a cryptocurrency at $100. Due to fast-moving market conditions, your order might instead execute at $100.50—or even $99.70, depending on supply and demand dynamics. While these differences may seem minor, they can significantly impact trading performance over time, especially for high-frequency or large-volume traders.

Why Does Slippage Happen?
Slippage is not a flaw in trading systems—it's a natural outcome of market mechanics. Three primary factors contribute to its occurrence:
- High Market Volatility – Rapid price swings make it difficult for exchanges to fulfill orders at exact prices.
- Low Liquidity – Fewer buyers and sellers mean thinner order books, increasing the chance that your order will "slip" to the next available price.
- Large Order Size – Orders that exceed available volume at a given price level must be filled across multiple price points, leading to average execution prices different from the initial quote.
Markets like cryptocurrency are particularly prone to slippage due to their 24/7 operation, global participation, and frequent news-driven volatility. However, slippage also occurs in traditional markets—such as forex, stocks, and futures—especially during major economic announcements or geopolitical events.
Understanding these triggers helps traders anticipate when slippage risk is highest and adjust their strategies accordingly.
The Two Types of Slippage
Contrary to popular belief, slippage isn't always detrimental. Depending on the direction of the price movement, it can be either positive or negative.
1. Positive Slippage
Positive slippage occurs when your order executes at a better price than expected. For instance:
- A buy order placed at $100 fills at $99.50.
- A sell order set at $200 executes at $201.
This type of slippage benefits traders by improving profit margins or reducing entry costs. It’s more likely when using limit orders, which only execute at or better than your specified price. While not guaranteed, positive slippage reflects favorable market movement just before execution.
2. Negative Slippage
Negative slippage happens when execution occurs at a worse price than intended:
- Buying higher than planned (e.g., buying at $101 instead of $100).
- Selling lower than expected (e.g., selling at $198 instead of $200).
This scenario often affects market orders, which prioritize speed over price precision. During sudden news events or flash crashes, negative slippage can lead to significant unintended losses—especially in illiquid markets.

How to Minimize or Avoid Slippage
While eliminating slippage entirely is nearly impossible, several proven techniques can reduce its frequency and impact.
1. Trade During Low Volatility and High Liquidity Periods
Markets with stable prices and deep order books reduce the likelihood of large execution gaps. For crypto traders, this often means avoiding major announcement windows (like Fed decisions or protocol upgrades). In traditional markets, steering clear of opening/closing hours or economic data releases can help.
High liquidity ensures that there are enough counterparties to absorb your order without drastic price changes. Major cryptocurrencies like Bitcoin and Ethereum generally offer tighter spreads and lower slippage compared to smaller altcoins.
2. Use Limit Orders Instead of Market Orders
A limit order allows you to define the maximum price you're willing to pay (for buys) or the minimum you'll accept (for sells). Unlike market orders, which execute immediately at current market rates, limit orders wait for matching prices—giving you greater control.
While this may result in unfilled orders during fast-moving markets, it protects against negative slippage. For disciplined traders focused on risk management, this trade-off is often worthwhile.
3. Set an Appropriate Slippage Tolerance
Most cryptocurrency trading platforms include a slippage tolerance setting—usually adjustable between 0.1% and 5%. This feature lets you define the maximum acceptable deviation from your target price before an order is rejected.
For example:
- Set at 1%, a buy order for $1,000 won’t execute if the price rises above $1,010.
- Useful during high-volatility events to avoid unfavorable fills.
However, be cautious: overly tight tolerances may cause failed transactions, especially with high gas fees on blockchain networks. Each rejected transaction still consumes network resources, increasing overall trading costs.

Frequently Asked Questions (FAQ)
Q: Can slippage occur in stock trading?
A: Yes. While less common than in crypto due to higher liquidity and regulated trading hours, slippage can still happen during earnings announcements, market openings, or flash events.
Q: Is slippage always bad?
A: No. Slippage can be positive (better-than-expected execution) or negative. The key is managing exposure through proper order types and timing.
Q: Does using a limit order guarantee no slippage?
A: Limit orders prevent negative slippage by design but may not execute at all if the market doesn’t reach your specified price.
Q: How do I know how much slippage I’ve experienced?
A: Most trading platforms display the “average fill price” versus “intended price” in your order history, showing the exact slippage amount.
Q: Should I set slippage tolerance to 0%?
A: Not recommended. A zero percent tolerance may prevent execution entirely during normal market fluctuations. A small buffer (e.g., 0.1%–0.5%) improves success rates without significant risk.
Q: Which assets are most prone to slippage?
A: Low-volume cryptocurrencies, penny stocks, and exotic currency pairs typically have higher slippage due to shallow order books and erratic price action.
Final Thoughts
Slippage is an inherent part of trading across all financial markets—but it doesn’t have to hurt your bottom line. By understanding its causes and leveraging tools like limit orders and slippage tolerance settings, traders can maintain greater control over their entries and exits.
Timing your trades during stable, liquid market conditions further reduces unwanted surprises. Whether you're trading crypto, forex, or equities, awareness and preparation are your best defenses against costly execution gaps.
Stay proactive, use smart order types, and always consider the liquidity landscape before hitting "buy" or "sell."
