Definition of Slippage


Slippage occurs when the price at which a trade is executed differs from the expected price of the trade. Various factors, such as market volatility, liquidity, and delays in order execution, can cause slippage. This article will examine the different types of slippage, how to avoid it, and its impact on trading performance.


Types of Slippage


There are two main types of slippage - positive and negative. Positive slippage appears when a trade is executed at a better price than expected, while negative slippage occurs when a trade is conducted at a worse price than expected. While positive slippage can be a pleasant surprise for traders, negative slippage can be costly and erode profits.


Let's look at a real-life example to understand the impact of slippage better. Imagine a trader who wants to buy a stock at $50 per share. They place a market order, but the trade is executed at $52 per share due to market volatility and low liquidity. This results in negative slippage of $2 per share. If the trader had used a limit order instead, they could have avoided this slippage and purchased the stock at their desired price.



Factors that Contribute to Slippage


Various factors, including market liquidity, trading sessions, market volatility, and delays in order execution, can cause slippage.

Market liquidity refers to the number of buyers and sellers in the market and how quickly and easily a trader can buy or sell an asset without affecting its price. In low-liquidity markets, fewer buyers and sellers may make it harder to execute trades at the desired price, which can result in slippage.


Traders should be aware of the trading sessions for the markets they are trading and adjust their strategies accordingly. Slippage may be more common during specific trading sessions, such as during the open or close of a trading day, when there may be a higher volume of orders being executed.


Market volatility is the degree of price variation over time and can be influenced by a range of factors such as news events, economic indicators, and political developments. During periods of high volatility, there may be rapid price movements and changes in market sentiment, which can impact the speed and efficiency of order execution and result in slippage.


Market gaps are a specific type of market volatility where there is a sudden shift in prices, resulting in a gap in the price chart. These sudden shifts in price can result in significant slippage, mainly if a trader uses a market order.


Delays in order execution can also cause slippage, particularly for traders who use automated trading systems. To minimize the impact of delays in order execution, traders should use reliable trading platforms and internet connections and monitor their orders closely to ensure they are executed promptly.


How to Avoid Slippage


While traders cannot always avoid slippage altogether, there are some strategies they can use to minimize its impact:


1. Use limit orders rather than market orders: One way to minimize the impact of slippage is to use limit orders, which allow traders to set a specific price at which they are ready to buy or sell a security. By using a limit order, traders can ensure that their trades are executed at a specific price or better. However, there is a risk that the limit order may not be filled if the market does not reach the specified price.


2. Avoid trading during periods of high volatility: High volatility can increase the likelihood of slippage. Rapid price movements can cause trades to be executed at prices different from the expected. By avoiding trading during periods of high volatility, traders can reduce their exposure to slippage. It's better to stay out of the market during significant news announcements or events likely to impact market sentiment.


3. Use stop-loss orders to limit losses: A stop-loss order allows traders to limit their losses in the event of unexpected price movements. By setting a stop-loss order, traders can specify the maximum amount they are willing to lose on a particular trade. If the security price reaches the specified level, the stop-loss order is triggered, and the trade is automatically closed. This can help to protect traders from significant losses due to slippage.


In addition to these strategies, traders can also consider using execution algorithms, which can help minimize slippage by attempting to execute trades at the best price.



Impact on Long-Term Performance


Excessive slippage can erode profits over time and make it difficult to achieve consistent returns. Traders should be aware of the potential impact of slippage on their long-term trading performance and adjust their strategies accordingly.


To evaluate their results and identify the impact of slippage on their trades, traders can use a variety of tools and metrics. One helpful tool is a trade log, which allows traders to record the details of each transaction, including the entry and exit price, time, and any slippage that occurred. By reviewing their trade log and analyzing their trades, traders can identify patterns and adjust their trading strategies to minimize slippage and improve their overall performance.


Traders can also use the win-loss ratio to monitor their profitability. It measures the percentage of profitable trades compared to losing trades. A high win-loss ratio can indicate that a trader's strategy is effective and that slippage is not significantly impacting their performance. Conversely, a low win-loss ratio may suggest that slippage significantly affects the trader's performance and that adjustments to their strategy may be necessary.



Slippage is an important concept for traders to understand. By using limit orders, avoiding trading during periods of high volatility, and using stop-loss orders to limit losses, traders can reduce their exposure to slippage. Additionally, traders can achieve consistent returns over time by adjusting their trading strategies and understanding the potential impact of slippage on their long-term performance.
