Explore the meaning of slippage in trading, its causes, impact on traders, and ways to minimise it.
Slippage, in the context of trading, refers to the difference between the anticipated price of an order and the actual price at which it is executed. This price discrepancy can occur due to market volatility, low liquidity, or the speed at which orders are processed. Slippage can be positive, where the execution price is better than expected, or negative, where the execution price is worse
This article breaks down the concept of slippage, its types, causes, and how traders can work around it to make better decisions.
Slippage occurs when the actual price of a trade differs from the expected price. It is more common in volatile markets or when executing market orders in low-liquidity conditions.
For example, if you place a buy order for a stock at ₹500, but the trade gets executed at ₹503, you have experienced a slippage of ₹3.
Slippage can be either positive or negative, depending on whether the trade is executed at a better or worse price than expected.
There are several factors that contribute to slippage during trade execution:
When prices change rapidly, orders may be filled at different levels than initially expected.
Market orders, which are executed at the best available price, are more prone to slippage compared to limit orders, which specify a maximum or minimum price.
When there aren’t enough buyers or sellers at a particular price level, orders may be executed at the next available price, leading to slippage.
Low volume in a stock can mean larger price gaps between successive bids and offers, increasing the slippage risk.
Even a few seconds of delay in execution, often due to poor internet speed or server latency, can result in significant price differences.
Slippage happens when the execution price of a trade differs from the price you expected. This can occur due to market volatility, low liquidity, or lag between order placement and execution. It can go either way—yielding a better price (positive slippage), an exact match (no slippage), or a worse price (negative slippage) than anticipated. Using limit orders instead of market orders helps avoid negative slippage, though it may mean your order doesn’t execute at all.
Slippage is broadly categorised into three types:
Type |
Description |
|---|---|
Positive |
Trade executed at a better price than expected |
Negative |
Trade executed at a worse price than expected |
Neutral |
Trade executed at the exact expected price (no slippage) |
Note: Positive slippage is rare but can occur in fast-moving, high-volume markets where favourable price movements happen quickly.
The formula to calculate slippage is:
Slippage = Actual Execution Price – Expected Price
If you expected to buy a stock at ₹100 but it got executed at ₹101.50, then:
Slippage = ₹101.50 – ₹100 = ₹1.50 (negative slippage)
If it was executed at ₹98.50:
Slippage = ₹98.50 – ₹100 = -₹1.50 (positive slippage)
Slippage can significantly affect short-term traders, especially those using strategies like scalping or intraday trading where even small price differences matter.
Negative slippage adds to the cost of trade, reducing overall profitability.
For automated or algorithmic traders, large or frequent slippage can deviate from intended strategy execution.
In volatile markets, consistent slippage can amplify trading risks and erode capital over time.
In Futures & Options trading, slippage becomes even more critical due to:
Lower liquidity in certain contracts
Wider bid-ask spreads
Rapid time decay in options
Traders in derivatives markets often use limit orders or place trades during high-volume sessions to reduce slippage.
While slippage cannot be completely avoided, several measures can help reduce its impact:
Limit orders help ensure that trades are only executed at a price you are comfortable with, avoiding major deviations.
Securities with high daily trading volume are less likely to experience slippage due to tighter spreads and consistent price discovery.
Market announcements often cause sudden price spikes or drops. Avoid trading at such times unless necessary.
Platforms with better infrastructure and faster execution times help reduce latency-based slippage.
Before placing trades, check the bid-ask spread and market depth to anticipate potential slippage levels.
While both slippage and spread affect your effective trade price, they are not the same:

Definition |
Difference between bid and ask price |

Occurrence |
Always present in markets |
Occurs during fast-moving or illiquid conditions |
Control |
Can be minimised by trading in liquid assets |
Can be reduced using limit orders |
Slippage is an important but often overlooked aspect of trading, especially for active traders and short-term investors. While it may seem like a small amount per trade, its cumulative impact can be substantial over time. Understanding slippage, its causes, and ways to manage it is vital for improving trade execution and optimising results.
By using appropriate tools and strategies, traders can reduce slippage and stay closer to their planned entry or exit prices.

Slippage occurs because of rapid market movements, low liquidity, or delays in order execution.
No. Slippage can be positive, negative, or zero, depending on whether the trade is executed at a price that is higher, lower, or the same as the expected price at the time of order placement.
Yes. Limit orders allow you to set a maximum or minimum price for execution, helping avoid unfavourable prices.
Not significantly. Since long-term investors focus on broader trends, small price differences have minimal impact.
Yes. Options often have wider bid-ask spreads and lower liquidity, which makes them more prone to slippage.
Slippage, the difference between the expected and executed trade price, affects long-term trades by potentially eroding overall returns through cumulative small discrepancies over time. In volatile markets, it can compound costs for position building or unwinding, though its relative impact diminishes compared to short-term trades due to extended holding periods and fewer transactions.
Slippage can be measured as the difference between the expected order price (such as the limit price) and the actual execution price, expressed as a percentage or basis points. Traders use tools like execution reports, slippage logs in trading software, or post-trade analysis to track averages across orders, helping assess broker efficiency and market conditions.
Yes, many trading platforms offer features like limit orders to control execution prices, slippage tolerance settings for algorithmic trades, and real-time market depth views to anticipate volatility. Advanced ones include iceberg orders or post-trade slippage analytics, aiding users in minimising impacts under SEBI-regulated environments.
