Trading is never an easy job for anyone. No matter how well you prepare yourself, there will always be unexpected roadblocks. In trading, price movements are front and centre of all investor activity. Rises and falls in prices are inherently part and parcel of the fluctuating markets. Our algo trading software employs advanced risk management techniques to monitor and respond to price volatility, ensuring optimal trading outcomes.
The market sometimes comes with an unexpected bonus and sometimes with unwelcome surprises (depending on which way it goes), which is termed ‘slippage’. Whether you are trading stocks, Forex, or futures, slippage inevitably happens.

What Is Slippage?
Slippage occurs when the execution price of a trade is different from its requested price.
Any variation between the executed price and the intended price is considered as slippage. The slippage may be zero, positive, or negative and also depends on whether the order is a buy or sell, whether the order is for opening or closing a position, and even the direction of price movement.
Slippage normally happens during high periods of volatility because orders cannot be matched at desired prices due to the fast pace of price movements in the financial markets at such periods. Hence, there is a higher chance that slippage may occur due to the delay that exists between the point of placing an order and the time it is completed.
How Slippage Occurs
Anytime a buy or sell order is placed, the order is executed at the best available price offered on an exchange or by a market maker, which can produce results that are equal to, more favourable, or less favourable than the intended execution price. Thus, considering the actual execution price vs. the intended execution price, the order execution can be categorised as no slippage, positive slippage, or negative slippage.
As market prices can change quickly, slippage can occur during the delay between when a trade is ordered and when it is executed. Slippages occur with market orders or pending orders, such as stop orders (including stop loss orders), which are executed as market orders when the price reaches the set level.
A limit order prevents negative slippage, but it carries the inherent risk of the trade not being executed if the price does not return to the limit level. This is more likely to happen in situations where market fluctuations occur more quickly, which limits the amount of time for a trade to be completed at the intended execution price.
Examples of Slippage
- No slippage: Let’s say you want to buy XYZ stock, and the bid/ask prices are quoted as ₹50.50/₹50.54 on the broker’s platform. You place a market buy order for 200 shares, and the order gets filled at ₹50.54, which is the asking price you intended to buy at. So, there is no slippage in this case.
- Negative slippage: Let’s assume that the XYZ stock, which was quoted as ₹50.50/₹50.54 on the broker’s platform, was filled for your buy market order at ₹50.95. In this case, the buy order was filled at a worse price than intended. So, there was a negative slippage of ₹0.41.
- Positive slippage: In this case, you place your buy market order, expecting it to fill at ₹50.54 as was quoted on the broker’s platform (₹50.50/₹50.54), but the order was filled at a lower price, say ₹50.41. So, you have a positive slippage of ₹0.13. Interestingly, if the price came up again to around the price quote you saw earlier, you are invariably in profit early on.
Why Does Slippage Occur?
While it’s impossible to avoid some forms of slippage completely, there are certain situations in which slippage is more likely to occur. These situations include:
- Using delayed quotes or slow order entry methods increases slippage.
- Trading in stocks or markets with higher volatility boosts your risk of slippage.
- Entering larger orders will increase the amount of slippage you have.
- Trading stocks with low volume leads to more slippage.
- Trading after regular market hours can also lead to slippage.
- Slow Internet or outdated devices also increase the chances of slippage.
Let’s look at some of these in detail:
1. Delays Increase Slippage
Back before the Internet transformed investing, slippage due to delays was not a surprise. It was expected because significant delays were unavoidable. You used to look at a newspaper to get your prices, and then you would pick up the phone and call your broker to put in your order. They would write your order down, confirm it to you, and then call or fax it to their trading department. Fast forward to today, when many aspects of the markets are automated using computer networks. This has made it easier to get a current price quote, and it has created many options for entering an order directly into a broker’s system online. This leaves less time for the market to change – in other words, less time for slippage. But still, in today’s fast-moving era, if you are using an outdated device, a slow Internet facility, or a device which is employed in multiple tasks simultaneously, the chances of slippage increase.
2. Volatility Increases Slippage
Trading a volatile security also increases the risks of slippage. Volatility essentially means that the price of a security is experiencing more significant changes. So, higher volatility means that the price is more likely to fluctuate between when you submit an order and when that order is ultimately fulfilled.
3. Order Size and Volume Affect Slippage
Order size and volume also play a role in slippage. Imagine you are entering a small buy order. You glance at the bid/ask spread, the asking price suits you, and you click on buy. For example, 400 shares of XYZ stocks are available, and you wish to buy only 350 shares. Because you are only buying a few shares, you can reasonably expect that there are enough shares at the current asking price to fill your order. In that case, you will have avoided slippage.
But if you enter a large market order, for example, suppose 200 shares of XYZ stocks are available at ₹100/share, 200 shares for ₹500/share, and 200 shares are available at ₹1000/share. Now, you are more likely to buy all available shares from multiple offers at ascending prices, which will drive your average price per share up from what the spread is currently showing you. In that case, you experience slippage.
4. Day Traders Need to Consider Slippage More
While there are many different types of traders, day traders and scalpers need to consider slippage to a much greater extent than someone who is going along with a stock or Exchange-Traded Fund (ETF) because they are making more frequent trades. They are often trying to profit on much smaller price changes, so even a few cents of slippage takes a more substantial chunk of their profit margin.
How to Minimise Slippage
Now that we’ve seen the causes of slippage from multiple angles, it should be much easier to see the solutions.
Trader-Side Remedies
1. Reduce Delays
Don’t just submit market orders by calling your broker. Not only is it usually more expensive to fulfil an order via phone call, but it typically takes longer for your order to get filled. Instead, take advantage of online trading platforms that generally allow you to reduce the time delay from minutes to 1/10th of milliseconds with a fast Internet and dedicated device for trading.
2. Avoid Volatility
You can reduce slippage by avoiding volatile stocks and markets altogether. You can also limit your trading activity during planned news events such as company earnings reports or government market reports.
3. Use Limit Orders
Consider using limit orders instead of market orders. A limit order allows you to set a specific price as a condition of the order’s fulfilment. If your pricing condition isn’t met, then the order doesn’t get processed.
Broker-Side Remedies
Perhaps the greatest challenge regarding slippage is that many of its drivers are not within a trader’s control.
1. Automation:
One way to greatly reduce latency and slippage is to automate your trading strategies. Automation incorporates trade selection, order placement, and trade management into one automatic function. In addition, automated strategies are often utilised via broker-furnished co-located servers, further increasing precision (check out our previous blog for understanding co-location in detail).
2. Robust Trading Software:
Advanced order types, bracket orders, and low-latency charting software are strong ways to improve trade-related efficiency. Having a broker that supports the ideal platform for the execution of your advanced trading strategies is a must.
