The Importance of Understanding Slippage in Forex Trading

The foreign exchange market is known for its complexities, one of which is slippage. This seemingly insignificant phenomenon is often ignored by novice traders, but it holds considerable importance in shaping trading outcomes. Noteworthy is that every detail matters in this realm, even the minuscule fluctuations in prices.

Strategies like scalping or pipsing are often based on these marginal fluctuations, aiming to capitalize on a few pips or tens of pips. However, imagine the scenario when during the execution of each order, a delay occurs, causing the price to shift even by one pip. This one pip is an addition to the ‘lost’ category. Now, magnify this situation to about a hundred trades in one trading session; that’s a hundred points lost in a day. Such accumulated losses emphasize the need to understand slippage, why it occurs, and how it can potentially be managed.

The Mechanics of Slippage

Broadly speaking, slippage refers to the discrepancy between the price at which an order was placed and the price at which it was executed. In simpler terms, it represents a ‘jump’ in quotes between two events. Various factors can trigger this, ranging from significant market-moving news to sudden shifts in demand and supply dynamics.

Slippage can sometimes be sizable, running into several hundreds of points. However, the likelihood of a trader experiencing price slippage is largely dependent on the type of orders placed. Forex trading offers two types of orders – limit orders and stop orders.

Limit orders are executed at a set price that is more favorable than the current price when the order is placed. In contrast, stop orders are executed at a less favorable price than the current price at the time of the order placement. This difference in functionality between the two types of orders illuminates why a stop order cannot be immediately placed in the market, as it would be instantly executed on terms unfavorable to the trader.

To illustrate, consider a trader setting a stop to buy an asset at 1.2315. The order enters the market only when the asset’s value first reaches 1.2315. However, prices do not always change uniformly and may not necessarily increase by exactly one pip. Suppose the nearest price is 1.2318, the order will be executed at this price. The difference between the price set by the trader and the actual execution price (3 pips in this example) is the slippage.

This phenomenon is often confused with the spread, which is the difference between the bid and ask price. Technically, a specific case of slippage is a gap when a significant gap forms between the closing and opening prices at the market opening (for example, after the weekend).

Types of Slippage

Since prices can move in any direction, slippage can be categorized as positive or negative. Positive slippage is relatively rare but occurs when the price of an asset decreases when a buy order is placed or increases when a sell order is placed. In contrast, negative slippage is much more common and occurs when a buy order is executed, and the actual asset price is higher than the declared price, or vice versa.

Factors Causing Slippage

Understanding the causes of slippage is critical to devise strategies for protection against potential slippage losses. These causes can be broadly divided into volatility, the speed of order execution, the type of order execution, and the type of trading account.

Volatility is a financial measure indicating the change in an asset’s value over time. High volatility indicates more discrete (jumpy) quotes on the chart, increasing the likelihood of price slippage. Meanwhile, the speed at which your orders are executed also plays a significant role, as the asset’s value can change during this time, resulting in order closure at a price different from the one specified.

The type of order execution also influences slippage. As we have mentioned earlier, limit orders are executed strictly at the set price, but their execution is not guaranteed, while stop orders (market orders) are executed in full volume, but price slippage is possible. Finally, the type of trading account used can also affect slippage.

Understanding the Link Between Slippage and Liquidity

Liquidity, defined as the ease with which an asset can be sold quickly at a price close to the market value, plays a significant role in determining slippage. More liquid markets usually have less noticeable price slippage because prices change frequently but often insignificantly. On the other hand, less liquid markets are riskier in terms of possible losses due to slippage because price spikes in these markets tend to be sudden and significant.

Dealing with Slippage

While it’s true that slippage can sometimes lead to unfavorable outcomes, it’s essential to remember that it is a normal part of the forex market. It’s not necessarily a bad thing, as it indicates the reality of the market, especially when trading on higher volume. What’s important is understanding how it works and how to handle it.

FAQs to summarize the article

What is Slippage in Trading?
Slippage in trading occurs when an order is executed at a different price than it was when it was opened. There are various reasons for slippage, including significant market news or the type of orders placed (limit and stop). The size of slippage can sometimes be significant, even up to several hundreds of points.
What’s the difference between slippage and spread in trading?
Spread is the difference between the bid and ask price, whereas slippage is the difference between the expected price of a trade and the price at which the trade is executed. The spread is set by the broker and is always present in trading, while slippage is influenced by external factors and only appears periodically.
What are Positive and Negative Slippage?
Positive slippage is when the price of the asset decreases when the order is placed to buy or rises when the order is placed to sell. Negative slippage, which occurs more frequently, is when the buy order is executed and the actual price of the asset is higher than the declared price, or when the sell order is executed and the actual price is lower than the declared one.
What causes slippage in trading?
The main causes of slippage in trading are volatility, the speed of order execution, the type of order execution, and the type of trading account. High volatility and slower execution times increase the likelihood of slippage, as do certain types of order execution and trading accounts.
How is Slippage related to liquidity in trading?
Liquidity refers to the ability to sell an asset quickly at a price close to its market value. Slippage is less noticeable in more liquid markets because prices change constantly but not critically. Conversely, less liquid markets, like precious metals or unpopular altcoins, can experience sudden and significant price spikes, leading to more pronounced slippage.
How can I minimize potential losses caused by slippage?
To minimize potential losses from slippage, consider the trading conditions of different brokers, identifying those with fast execution times and slippage limitation functions. Avoid trading during times of high market volatility and around the release of macroeconomic news, which can cause price fluctuations. Choose a trading account type, such as ECN, HDD, or STP, that offers fast execution speeds and minimal slippage.
Is Slippage always bad in trading?
While slippage can lead to losses, it’s not always bad. Slippage is a normal part of trading and indicates realistic market activity. Positive slippage, though rarer, can lead to additional gains. Slippage can also signal that trading is being carried out on the interbank market.
What is the difference between limit and stop orders in trading?
Limit orders are executed at a set price that is more favorable than the current price when placing the order. On the other hand, stop orders are executed at a price less favorable than the price at the time of the order placement. Limit orders represent a desire to open a position at the most profitable price, while stop orders are a kind of insurance mechanism to avoid financial losses in case the price deviates from the predicted one.
