What is Slippage?
Slippage occurs when the execution price of a trade is different from its requested price. It occurs when the market orders could not be matched at preferred prices – usually in highly volatile and fast-moving markets prone to unexpected quick turns in certain trends.
Any variation between the executed price and the intended price is considered a slippage. The slippage may be zero, positive, or negative, and it depends on whether the order is a buy or sell, or whether the order is for opening or closing a position, and on the direction of price movement. Slippage may occur when a huge market order is finalized, but there is an insufficient volume at the selected price for maintaining the bid/ask spread.
Summary
- Slippage occurs when an order is executed at a price greater or lower than the quoted price, usually happening in the periods when the market is highly volatile, or market liquidity is low.
- The exposure to slippage risk can be minimized by trading during hours of highest market activity and in low volatility markets.
- A positive slippage gets an investor a better price than expected, while a negative slippage leads to a loss.
Occurrence of Slippage in Trading Market
Slippage usually occurs in periods when the market is highly volatile, or the market liquidity is low. Since the participants are fewer in markets with low liquidity, there is a wide time gap between the placement and execution of an order. The volatile markets experience quick price movements, even quicker than filling an order. Hence, the price of an asset may change during the time gap, which results in slippage.
In forex trading, slippage normally occurs on less popular currency pairs – such as AUD/JPY – since highly popular currency pairs come with low volatility and high liquidity. For example, an investor decides to open a position on AUD/USD, which is a highly volatile currency pair, at the quoted price of $0.6025. However, the price might’ve increased to $0.6040 in the time gap between the submission and execution of the order. The investor will experience a slippage since he/she will be trading at a higher price than anticipated.
Slippage often occurs during or around major events such as announcements regarding interest rates and monetary policy, earnings report of a company, or changes in the management positions. The events increase market volatility, which can increase the chances of investors experiencing slippage.
When investors hold positions after markets close, they can experience slippage when the market reopens. It happens because the price may change due to any news event or announcement that could’ve happened while the market was closed.
Minimizing the Impact of Slippage
There are various ways that an investor can minimize the consequences of slippage. Some of these are as follows:
1. Trade in low volatile and high liquidity markets
The prices in low volatile markets usually do not change quickly, and high volatile markets have many market participants on the other side of the trade. Hence, if investors trade in highly liquid and low volatile markets, they can limit the risk of experiencing slippage.
Moreover, the chances of slippage can be reduced by trading during the periods experiencing the most activity since liquidity will be the highest during that time. It increases the chances of the trade getting executed quickly at the requested price. For example, the largest volume of trades is executed in the stock markets when the major U.S. stock exchanges are open. The forex trading experiences the largest volume during the open hours of the London Stock Exchange (LSE).
2. Employ guaranteed stops and limit orders
Since an order with a guaranteed stop will be executed at the requested price, slippage risk is prevented. However, a premium attached to the guaranteed stop will be incurred if it is triggered. A limit order can help lessen the risk of slippage when investors enter a trade or seek to gain returns from a successful trade.
When a limit order is activated, the order will be filled at the specified price or a favorable price. It implies that execution of a sell order takes place at the desired price or a higher price, whereas the execution of a buy order takes place at the specified price or a lower price.
3. Check how the trading providers treat slippage
While some providers will execute the orders even if the price does not match the requested price, others will execute the order as long as the price difference is within the investor’s tolerance level. Once the price difference falls outside the tolerance level, the order will be rejected, and resubmission will be required at a new price.
