Slippage happens when you execute a trade at a worse price than expected, due to market movement during the brief delay between order placement and fill, often from rapid bid-ask spread changes. You’ll see it in forex, like AUD/USD filling at 0.7028 instead of 0.7026 during news events, or stocks, such as Apple shares at $183.57 versus $183.53. It strikes most in illiquid markets, earnings reports, or fast moves like the 2010 Flash Crash. Minimize it by using limit orders, trading high-liquidity sessions, setting slippage tolerances, or avoiding major announcements. Delve further examples and strategies ahead.
What Is Slippage in Trading?
Slippage occurs when the price you expect for a trade differs from the actual executed price, as markets move between the moment you place your order and when it fills.
You encounter this difference, known as slippage, whenever rapid changes in the bid/ask spread—the gap between the highest buy price and lowest sell price—happen during the brief delay in execution, even just seconds long.
Slippage hits all asset classes, like equities, forex, bonds, futures, and cryptocurrencies, but strikes hardest in volatile or illiquid markets with thin trading volume.
It can benefit you positively: for a long trade, you snag a lower ask price; for a short, a higher bid.
Negative slippage hurts, though.
Say you buy 100 Apple shares expecting $183.53, but the ask jumps $0.04 to $183.57—you lose $4 total.
Any variance qualifies as slippage from market movement.
Causes of Slippage Across Markets
- You face slippage in forex like AUD/USD during news events, executing at 0.7028 instead of your 0.7026 target, from volatility and low liquidity in off-hours.
- In stocks, Microsoft’s bid-ask jumps from $109.05-$109.25 to $111.05 mid-order, shifting spreads rapidly.
- Crypto’s extreme volatility on decentralized exchanges impacts large orders, lacking liquidity for full matches.
- Low market depth across equities, bonds, and futures forces partial fills at inferior prices.
- Economic announcements, like Fed rate decisions or earnings reports, spike volatility, altering bids and asks abruptly.
Slippage Examples in Forex and Stocks
When you place market orders in volatile conditions, slippage often strikes unexpectedly, as seen in real forex and stock trades.
You expect 100 Apple shares to execute at the ask of $183.53, but the bid/ask spread shifts to $183.54/$183.57, filling your order at $183.57—a $0.04 per share, or $4 total, negative slippage.
In forex, your long AUD/USD order at $0.7026 executes at $0.7028 due to low liquidity, costing 2 pips in negative slippage.
Selling 5 Microsoft CFD contracts short at the $109.05 bid? It fills at $111.05 as spreads widen, amplifying losses.
Yet, positive slippage helps: you buy EUR/USD at 1.2045, better than the expected 1.2050.
Buying GBP/USD at 1.4040? Volatility pushes it to 1.4045, causing negative slippage.
When Slippage Is Most Likely to Occur
Market volatility spikes during major economic releases, like non-farm payroll reports, or central bank interest rate announcements, making slippage most likely then as prices swing wildly.
Slippage, defined as the difference between your expected price and the executed price, hits hardest when markets lack liquidity or react sharply to news.
You’ll encounter it most in these scenarios:
- Illiquid markets with low trading volume, where insufficient market depth prevents fills at your target price.
- Company earnings reports or surprises like CEO changes, causing rapid bid/ask spread shifts.
- Large market orders during fast moves, such as the 2010 Flash Crash, overwhelming order books.
- Market openings or closings, when price gaps form from overnight news.
- Low-activity periods, like off-peak forex sessions or weekends, with thin participation.
Strategies to Minimize Slippage
Traders minimize slippage by adopting targeted strategies that prioritize control, timing, and platform features.
You start by using limit orders, which execute at your specified price or better, unlike market orders that risk negative slippage through worse prices.
However, limit orders may not fill if prices don’t reach your limit.
You trade during high liquidity periods, like US exchange openings or London forex sessions, where tight bid-ask spreads—the difference between buy and sell prices—ensure fast execution.
Set maximum slippage tolerance on platforms, such as 0.5% or 1%, to cancel orders exceeding that threshold.
Avoid major events, like Fed interest rate announcements or earnings reports, when volatility spikes slippage.
Opt for guaranteed stop-loss orders, which execute at your exact stop price for a small premium, eliminating slippage risk.
Frequently Asked Questions
Can Slippage Be Positive?
Yes, slippage can be positive—you buy assets cheaper or sell higher than expected when market prices move favorably. You encounter it during volatile trades, but you minimize negatives by using limit orders, trading in liquid markets, and avoiding peak volatility times.
How Does Slippage Differ in Crypto vs. Stocks?
You experience greater slippage in crypto due to low liquidity and volatile prices on DEXs, causing bigger gaps between expected and executed prices. In stocks, high liquidity on centralized exchanges minimizes it, so you face less during trades.
What’s Slippage Tolerance on DEXS?
You set slippage tolerance on DEXs as the maximum price change you’re willing to accept during a trade. You adjust it higher for volatile tokens to guarantee execution, but you risk worse prices; lower it for stability on calmer pairs.
Does Slippage Affect Stop-Loss Orders?
You set stop-loss orders at specific prices, so slippage doesn’t affect them directly. You execute trades at market rates only when the stop triggers, facing slippage then, but your order’s trigger price stays precise.
How to Calculate Slippage Impact on Profits?
You calculate slippage’s impact on profits by subtracting actual fill price from your expected price, then multiply by position size and trade volume. For example, if you expect $100 but fill at $102 on 100 shares, you lose $200—deduct that from gross profits.
Conclusion
You understand slippage as the difference between your expected trade price and the executed price, caused by market volatility, low liquidity, or high volatility periods like news releases. To minimize it, you use limit orders, which execute only at your specified price or better, avoiding market orders during volatile times. You also trade in highly liquid markets, avoid peak volatility, and choose brokers with fast execution. These steps guarantee you control costs and execute trades precisely.
