In the fast-moving world of financial markets, even a fraction of a second can alter the outcome of a trade. One such micro-level phenomenon that every trader—beginner or professional—must understand is slippage. It often goes unnoticed, but its effect on profitability and risk management is profound.
This detailed guide by Lares Algotech explores what is slippage in trading, its meaning, causes, real-world examples, and ways to minimize its impact—especially in the age of algorithmic and high-frequency trading.
What is Slippage in Trading?
Slippage occurs when a trade is executed at a price different from the one the trader expected. It typically happens when market prices move quickly between the time an order is placed and the time it is executed.
For example, if you place a buy order for a stock at ₹100, but it gets executed at ₹100.25, the ₹0.25 difference is slippage.
Slippage can be positive (better than expected price) or negative (worse than expected price). In most fast-moving or volatile markets, traders experience negative slippage.
Why Slippage Happens in Trading
Slippage arises mainly due to market volatility, low liquidity, and execution delays. Here are the core reasons:
- Market Volatility: During news events or data releases, prices can change multiple times per second.
- Liquidity Gaps: When there aren’t enough buy/sell orders at a specific price level, your order may fill at the next available level.
- Latency & Order Transmission: Delays in order routing between your trading platform and the exchange can cause missed price levels.
- Order Type: Market orders are most prone to slippage since they execute immediately at the best available price.
Types of Slippage
Positive Slippage
Occurs when you get a better price than expected.
Example: You place a buy order at ₹100, but it executes at ₹99.90.
Negative Slippage
Occurs when the execution price is worse than expected.
Example: You place a buy order at ₹100, but it executes at ₹100.20.
No Slippage
Occurs when the trade executes exactly at your desired price. This is rare in volatile markets.
Slippage in Different Markets
Stock Market
During high-volume periods like earnings announcements or market openings, order books fluctuate quickly, causing slippage.
Forex Market
Currency pairs trade 24×7 globally, and major news events (like U.S. jobs data or central-bank decisions) can cause huge slippage, especially in low-liquidity sessions.
Commodity Market
Futures contracts for commodities like gold or crude oil show slippage when demand/supply imbalances occur.
Crypto Market
Due to 24-hour trading and fragmented liquidity across exchanges, slippage is common—especially with large market orders.
Example of Slippage in Trading
Let’s understand through a real-world scenario:
- You place a market order to buy 500 shares of XYZ Ltd. at ₹200.
- However, the available liquidity at ₹200 is only 200 shares.
- The remaining 300 shares fill at ₹200.50 and ₹201 due to the next available sellers.
- Average execution price: ₹200.67
- Slippage: ₹0.67 × 500 = ₹335
Even small per-share slippage can accumulate into substantial costs for active traders.
How Market Orders vs Limit Orders Affect Slippage
| Order Type | Definition | Impact on Slippage |
| Market Order | Executes instantly at best available price. | High slippage risk in volatile markets. |
| Limit Order | Executes only at or better than a specified price. | Prevents slippage but may cause missed trades. |
| Stop Order | Converts to market order when a trigger price is reached. | Can result in major slippage during sharp price moves. |
Traders at Lares Algotech often use smart order-routing algorithms to balance speed and price accuracy, thereby reducing slippage without missing opportunities.
How to Calculate Slippage
The formula is simple:
Slippage = Executed Price – Expected Price
Example:
If you placed a buy order expecting ₹150 and it executed at ₹150.40, your slippage is ₹0.40 per share.
If you bought 1000 shares, total slippage = ₹0.40 × 1000 = ₹400.
Annualized across hundreds of trades, slippage can significantly reduce returns.
The Hidden Cost of Slippage
Most traders focus on brokerage and exchange fees, but slippage is the invisible cost that can erode profits quietly.
Impact on Profitability
- High-frequency traders lose edge if slippage exceeds expected spread.
- Scalpers with tight profit targets face direct losses.
- Long-term investors may see negligible impact, but cumulative costs still matter.
Impact on Strategy Backtesting
Many trading strategies look profitable on paper but fail in live markets because backtests ignore slippage and transaction costs.
At Lares Algotech, backtesting systems simulate realistic execution delays and slippage to give traders a true picture of expected returns.
Factors Influencing Slippage
Order Size: Larger orders have higher slippage risk.
Market Liquidity: Thinly traded assets slip more.
Volatility: Sudden news or events increase price gaps.
Order Type: Market orders > Stop orders > Limit orders (in slippage likelihood).
Execution Speed: Slow brokers or internet lag amplify the issue.
Lares Algotech’s ultra-low-latency infrastructure minimizes execution delays—ensuring you capture intended entry and exit levels accurately.
Slippage in Algo & High-Frequency Trading
Algorithmic traders face slippage on every micro-execution, making execution quality a top priority.
How Algorithms Handle Slippage
- Smart Order Routing: Splits large orders across multiple exchanges.
- TWAP/VWAP Algorithms: Execute gradually to match average market prices.
- Dynamic Liquidity Detection: Adjusts speed and volume based on live depth.
- Latency Arbitrage Prevention: Reduces price drift between signal and order.
Lares Algotech’s advanced trading systems integrate these controls to manage slippage effectively—especially in volatile or illiquid markets.
Real-World Example: How Slippage Impacts Intraday Traders
Imagine two intraday traders using the same scalping strategy:
| Trader A (Manual) | Trader B (Algo via Lares Algotech) | |
| Target profit per trade | ₹0.80 | ₹0.80 |
| Average slippage | ₹0.30 | ₹0.05 |
| Net gain per trade | ₹0.50 | ₹0.75 |
| Trades per day | 20 | 20 |
| Daily profit | ₹10 | ₹15 |
Over time, Lares Algotech’s precision execution leads to higher consistency and lower cost per trade.
Slippage During Major Economic Events
Events like Union Budgets, RBI policy announcements, or global rate decisions can cause sudden liquidity gaps.
Example:
- RBI unexpectedly hikes repo rate.
- Nifty futures drop 100 points instantly.
- Stop-loss orders convert to market orders and execute at worse levels—classic negative slippage.
That’s why Lares Algotech advises traders to:
- Reduce position size before announcements.
- Avoid placing large market orders.
- Use bracket orders or slippage-buffer algorithms.
Minimizing Slippage: Proven Techniques
Trade in Liquid Markets
Stick to instruments with tight bid-ask spreads.
Avoid High-Volatility Periods
Skip trading during news releases or opening/closing minutes.
Use Limit or Stop-Limit Orders
Control the price you accept instead of letting the market decide.
Deploy Smart Algos
Use AI-driven execution algorithms like those provided by Lares Algotech for optimal entry and exit.

- Smart Execution Algorithms
Together, these technologies reduce human delay, helping traders stay competitive even in volatile markets.
Measuring Slippage in Algorithmic Backtesting
For accurate backtesting, traders must simulate slippage realistically. Lares Algotech uses models based on:
Historical Bid-Ask Data
Order-Book Depth Analysis
Latency Simulation
Dynamic Volatility Adjustment
These simulations ensure that paper-strategy performance closely mirrors live-market behavior—bridging the gap between theory and reality.
Slippage vs Spread: The Difference
Many traders confuse slippage with spread, but they are distinct concepts.
| Parameter | Spread | Slippage |
| Definition | Difference between bid and ask prices. | Difference between expected and executed price. |
| Nature | Static (existing before trade). | Dynamic (occurs during execution). |
| Control | Controlled by market liquidity. | Controlled by execution timing and volatility. |
| Impact | Cost per trade. | Performance deviation. |
Understanding both helps traders price trades better and design more accurate strategies.
Positive Slippage – When It Works in Your Favor
Although rare, positive slippage can occur—especially in fast-falling or low-liquidity markets.
Example:
- You place a sell order at ₹250.
- Before execution, price falls to ₹250.40.
- You sell at a better rate, gaining ₹0.40 extra.
Lares Algotech’s adaptive routing system can sometimes capture such opportunities automatically, improving trade performance.
Slippage in Different Trading Styles
| Trading Style | Slippage Impact | Remarks |
| Scalping | Extremely High | Each tick matters; automation critical. |
| Intraday | Moderate | Manage with limit orders and liquidity filters. |
| Swing Trading | Low-Moderate | Smaller effect on overall returns. |
| Position Trading | Negligible | Long horizon offsets small deviations. |
| Algo/HFT | High Focus Area | Execution optimization vital. |
