Introduction
In modern trading, understanding tick size is essential for building profitable and risk-aware strategies. Tick size, the smallest possible price increment by which an asset can move, influences liquidity, volatility, and order book dynamics. For traders—whether retail, institutional, or algorithmic—knowing how to use tick size in strategy can make the difference between consistent profits and costly mistakes.
This article provides a complete breakdown of tick size applications in strategy design. We’ll explore how it impacts order execution, liquidity management, and market efficiency, while also showing real-world strategy examples. Drawing from both academic research and hands-on trading experience, we’ll compare multiple methods for integrating tick size into trading approaches and highlight the best practices finance professionals use today.
What Is Tick Size?
Definition
Tick size is the minimum price change allowed for a given financial instrument. For example, in U.S. equities, the tick size is typically $0.01, while futures contracts or forex pairs have different increments depending on the exchange rules.
Why Tick Size Matters
Tick size determines:
- The spread between bid and ask prices.
- The ease of placing limit orders near best quotes.
- Market liquidity and volatility dynamics.
This explains why tick size matters in trading: it is directly tied to execution efficiency, slippage, and profit margins.
Tick size affects spreads and liquidity in order book trading.
How to Use Tick Size in Strategy
Strategy 1: Spread and Market Making
Market makers profit from the difference between bid and ask spreads. A larger tick size often increases spreads, giving market makers more room to earn per trade.
Advantages:
- Potential for higher profits per trade.
- Easier to manage inventory risk with wider spreads.
Disadvantages:
- Larger tick size may discourage liquidity providers if spreads become too wide.
- Retail traders may face higher transaction costs.
Strategy 2: Scalping and High-Frequency Trading (HFT)
For scalpers and HFT traders, small price increments can be exploited for rapid, frequent gains. Here, how does tick size affect liquidity becomes crucial. A smaller tick size generally improves liquidity but also increases competition, squeezing margins.
Advantages:
- More precise entry and exit points.
- Higher liquidity in small-tick-size markets.
Disadvantages:
- Increased competition among algorithms.
- Lower average profit per trade.
Recommendation: For day traders and scalpers, small tick size environments provide better opportunities for fast execution, while market makers may prefer larger tick size assets.
Scalping strategies benefit from smaller tick sizes, enabling tighter entries and exits.
Comparing Tick Size Effects Across Asset Classes
Equities
U.S. stocks typically trade at $0.01 tick increments. However, research shows that reducing tick size further can improve liquidity but may also increase quote flickering, making execution harder for slower traders.
Futures
Futures contracts often have standardized tick sizes, such as 0.25 index points for S&P 500 E-mini futures. Futures traders must adapt their position sizing and stop-loss levels based on tick value, since each tick represents a fixed monetary amount.
Forex and Crypto
Forex pairs use fractional pips (0.0001 or smaller) as tick size, while crypto exchanges often have custom-defined tick sizes. These ultra-small increments allow flexible trading but can also lead to excessive noise.
Options
Options markets use variable tick sizes depending on the strike price and premium. Wider tick sizes in options trading can increase transaction costs but also provide better profit margins for market makers.
Tick Size and Risk Management
Stop-Loss Placement
Stop-loss orders should align with tick increments. Placing a stop exactly at a common tick level may lead to premature execution due to clustering.
Position Sizing
Futures traders especially must calculate risk per tick since each move has a predefined monetary impact. Learning how to calculate tick size helps traders align position sizing with account risk.
Volatility Impact
A smaller tick size tends to reduce volatility by tightening spreads, while larger tick sizes may amplify intraday swings. This explains how does tick size impact volatility and why regulators occasionally adjust it.
Proper tick size considerations help traders align stop-loss and position sizing with market structure.
Real-World Example: Tick Size Strategy in Futures
- Select a futures contract (e.g., crude oil with \(0.01 tick size = \)10 value per tick).
- Identify average daily volatility (e.g., $1 = 100 ticks).
- Design a strategy with 10-tick stop-loss and 20-tick take-profit.
- Adjust position size to risk no more than 1% of account equity per trade.
- Backtest the system to evaluate performance in different volatility environments.
Insight: A larger tick value increases risk per trade, requiring tighter risk control.
Best Practices for Using Tick Size in Strategy
- Always confirm tick size before designing entry/exit rules.
- Avoid placing orders at predictable tick levels to reduce slippage.
- Adjust strategy depending on whether you’re scalping, swing trading, or market making.
- Test strategies in both simulated and live environments to observe liquidity differences.
FAQ: Tick Size in Trading Strategies
1. How do I know the tick size for a specific asset?
You can check exchange websites or broker platforms. This is where to find tick size information, as most exchanges publish official tick size tables.
2. Should retail traders care about tick size?
Yes. Even though institutional traders face greater liquidity constraints, retail traders must understand tick size to optimize order placement, stop-loss positioning, and minimize trading costs.
3. Can tick size changes affect my strategy performance?
Absolutely. Regulators sometimes adjust tick sizes to improve market efficiency. For example, increasing tick size can widen spreads, which may harm scalpers but benefit market makers.
4. Is tick size more important in futures or equities?
It’s critical in both, but especially in futures because each tick represents a fixed dollar value, directly impacting profit and loss calculations.
Conclusion
Mastering how to use tick size in strategy is a critical skill for traders of all levels. Tick size influences spreads, liquidity, volatility, and execution quality. From market making to scalping, futures to forex, each asset class requires a unique adaptation of tick size considerations.
As you develop strategies, always incorporate tick size into your risk management and order placement. By doing so, you’ll improve trade precision, reduce slippage, and adapt more effectively to evolving market structures.
