In the fast-evolving world of cryptocurrency trading, even the smallest technical details can have a significant impact on market behavior, liquidity, and trader profitability. One such critical yet often overlooked parameter is tick size—the minimum price increment at which a trading instrument can move. This article explores the concept of tick size, its influence on market participants, and how different exchanges approach this foundational aspect of order book mechanics.
Whether you're a seasoned trader or new to digital asset markets, understanding tick size helps reveal how exchanges shape trading dynamics behind the scenes.
What Is Tick Size?
Tick size, also known as "minimum price increment," defines the smallest possible change in the price of a financial instrument. In traditional markets—like stocks or commodities—tick sizes are often standardized based on regulatory frameworks and market conventions. For example, stock prices may move in increments of $0.01.
In cryptocurrency trading, however, tick sizes are determined by individual exchanges and vary significantly across platforms and assets. Unlike fiat-based systems that follow payment habits (e.g., cents or fractions thereof), cryptocurrencies were designed with high precision in mind due to their potential for exponential value growth. This allows for many decimal places, but exchanges must still define practical tick sizes for efficient trading.

The Strategic Role of Tick Size in Market Liquidity
At its core, tick size acts as a lever that exchanges use to balance the interests of two key groups: liquidity providers (makers) and liquidity takers (takers).
Trading venues typically follow a price-time priority model: orders are filled first by best price, then by time of submission. Within this framework, tick size directly affects how these participants interact:
Larger Tick Sizes: Advantages for Market Makers
When tick size is relatively large (e.g., 0.5 USD), competition among market makers tends to shift from price-based to time-based. Since small price improvements aren't feasible, makers cluster around key price levels, waiting for takers to execute against them.
This setup benefits market makers, who earn wider spreads per trade. However, it also means takers (speculators or institutional traders) must pay a higher implicit cost—approximately half the spread—to get immediate execution.
In markets with large tick sizes, liquidity is more concentrated, enabling larger orders to be filled efficiently despite higher per-trade costs.
Smaller Tick Sizes: Favors Liquidity Takers
Conversely, when tick sizes are small (e.g., 0.1 or lower), market makers compete aggressively by placing quotes just slightly better than rivals—by one tick. This drives spreads tighter and distributes liquidity across multiple price levels.
While this improves execution quality for takers, it compresses maker profits. If tick sizes become too small, the reward for providing liquidity may not justify the risk, especially in volatile conditions.
There’s a delicate balance: too much competition among makers can erode their margins, ultimately discouraging market-making activity and reducing overall liquidity.
Thus, larger tick sizes generally favor market makers, while smaller tick sizes benefit traders seeking tight spreads and low slippage.
How Major Exchanges Approach Tick Size Design
Different exchanges adopt distinct philosophies when setting tick sizes, reflecting their target user base and liquidity strategies.
A Leading B-Tier Exchange: Optimizing for Liquidity
One prominent exchange starting with "B" sets its BTC tick size at 0.5, a relatively generous increment in today’s market. Combined with a robust maker rebate program, this design incentivizes sustained market-making activity.
The result? Deep order books and strong liquidity. While traders pay a higher nominal cost per trade due to the larger tick, they gain access to superior execution certainty—especially valuable for large orders.
This model demonstrates that high liquidity can offset less granular pricing, making it attractive for institutional and high-volume traders.
An F-Named Platform: Integrating Ecosystem Incentives
Another major exchange beginning with "F" takes a broader approach. While its tick size structure supports competitive pricing, it introduces complexity through indirect rebates via its native token (FT).
This creates an additional layer of incentive alignment—but also dependency on tokenomics. Changes in the platform token's volatility or demand can indirectly affect maker profitability and thus liquidity provision.
It illustrates how non-price factors—such as reward mechanisms and trader composition—can influence market health as much as tick size itself.
A Notable O-Lettered Exchange: Precision Without Incentives
An exchange starting with "O" uses highly granular tick sizes—displayed up to four decimal places—based on the inherent precision of crypto assets.
However, without meaningful fee rebates or liquidity incentives, few professional makers participate actively. As a result, despite apparent pricing accuracy, actual market depth remains shallow.
This case highlights a crucial insight: fine-grained tick size alone does not guarantee good liquidity. Without proper economic incentives, market makers have little reason to commit capital.
Bybit’s Balanced Approach to Tick Size and Liquidity
Bybit stands out by combining insights from traditional finance with the unique characteristics of digital assets. It adopts a minimum tick size of 0.5 for major contracts—a deliberate choice that supports sustainable market-making.
To further enhance liquidity:
- Bybit offers ultra-low trading fees
- Implements liquidity rewards programs to encourage maker participation
This dual strategy ensures that:
- Market makers earn sufficient returns to justify risk
- Traders enjoy reliable depth and minimal slippage
The outcome is a balanced ecosystem where both makers and takers thrive—a hallmark of mature trading environments.

Frequently Asked Questions (FAQ)
Q: Does a smaller tick size always mean better pricing?
A: Not necessarily. While smaller ticks allow finer price granularity and tighter spreads, they can reduce maker profitability. Without sufficient incentives, this may lead to thinner overall liquidity.
Q: Why do some exchanges use larger tick sizes?
A: Larger tick sizes increase potential spread earnings for market makers, encouraging them to post consistent bids and offers. This can lead to deeper order books and better execution for large trades.
Q: Can tick size affect my trading costs?
A: Yes. A larger tick means wider spreads, increasing the cost for takers. Conversely, very small ticks may reduce visible spread but could decrease available liquidity if makers pull back.
Q: How do rebates influence the effectiveness of tick size?
A: Fee rebates amplify the attractiveness of a given tick structure. Even with moderate ticks, generous maker incentives can draw significant liquidity—proving that economic design matters beyond just technical parameters.
Q: Should retail traders care about tick size?
A: Absolutely. Tick size influences slippage, fill quality, and available order book depth—all of which impact real-world trading outcomes, especially during volatile periods.
Final Thoughts: Tick Size as a Market-Shaping Tool
Tick size is far more than a technical detail—it's a strategic instrument that shapes trading behavior, influences liquidity distribution, and determines the balance of power between makers and takers.
Exchanges like Bybit demonstrate that optimal design involves more than just choosing a number—it requires aligning pricing structure with incentive models to create resilient markets.
As crypto markets mature, expect greater sophistication in how platforms engineer these micro-structural elements to serve diverse user needs—from high-frequency traders to long-term investors.
