Liquidity in crypto trading: Why it matters and how to spot the best conditions

Liquidity is the lifeblood of efficient crypto trading. It determines how quickly and smoothly assets can be bought or sold at stable prices. And yet, many traders tend to overlook liquidity’s role in reducing slippage, tightening spreads and improving execution speed — all of which directly impact profitability.

Bybit has made significant strides in improving liquidity across its trading pairs, ensuring that traders benefit from faster execution, better pricing and minimal market impact across both spot and derivatives markets. This article will explore what liquidity is, why it matters, how to measure it — and why Bybit offers one of the most liquid trading environments in the industry.

Key Takeaways:

• Liquidity is the ability to buy or sell an asset quickly, without causing significant price fluctuations.

• A liquid market has a deep order book with large quantities of buy and sell orders spread across multiple price levels. When a trader places a large order, it’s absorbed by the existing orders, without drastically moving the market price.

• An illiquid market has fewer participants and a shallower order book, leading to greater price volatility and higher execution costs.

What Is liquidity?

Liquidity is the ability to buy or sell an asset quickly, without causing significant price fluctuations. In crypto trading, liquidity is determined by trading volume, order book depth and market participation. A highly liquid market ensures tighter spreads, faster order execution and reduced slippage, providing a more stable and efficient trading experience.

How does liquidity work?

Liquidity functions through market supply and demand. When many buyers and sellers actively place orders, transactions occur swiftly and price movements remain stable. Conversely, a lack of liquidity can lead to price gaps, delays and higher trading costs.

A deep order book is key to strong liquidity, with large quantities of buy and sell orders spread across multiple price levels. This means that when a trader places a large order, it’s absorbed by the existing orders, without drastically moving the market price. In contrast, an illiquid market has fewer participants and a shallower order book, so that a single order for an asset could drastically shift its price. This leads to greater price volatility and higher execution costs.

Market makers play a crucial role in maintaining liquidity by continually placing buy and sell orders. By providing a steady flow of orders, they help stabilize prices and narrow the bid-ask spread, ensuring smoother trading conditions for all participants.

In crypto trading, liquidity also varies between spot markets and derivatives markets. Spot liquidity is reflected in lower spreads, meaning traders can buy or sell assets at more competitive prices. In contrast, lower slippage is the key measure in derivatives trading.

Why liquidity is essential for traders

Liquidity has an impact on every aspect of trading, from execution speed to profitability. The following considerations make liquidity a key factor for traders.

Lower trading costs and tighter spreads

A tighter bid-ask spread ensures traders enter and exit trades at fairer prices. This is especially beneficial for scalpers and high-frequency traders who rely on small price movements for profits.

Minimal slippage and better price stability

Liquidity determines the degree to which an order affects price levels. In a highly liquid market, a $100,000 trade might move an asset’s price by only a fraction of a percent, while in an illiquid market, the same trade could cause a sharp price swing.

Faster and more reliable order execution

Liquidity allows traders to execute orders almost instantly at the expected price. In contrast, low-liquidity conditions may mean that, due to market fluctuations, orders will take longer to fill, or may execute at unfavorable prices.

Market resilience during volatility

During sudden price movements, a deep order book absorbs large trades, preventing extreme spikes or crashes. This is crucial for maintaining price stability in volatile markets: traders can execute strategies with greater confidence, knowing that price fluctuations will be more controlled.

How to identify and measure liquidity in crypto trading

While many traders assume liquidity is measured simply by trading volume, a deeper analysis is required to assess true liquidity conditions. The following section explains how traders can evaluate liquidity effectively.

Order book depth

A deeper order book means that multiple buy and sell orders exist across different price levels, supporting efficient trade execution with minimal price movement This is a strong indicator of liquidity, since it reflects a market’s ability to handle both small and large orders without sudden price fluctuations. 

For example, the ETH/USDT pair on Bybit has consistently shown strong order book depth, with the top three bid and ask levels holding significantly higher quantities as compared to other platforms. This enables smoother execution for all traders, from retail investors to institutions. 

Market impact of large orders

A true test of liquidity is the degree to which the market price moves when executing a large order. In a highly liquid market, trades are absorbed across multiple levels, ensuring minimal slippage and price disruption. 

Traders can simulate a large market order by entering a significant trade volume and observing how much the price shifts before execution. A market order that significantly changes the last traded price suggests lower liquidity and potential inefficiencies in trade execution. 

For example, in order to move an asset’s price from $1,877.64 to $1877.66 on Bybit, you’ll need to buy 57.02856 + 168.67890 + 26.21569. Likewise, in order to move the price from $1,877.63 to $1,877.60, you’ll need to sell 114.28408 + 16.35036 + 17.30490.

Order absorption

Order absorption measures how well a market handles large trades without causing price spikes or slippage. A highly liquid market has deeper buy and sell walls, allowing it to process large transactions smoothly.

Here’s an example: For Bybit’s ETH/USDT pair, large trades require consuming multiple price levels before affecting the last traded price. This ensures stability even during high trading volumes. A trader purchasing 30 ETH only absorbs Level 1 and Level 2 sell orders, whereas on lower-liquidity platforms, multiple levels would be affected, increasing price volatility.

This high order absorption capacity is vital for traders executing large transactions, ensuring consistent execution quality across all market conditions.

Bid-ask spread

The bid-ask spread represents the difference between the highest bid price (what buyers are willing to pay) and the lowest ask price (what sellers are willing to accept). A narrower spread indicates stronger liquidity, because it means there are many active buyers and sellers competing for the best prices. Conversely, a wider spread suggests a more illiquid market, leading to higher trading costs and greater price fluctuations.

How to compare liquidity

Compare order book depth

The first consideration is to compare the order book depths between different exchanges. Exchanges with higher quantities at each price level (for both bid and ask) suggest higher liquidity.

Calculate the market impact and compare

Step 1: Identify the initial market price

• Check the current best bid/ask price before placing a market order.

• For example, if ETH/USDT’s best ask price is $3,000, this is your initial market price.

Step 2: Simulate a market order (without executing it)

• Input a large order (e.g., 100,000 USDT) and observe how much of the order book is consumed.

• The final execution price is the average price for all filled portions of the order.

Step 3: Calculate the final execution price

• If the order consumes multiple price levels, determine the weighted average price (WAP).

• For example:

• 30,000 USDT filled at $3,000

• 40,000 USDT filled at $3,002

• 30,000 USDT filled at $3,005

• Final execution price = [(30,000 × $3,000) + (40,000 × $3,002) + (30,000 × $3,005)] / 100,000 = $3,002.10

Step 4: Calculate the market impact

• Market impact = [(Final execution price − Initial market price) / Initial market price] × 1

Step 5: Compare the market impact between exchanges.
