When trading digital assets, it's common to monitor their current and historical prices. Many trading platforms prominently display the price change percentage for each cryptocurrency to assist users in making informed decisions.
Among the most widely used metrics for comparing current and past prices is the "24-hour change." While different platforms may use slightly varied labels like "price change" or simply "change," the underlying meaning and calculation method remain fundamentally similar.
Let's explore what this indicator represents and how it is computed.
Understanding the Calculation Benchmark
Before interpreting price change data, it’s essential to understand the benchmark used for calculation. Most trading platforms provide explanations of their metrics on their websites. If such information isn’t readily available, users can often contact customer support for clarification.
For instance, some platforms calculate changes based on the most recent 24-hour period, while others might use a fixed starting point, such as midnight Beijing Time. Various international exchanges may adopt different reference times based on their operational preferences.
Since cryptocurrency markets operate 24/7, calculating price changes based on the preceding 24 hours offers stronger real-time relevance. This approach is considered more rational and is adopted by the majority of platforms worldwide. It eliminates timezone dependencies and aligns with global standards, making it convenient for users across different regions.
Methods for Calculating Price Changes
Due to differing benchmarks, the historical price data used to compute the change percentage can vary significantly.
Let’s first examine the method for calculating changes based on the most recent 24-hour period. Suppose it is currently 12:00 PM on November 19th, and the price of a specific digital asset is $23. If the price at 12:00 PM on November 18th was $25, the percentage change would be calculated as follows:
($23 – $25) ÷ $25 = -8%
This would be displayed as a -8% change or an 8% decrease.
Alternatively, if the platform uses a fixed daily starting point—such as midnight Beijing Time—the calculation would involve subtracting the price at that time from the current price, dividing the result by the starting price, and multiplying by 100 to get the percentage change. The same logic applies to any other fixed time benchmark.
Regardless of the method, the core formula remains consistent:
(Current Price – Previous Price) ÷ Previous Price × 100%
This straightforward calculation helps traders quickly gauge market movements.
Interpreting and Applying the Data
It’s important to note that price change percentages may differ across platforms due to variations in calculation benchmarks and slight differences in asset pricing on different exchanges.
As a trader, being aware of these discrepancies ensures you accurately interpret data and avoid misunderstandings. Whether you are a day trader or a long-term investor, understanding how these values are derived empowers you to make better-informed decisions.

Frequently Asked Questions
What does a negative percentage change indicate?
A negative value signifies a price decrease over the selected period. For example, a -5% change means the asset’s value has dropped by 5% compared to the earlier price.
Why do different platforms show different change percentages for the same asset?
Variations arise from differences in calculation benchmarks—such as the chosen time interval—and minor pricing disparities between exchanges due to liquidity and trading volume differences.
Can I use the 24-hour change to predict future prices?
While historical performance provides insight, it is not a guaranteed predictor of future movement. Market volatility, news events, and broader economic factors all influence price directions.
How frequently is the price change updated?
Most platforms update this metric in real-time, reflecting the most recent market data available to users.
Is the calculation method the same for all digital assets?
Yes, the formula remains consistent across different cryptocurrencies and tokens. However, the chosen benchmark timeframe may vary by platform.
What is the difference between price change and price return?
Price change refers to the net difference over a period, while return often includes additional factors like dividends or staking rewards, though these are less common in pure trading contexts.
Conclusion
Understanding how digital asset price changes are calculated is fundamental for every trader. By recognizing that platforms may use different reference points and computation standards, you can better interpret the data presented to you.
Always verify the calculation methodology used by your preferred platform and ensure you factor in these nuances when making trading decisions. With this knowledge, you can navigate cryptocurrency markets more confidently and effectively.
Remember, while metrics like the 24-hour change are useful indicators, they should be part of a broader analysis strategy that includes market trends, technical analysis, and risk assessment.
