What Is Latency in Crypto? Everything You Need to Know

Timing is everything in the blockchain world. A delay of just two seconds can expose your assets to volatility and potential loss. For this reason, paying attention to latency in crypto is critical. The faster your transaction is processed, the safer your assets and the more profit you can potentially earn.

In this article, we’ll break down what latency in crypto really means, why it matters, how to measure it, the different types of latency, the types of hosting available, and the potential consequences high latency can have on your trading performance and profits.

What Is Latency in Crypto? 

Latency refers to the delay in data transfer or connecting to a network. Ideally, data should be processed instantly, but delays can still happen due to various factors, some of which are preventable, like poor internet connection or outdated devices, while others, such as long physical distances or server congestion, are outside your control.

The main reasons for latency are the distance between networks and server congestion. These are things you can’t really control. But sometimes, latency comes from issues you can fix, like using a low-quality device or having a weak internet connection that doesn’t meet the standard.

Why Is Latency Important in the Blockchain?

As mentioned earlier, crypto is highly volatile, just a two-second delay, and the value of an asset can shift. As a result, precise timing is important when conducting transactions. Even if the price change seems small, big investors know that even a one-penny difference can’t be ignored.

How to Measure Latency

Latency, or hold in data connection, is typically estimated in incredibly small units of duration. In the world of crypto trading, speed is everything, especially for those using automated trading systems where real-time data is key. There are three main time units used to measure latency: milliseconds (ms), microseconds (µs), and nanoseconds (ns).

• Milliseconds (ms)

Milliseconds (ms), or one-thousandth of a second, is the most commonly used unit. It’s generally fast enough for regular trading activities, like monitoring price movements and making manual decisions, where split-second reactions aren’t critical.

• Microseconds (µs)

Microseconds (µs), or one-millionth of a second, is a much smaller unit. It’s typically used in automated trading where immediate execution matters. Traders using bots or algorithms rely on this speed to respond instantly to market changes. The lower the latency, the quicker the system can react to volatility.

• Nanoseconds (ns)

Nanoseconds (ns), or one-billionth of a second, represent an even finer measurement. This level of precision is used in high-frequency trading (HFT), where even the tiniest edge in speed can make a significant difference in a highly competitive environment.

Reaching nanosecond-level latency requires top-tier infrastructure. This kind of speed is usually only possible for hedge funds or large financial institutions with fully optimized, high-end systems that are built specifically to gain a competitive edge in fast-paced markets.

Types of Latency

Understanding the types of latency is essential for traders. Besides identifying the causes of delay, it helps traders make informed choices about platforms, devices, and strategies to use. Latency isn’t just about having a fast internet connection, it also involves other factors, some of which can be prevented, while others cannot.

• Market Data Latency

Market data latency refers to the delay that occurs when market data is transmitted from an exchange to a trading platform. For example, when Bitcoin’s price changes slightly on an exchange, the updated data needs to be sent to users and the application.

If latency is high, the price information received won’t be accurate, which means traders are making decisions based on outdated data that can lead to missed opportunities or losses. In the trading world, such outdated information is essentially useless and offers no value to traders.

• Order Execution Latency

Order execution latency refers to the time it takes from the moment you click the buy or sell button until the order is processed and executed by the exchange system. The faster this process, the greater your chances of gaining profit, especially in fast-moving markets where timing can make or break a trade.

However, if latency is high and causes a delay in order execution, the price will likely change by the time the order goes through. When that happens, you’ve already missed the best momentum, and even a small shift can make a big difference in your final return.

• Network Latency

Network latency ensues due to pauses in signal transmission over the internet. This can be caused by your router, the quality of your internet connection, and the physical distance between you and the exchange server.

For example, if you’re in Indonesia but the exchange server is located in the United States, your signal has to travel thousands of miles to send the data, causing a delay in the process and affecting how quickly your transactions are executed.

• Software Latency

Software latency is a delay caused by the system or trading application you’re using. The program itself can contribute to transaction latency. For example, if there’s a bug or the trading algorithm isn’t efficient enough to process incoming market price data.

This can result in delayed information being displayed on the app, which then leads to delayed order execution. In the end, it’s the trader who has to bear the loss of potential profit, especially during high volatility when every second counts.

• Hardware Latency

Hardware latency is caused by the device you’re using, whether it’s a laptop, PC, or server. If your hardware is outdated or has below-standard specifications, it will slow down the data processing and affect your overall trading performance.

Even if your internet connection is fast, an old or underperforming device can still cause delays when making decisions or executing orders. That’s why it’s important to optimize both your hardware and internet connection to minimize unnecessary latency.

• Market Data Feed Latency

Market data feed latency is the time gap between a price update on the exchange and its arrival at traders. This delay can impact the accuracy and timeliness of the information traders rely on to make decisions.

For example, if there’s a large transaction that affects the market price, the updated data needs to be sent through the data feed system before reaching users. The faster this process happens, the more accurate and up-to-date the information traders receive.

• Market Latency

Market latency usually occurs when the market is crowded or experiencing high volatility. When many people are trading at the same time, the exchange system can slow down due to overloaded servers.

This can lead to delayed order execution and outdated data. Even if your system, device, and internet are fully optimized, a congested exchange server will still cause latency on your end, making it harder to respond accurately to fast market changes.

• Exchange Latency

Exchange latency measures how quickly transactions are handled by the exchange system. It relates to the internal performance of the exchange itself. The faster they can process orders and update prices, the lower the latency.

Exchanges typically have optimized infrastructure to minimize latency. However, not every exchange can afford such advanced systems. As a result, traders should consider the reliability and speed of an exchange’s technology before committing to it.

What Types of Hosting Are There?

In trading systems or crypto applications, latency speed is often influenced by the type of hosting used. Generally, there are two main options: self-hosted servers and cloud hosting services like AWS, each with its own advantages and trade-offs.

As the name suggests, self-hosted refers to having a personal server and managing it on your own. Since the server is customized and configured by yourself, the latency is usually lower, giving you greater control over performance and faster data processing.

Lower latency means you can connect and process data faster. You have full control over the technical system and server performance. However, you also need to handle everything on your own, from installation and maintenance to troubleshooting if any problem occurs. This requires sufficient knowledge and resources to keep everything running properly.

Cloud hosting, such as the one provided by AWS or similar services, offers more flexibility and efficiency. You don’t need to manage the hardware because everything is already handled by the cloud system. It’s also easier to scale the system up or down based on your needs, which helps when dealing with fluctuating traffic.

However, since the resources are shared with other users, the latency is generally higher. Still, the difference isn’t too significant, and cloud services remain reliable for various needs, offering a good balance between performance and convenience for most traders.

With that, the choice between self-hosted and cloud hosting depends on how much control you want, how ready you are to manage the server yourself, and how important latency is for your operations.

Why Is High Latency Bad for Traders?

In the crypto world, there is a type of trading called high-frequency trading (HFT) that requires computing speeds measured in microseconds to secure the best price. Even a small delay can change the original price right after you click. Because of crypto’s volatile nature, this delay can cause you to miss out on the highest profit opportunity.

Slippage

Slippage occurs when the executed price differs from the price you initially saw. For example, you want to buy a coin at $10, but due to data delay, the order gets executed at $10.50, and that small gap, repeated over time, can quietly eat into your trading profits.

At first glance, this difference might seem small. However, the more often you make transactions with delays like this, the greater your losses add up. You only discover the total result when you calculate all those transactions.

Arbitrage

Arbitrage is a trading method that takes advantage of price differences for the same asset across other exchange platforms. For example, if Bitcoin is cheaper on exchange X than on exchange Y, you can buy it on X and sell it on Y to make a profit.

However, if latency is high, this strategy becomes risky. Imagine the price on exchange X rises just as your transaction is completed, caused by delayed data. Instead of earning a profit, you could end up with a loss.

Real-Time Data

Traders in the crypto market rely heavily on real-time data to make fast and accurate decisions. Real-time data refers to information that is updated instantly and available without delay.

If latency is high, the data received by traders won’t be up to date. This can lead to poor decision-making, as the information being used is already outdated. Low latency is key to success in crypto trading.

Conclusion

In crypto trading, every millisecond matters. Latency, the delay in data updates or order execution, can cause outdated information, missed opportunities, and losses. Understanding different types of latency, from network delays to hardware and software issues, helps traders choose better platforms and optimize their setups to reduce risk.

Choosing the right infrastructure, whether self-hosted or cloud-based, also affects latency. While top exchanges invest in low-latency systems, not all can afford it. Minimizing latency is crucial for making timely decisions, protecting assets, and maximizing profits in the fast-moving crypto market.
