With over 560 million cryptocurrency users worldwide, understanding how the crypto market behaves is super important. Open interest is one such important metric which is used by many traders while trading crypto. Anyone who is crypto curious would have definitely seen this term on trading platforms or in crypto related news pieces.

In this blog we will break down what open interest means in crypto, how it is different from trading volume, how you can do crypto trading using open interest, and introduce you with tools like TransFi Wallet which can help you manage your crypto in a secure manner once you start trading. 

What is Open Interest in Crypto?

Let’s say you and your friend both mutually agree to bet on the price of Bitcoin - you think it will go up, and your friend thinks it will go down. Now if you think about this bet as a contract, and when it’s active, it adds to open interest.

So basically, open interest is the total number of active contracts (like bets) in crypto futures and options that haven’t been closed yet. As soon as they close, open interest goes down.
To sum it up, open interest in crypto shows the number of open “trading positions” that exist at a point of time.

Open Interest vs Volume in Crypto

People usually get confused between open interest and volume in crypto, as these terms sound similar, but in reality they mean very different things:

  • Volume means the number of trades that happened in a particular period of time.
  • Open interest means how many trades are still open right now at this particular time.

To make it easier, think of volume as a grocery store- it tells how many people went in and out of a store today. Whereas, open interest is how many people are still inside shopping.

Volume can go up and down all day, but open interest only changes when trades are opened or closed.

How to Use Open Interest in Crypto Trading?

Understanding open interest is more than just knowing a number. It’s about using that number to make smarter trading decisions. Let’s explore how this works in real crypto trading.

Crypto Derivatives Trading: Open Interest Explained

In crypto, open interest is most commonly used for trading derivatives like futures or options. These are financial contracts where traders bet on the future price of a coin like Bitcoin or Ethereum, instead of buying the actual coin.

Every time someone opens a long or short position in a crypto futures market, open interest increases. When they close that position, it decreases.

So in crypto derivatives trading, open interest helps you see how much money or how many positions are currently active in the market. More open interest usually means more traders are entering the game which can increase volatility and give stronger price signals.

For example,  if open interest on BTC futures jumps suddenly, it could mean that big players (like institutions or whales) are getting involved.

Interpreting Open Interest Data in Crypto

Now that you know the basics, you might be surprised to know that open interest can actually help you guess what traders might do next by observing some common patterns.

Here’s how open interest affects crypto price movements:

  • Price goes up + Open Interest goes up: More people are betting the price will keep rising (bullish signal).
  • Price goes down + Open Interest goes up: Traders may expect the price to fall more (bearish signal).
  • Price moves but Open Interest stays flat or drops: Traders might not be confident; the move may not last.

So, by watching open interest, you can get a sense of how strong a price trend really is. It’s like watching the crowd at a game—if more people are showing up and getting louder, something big is probably happening.

All the research, reading, analysing can seem a bit daunting sometimes, especially for people who are newbies to the whole crypto thing. To save your time & efforts there are many online tools & platforms that show open interest data. Here are some good open interest indicators & tools:

FAQs

  1. What does open interest tell you in crypto trading?

Open interest shows how many active contracts (like futures or options) are currently open and not yet settled. It helps traders understand how much money or interest is in the market. If open interest is rising, it means more traders are entering positions—which can signal a strong trend. If it’s falling, traders may be closing out, and a trend could be weakening.

  1. How does open interest affects crypto price movements?
