Understanding Open Interest
Volume and open interest are related concepts. Volume accounts for all contracts that have been traded in a given period, while open interest considers the total number of open positions held by market participants at any given time. Regardless of long or short positions, open interest adds up all opened trades and subtracts the trades that have been closed on Binance Futures.
Let’s consider a scenario where John, Alice, and Bob open a position in BTCBUSD Perpetual Futures Contracts at the same time that Sam closes his position.. Table 1 shows how open interest changes as a result of these traders’ activities.
Table 1 - Changes in open interest as a result of trading activity
As shown in the table above, open interest increased from 3 to 15 as traders open new positions, and declined as existing positions were closed. This illustrates how open interest changes based on the number of daily open contracts.
Why Open Interest Matters
In traditional futures markets, traders closely monitor changes in open interest as an indicator to determine market sentiment and the strength behind price trends.
Open interest indicates capital flowing in and out of the market. As capital flows into a futures contract, open interest increases. Conversely, as capital flows out of the derivatives markets, open interest declines. For this reason, increasing open interest is often considered as one of the many factors that can serve as confirmation of a bull market, whereas decreasing open interest signals a bear market.
Traders usually track the changes in price, volume, and open interest to analyze the prevailing market sentiment. Table 2 shows an interpretation of market behavior as a result of these fluctuations.

Open interest is an important signal of market behavior and may provide clues to market direction. Traders often incorporate these factors into their analysis of price trends and momentum.
