Is There a Difference Between Volume and Open Interest?

Oct 14, 2022 By Susan Kelly

Options and futures contracts' liquidity and activity may be described by two major technical metrics: volume and open interest. The term "volume" describes the total number of contracts exchanged over a certain time frame, whereas "open interest" describes the number of contracts that have not yet been closed. Here, we take a closer look at these two indicators and provide some pointers on how to utilize them to interpret derivatives market behavior.

Volume

A stock market's volume indicates the frequency with which shares are traded. The volume statistic is used in the options market to determine the degree of activity for a specific contract and to keep track of the total number of purchased and sold options contracts during a given trading day.

The daily volume is the sum of all trades, whether they be opening or closing trades. Higher volume indicates that more people are buying or selling the underlying security. To some extent, volume is used by investors as a proxy for the magnitude of a price change.

Liquidity, or the number of buyers and sellers in the market, increases in tandem with trade volume, which is positive from a short-term trading standpoint.

Open Interest

"open interest" refers to the total number of open options and futures contracts owned by market participants. These positions have been initiated but have yet to be closed, expired, or exercised. Open interest falls when more contracts are closed out by buyers and sellers than were opened that day.

A trader must either take an opposite position or execute an option to close a position. Open interest rises when more contracts are opened than closed, either because buyers take on more long positions or sellers take on more short ones.

Consider that the ABC call option has no open interest. The next day, the investor initiates a new position by purchasing ten options contracts. Right now, there are ten people interested in buying this call option. Five contracts were closed, and ten were opened the next day, raising the open interest by five to fifteen.

Exceptions and Cautions

We then attribute various meanings to these instances using the volume and open interest metrics.

  • During an upswing, rising prices and rising open interest may indicate the entrance of fresh funds into the market (reflecting new positions). If long bets are driving the rise in open interest, this might indicate a bullish mood.
  • If, on the other hand, open interest falls even as prices rise during an upswing, this may be seen as money leaving the market and therefore be a negative indicator.
  • A spike in open interest and a decline in prices during a slump might indicate that short positions attract fresh capital. This scenario is gloomy since it fits with the current downward trend.

However, a drop in open interest alongside dropping prices in a downtrend is a negative indication since it may signal that holders are being compelled to liquidate their positions. Also, if this happens, a sales peak may be on the horizon.

The Option Chain: What Is It?

Security options are listed in an option chain or options matrix table. All of the listed calls and puts for a certain maturity date are shown in one place in an option chain, together with relevant information such as strike price, expiry date, volume, and price.

How Much Volume and Open Interest Does an Option Need?

Both strong volume and open interest are signs of a healthy options market with many willing buyers and sellers. Likewise, shifts in open interest and volume can attest to the authenticity of market sentiment. For instance, a strong option market is characterized by a rising price, growing volume, and open interest. In contrast, a weak market is characterized by a rising price, declining volume, and open interest.

What Does It Mean If Volume Exceeds Open Interest?

If an option has a large volume but low open interest, it may have a small secondary market and poor liquidity. A wider bid-ask spread or trouble finding a buyer might discourage a trader from trying to offload the option.

Can You Explain a Lot of Open Interest?

When there is a lot of "open interest" in a futures or options contract, many people actively trade that particular contract. Over time, an increase in open interest indicates that more investors are buying into the market. A gradual drop in open interest indicates that investors are unloading their holdings.

What Should You Know About Foreclosure Rights?
If a borrower stops making their mortgage payments, then the lender may foreclose on the loan and seize control of the property. When a borrower cannot pay monthly mortgage payments as agreed upon, the lender or association may use their foreclosure right and take possession of the property. Take the case of a homeowner who borrows $400,000 for a single-family residence and pays $2,600 monthly through mortgage payments. The buyer is given loan approval based on their salary and other financial details. A buyer's ability to make mortgage payments is contingent upon their continuing employment. If the buyer leaves their job and continues to fall behind on payments for an extended period, the bank may foreclose and sell the property.
