What Does Open Interest Mean In Options


What Does The Increase/decrease In Open Interest Imply

What Open Interest Tells Us About Trends

An increase in Open Interest means that new money is flowing in the market. And it generally indicates that the present trend is expected to continue.

A decline is an open interest usually implies, that the current trend is expected to halt and we could see a reversal in the market. To know the current open Interest, we just need to know the total from the buyer or seller side and not both.

Options Volume And Open Interest: Why You Need To Understand Them

Options volume and price movements in the stock market are reflections of decisions to purchase or sell by millions of options investors. However, the price isnt the only piece of data successful investors monitor. Open interest and options volume are also important numbers to keep on eye on when buying and selling options. Understanding each of these numbers help investors make better-informed decisions when investing.

Key Takeaways

  • Options volume describes the activity level and liquidity of contracts in the options market.
  • Options volume refers to how many trades are completed making it an essential measurement of interest and strength of an option
  • Open interest refers to the number of options contracts held by investors and traders in active positions, or ready to be traded.

Key Difference Between Volume And Open Interest

Investors can trade the same options contract multiple times . When a new contract is traded, open interest increases. Open interest can increase or decrease before expiration.

The difference between open interest and volume can be confusing. As a stock trader, you only have a single measure of liquidity and activity: volume.

Like stocks, options contract volume displays that dayâs activity, whereas open interest is the total number of contracts outstanding.

Options traders must consider both volume and open interest because the two data points tell different stories.

Whether To Buy Options With High Or Low Open Interest

High open interest is important because it shows signs of liquidity. Higher liquidity generally means that you can close a position whenever you want to at a reasonable price.

Likewise, the spread between the bid and ask prices is also low because there are lots of interested buyers and sellers. Lower spread means that you can enter the market easily without worrying about the high asking price. As a rule of thumb, bid-ask spread within 10% of the asking price is a sign of solid activity.

Because of these benefits, at-the-money options typically have the highest open interest. Traders are generally more interested in an at-the-money option because the options strike price is very close to the price of the underlying asset. On the other hand, OTM options often see less trading activity because the strike price is farther from the actual price of the underlying asset.

While a high open interest is beneficial in many instances, it doesnt mean that you shouldnt buy an option with low open interest. As discussed, most OTM options will have a low open interest.

Therefore, if you intend to hold a crypto option until its expiration date, low open interest doesnt really matter. Similarly, if youre sure that the long-term movement of the underlying asset will be in your favor, low open interest need not be a deciding factor in your decision-making process.

Why High Open Interest Is Good

High open interest typically means it’s easier to trade the option because there are more market participants actively trading that contract.

The increased activity in the contract leads to better liquidity, so orders fill faster with tighter bid-ask spreads.

Illiquid options or stocks can be incredibly difficult to exit at a reasonable price, so a key ââ item is a minimum amount of open interest.

Higher open interest doesnât necessarily mean smart traders are active in the contract. Higher open interest simply means there is higher activity or interest in that particular strike price.

Types Of Options & Value Of A Contract

  • : It is similar to buying shares of stock. It gives the holder of the option the right to buy shares at a specified price until a specified date in the future.
  • Put option: It gives the holder of the option the right to sell shares at a specified price up until a set date in the future.

If youve traded stock options in the past, its important to distinguish between a stock option contract and a crypto option contract. When you buy a stock option, youre controlling 100 percent of the shares of the stock.

However, the number of underlying assets may be different when trading a crypto option. For instance, one Bitcoin option contract represents the right to buy or sell one Bitcoin. You can also buy 0.1 Bitcoin options contracts.

What Is The Minimum Volume Or Open Interest For Options Trading

There is no set minimum open interest for options trading. However, exchanges may require a certain level of open interest to list an option contract. For example, the Chicago Board Options Exchange requires that at least 500 contracts must be traded on each day for an option to remain listed.

It is essential to have a daily trading volume and open interest of at least 10-50 times the amount of contracts a trader would be looking to buy. But the higher, the better because of the points listed previously.

In fact, options are attractive because they allow traders to gain substantial benefits even when risking only a small amount as compared to crypto futures contracts or perpetual swaps.

Open Interest Vs Volume

Volume & Open Interest Explained | Options Trading Concepts

Trading volume and Open Interest are both significant in their ways, and both are indicators for liquidity and market activities. Open interest is more specific to the number of contracts in options and futures contracts that are active or not settled for an asset at a given point in time. On the other hand, volume is more specific to particular securities that are traded in a specific period. Both are considered important metrics or market indicators to identifying the volatility or dynamic market conditions. They both also directly reflect the liquidity in the market for a particular security, and the market exchange calculates the changes in value, and the total calculations are done at the end of each market day.

Open interest increases and decreases dynamically it increases when new contracts are added and decreases when positions in existing contracts are closed by buyers and sellers. This is significant data and, when incorporated with trading volume, can help in the wise analysis of market trends. The volume trading metric measures the trade for a specific period and specific security, which can give the investor insights about a particular security. In contrast, the open interest gives the overall picture of active interest in particular security or data.

How To Calculate Open Interest

Each trade completed on the exchange has an impact upon the level of open interest for that day.

For example, if both parties to the trade are initiating a new position , open interest will increase by one contract.

If both traders are closing an existing or old position open interest will decline by one contract.

The third and final possibility is one old trader passing off his position to a new trader . In this case the open interest will not change.

Open Interest and Volume

Open interest and volume are the two important concepts in the futures market. Traders look at both to predict trends.

Lets discuss them one by one. Though both OI and volume are quite similar, which often confuses new traders, they are not the same.

OI represents the number of open contracts in the futures market, in possession of individual buyers and sellers.

Now for the futures market, for every contract sold, there should be a buyer. So, the number of total contracts transacted in the day remains balanced. Volume refers to the total number of contracts executed during the day. So, if one contract is sold and bought, the volume goes up by one .

At the beginning of the day, the volume is set to zero. Hence, you get a clear picture of the number of contracts exchanged hands during the trading hours. Open interest is not as discreet as volume. The value of open interest may remain unchanged or change depending on the number of traders entering or exiting the trade.

Why Open Interest And Options Volume Is Important

Volume and open interest are the two main variables that indicate the potential movement of an option. If youre new to trading crypto options, keep a close eye on these two variables because they may be the only thing you need to make a good decision.

Open interest is the number of outstanding contracts that have yet to settle. If youve bought a contract and youre holding onto it, thats an example of open interest. Likewise, volume is the number of contracts being exchanged on a given day by buyers and sellers. The number of contracts bought and sold is the trading volume.

Volume and open interest are reliable indicators because they reflect the overall sentiment of the crypto market. There are two scenarios when interpreting volume and open interest:

  • Scenario 1: Whenever the volume and open interest are high, it means that the price of the contract is likely to move in the direction of the market sentiment. Its not an overstatement to suggest that high volume and open interest give momentum to the contract, which is necessary to move the price in the right direction.
  • Scenario 2: Option contracts that have low volume and low open interest are likely to take longer to reach the desired price.

This doesnt mean you should ignore contracts that have low volume and open interest. Experienced traders understand that options that are out of the money or that have plenty of time till expiration usually have low volume and open interest.

High Volume Versus Open Interest Example

In the example below, you can see more contracts bought on Facebook than open interest options for the trading day. The amount of volume option was 4766, while the open interest was 1841. This is a multiple of over two.

This means that any new money market participants buying the option are paying a premium at this bid price because of the lack of buyers and sellers. This could also be an indication that theres an anticipated price movement coming. Many traders will look at this particular call option with a bullish bias on Facebook.

Open Interest In Options

As we were talking about Abhishek Upmanyus show previously, the number of tickets that were available in the beginning represents the open interest. This means that the positions which were opened to be filled.

Slowly, when the seats started filling, the vacant ones decreased in number. This is what an open interest in options means.

Open interest is the number of outstanding contracts in the market. Every time a new buyer or seller enters the market, there is a change in the open interest in options.

The high and low open interest option says a lot about the current and upcoming trends of the market.

It is therefore very important to understand the analysis of open interest as well.

Difference Between Open Interest And Volumes

There is generally a common misconception that both OI and volumes mean one and the same thing. However, they are two different concepts, giving out two different sets of data. But, both the data can be used in conjuncture. Let us understand the concept of Open Interest with the help of an example.

Say, there are five traders trading the Nifty futures contract. Let us understand, as to how their trading has an impact on the open interest and its calculation.

On Monday: A buys 20 Nifty futures contract and B also buys 10 Nifty futures contract. While C sells 30 Nifty futures contract in the market. Therefore, we have a buying activity of 30 futures contracts and a selling activity of 30 futures contracts. Hence, the total Open Interest is 30.

50 50S

If we carefully analyze and look at the table above, it gives us a fair sense that open interest is eventually a zero-sum game. If we add all the longs and subtract them with all the shorts in the market. The end result is eventually zero.

Now, if we look at the snapshot above , it is the data showing the shares with the highest change in the open interest for the day. With the change in the open interest, the share price has also gone up and which is usually an indication that the buying momentum is expected to continue in these ten shares.

Using Open Interest In Options Trading

A number of options traders make the mistake of ignoring open interest, assuming that it isnt really that relevant. Conversely, a number of traders over value the importance of it, believing it’s the sole indicator of the liquidity of the contract. The truth is actually somewhere in the middle. It’s certainly relevant, but it’s only one of three indicators of liquidity.

The liquidity of options contracts is very important to traders. Liquidity gives you an idea of how easily specific options can be bought and sold at the market price. Highly liquid ones are generally easy to buy and sell, and orders will be filled quickly. Ones with low liquidity, on the other hand, aren’t necessarily that easy to trade. Ideally, you want to be trading ones with a high liquidity to ensure that you can enter and exit positions with relative ease.

Options contracts that have a high open interest tend to also have high liquidity, but as mentioned above, there are other factors to consider too. Those other factors are the trading volume of an option and its bid ask spread. High trading volume of an option generally indicates high liquidity. Ab small bid does as well. Only by looking at all the relevant criteria is it possible to get a reasonably accurate idea of how to determine how liquid an options contract is.

How Open Interest Changes

Options Trading: What Does Open Interest Mean

The change in OI takes place when a trade is initiated between two parties. Consequently, the open interest increases, decreases or remains the same. Let us take an example and understand how open interest changes.

  • Suppose a new buyer takes a position in GMR Infra. by purchasing from a new seller. In this case, the OI will increase by one contract.
  • Suppose an old buyer and an old seller decide to close their positions in GMR Infra. This will lead to a decline in OI by one contract.
  • Suppose an old trader passes off his position in GMR Infra to a new trader, in such case the OI will not change.

Change in open interest gives an indication in relation to the movement in the price of the stock. Therefore, let us understand such indications.

What Change in Open Interest Indicates ?

For traders, open interest is of tremendous importance. To repeat, change in OI helps to understand the movement of stock price. For example, if the OI is increasing, it means the flow of money in the market or stock is increasing. Therefore, it suggests that the current trend in the price of stock i.e. upward, downward or sideways shall continue. On the other hand, if the OIis decreasing, it means that the current trend in stock price is over because the market is liquidating.

Even though open interest is the indicator of movement in the stock price. However, the investor should not always rely on it blindly.
