Any experienced trader knows that the stock market is a complex, dynamic system of trading and investments. This complexity is what drives the need for options trading. In order for traders to make informed decisions about their trades, they need to understand all of the factors at play in the market. One of these factors is open interest.

The idea of open interest options is an important one. It is a measure of the number of contracts that are outstanding and not yet exercised. Also, it is a good indicator of market activity. When open interest is high, it means that there are a lot of trades being made. When it’s low, there aren’t as many. But what exactly is open interest? And how does it impact daily trading volume?

We have got Ezekiel Chew, the founder, and CEO of Asia Forex Mentor, to share his take on open interest metrics. You can find hundreds of videos of him on YouTube, and he has been a speaker at several trading panels and Forex expositions. He is also one of the most successful Forex traders, and he closes deals worth six figures every single day.

Let’s hear his views on open interest options, how it works, their benefits, and more.

What are Open Interest Options

Open interest is one of the two key technical metrics responsible for describing the liquidity and activity of the current trading options and contracts traded. Open interest options are the total number of derivatives contracts or options of assets that are open for trading. In other words, open interest can also be referred to as the representation of the number of active or un-settled contracts. The open interest provides the accurate and ideal options trading activity picture.

Open interests reflect several contracts the investors and traders hold in active positions. These contracts are available and ready to be traded at any specified period. These active positions are the open trading positions that haven’t been closed, exercised, or reached their expiration date. There is a decrease in open interest once the buyers and sellers of the contracts close out a greater number of positions than those opened that particular day. To close out a position, a trader must exercise their position or take an offsetting position.

Open interest options increase again once the traders and investors start opening new long positions and start taking on the new place faster and greater in number than the closed contracts of that day. To gauge the strength of the market trend, open interest and other metrics are used by the technical analysts. The increase in open interest in the market is an indication that new traders are entering the market. It can also be used as a confirmation of a particular market trend.

How Open Interest Options work

It is important to know about the working of options and futures contracts to understand open interest options. In most cases, an option contract is prepared by a buyer. Every buyer in the market represents a particular seller. Any trader cannot buy something unless it is available in the sale. This buyer and seller relationship can be referred to as a contract responsible for translating approximately a hundred shares from the underlying assets.

When any contract is opened, it can only be closed if one of the two parties closes it. All the open interest options of a contract are the sum of all available warranties of both buyer and seller. Once a buyer and a seller engage with one another and create a new contract position, the value of open interest options rises. At the same time, this value decreases by one contract when the buyer and seller leave any particular place in the underlying stock. In simple words, you can say when the open interest decreases, the spread profit value also decreases.

In case the buyer or the seller transfers a particular position in the stock market to any other buyer or seller, the value of open interest options will not change. Therefore, open interest options can be calculated by providing the sum of all the opened trades and subtracting them once the trade is closed.

Open Interest Options vs. Trading Volume

Trading volume and open interest are two key technical metrics. They are responsible for describing the liquidity of futures contracts. In the stock market, the volume represents the number of times the shares change hands between buyers and sellers. The volume metric determines the number of options contracts bought or sold on a particular trading day.

Not only that, but it also enables determining the activity level on the trading day. No matter what transaction is opening or closing, each contributes to the daily volume and open interest. On the other hand, open interest options differ entirely from the trading volume no matter how much they are mixed up. It is the measure of all the available contracts in the stock market. This includes all the contracts that are open and held.

If a trader sells ten contracts to a trader who is new to the market, there won’t be any reflection of the transaction on the open interest. Since a trader is transferring all the contracts to a new trader, there will not be a new trading option added to the market with this transaction. Even selling all the arrangements to a new stock market trader will not affect the value of the trading volume. But this is not the case when the contracts are sold to an existing trader in the stock market. If an existing option buyer from a current option holder buys the contracts, the trading volume value will increase.

Benefits of Open Interest Options

Open interest options work similarly to the market activity measure. There is rarely any open interest option implying no opening positions in the stock market. If the open interest value is higher, more contracts are available in the market. This demands that the stock market traders and participants closely monitor the trading activities. As mentioned earlier, it also works as a cash flow measure in the options and futures contract.

If the open interest value increases, there is new or additional money in the market. On the contrary, if the open interest value decreases, the money flows out of the stock market. As the open interest options help determine the liquidity of the stocks, many options investors prefer this type of trading.

Open interest is quite helpful in determining the whole flow of the market, whether the new money is coming in or the money is going out of the stock market. It measures the total activity in the futures contract and provides a clear picture of options trading activities and the money flow in the stock market.

Trend Strength and Open Interest

Open interest options work perfectly for the indication of the trend strength of the stock market. The increase in open interest in the market represents the additional money and interest coming into the stock market. It can also be referred to as an indication that the existing market trend is rising or gaining momentum. It will more than likely continue for a while, benefiting the traders. This is how the trend strength is determined while keeping the open interest options in check.

For example, increasing open interest favors the market trend if the trend is rising for the price of any underlying asset in the stock market. This also ensures the continuation of a trend in the market. The same thing happens in the downtrends. The increasing open interest in the stock market is an indication that the stock price is declining. Open interest declines also indicate the weakening of a trend in the market.

The experts and most technical analysts believe that open interest options provide vital information about the stock market and its trends. For instance, if a sustained move is causing an open interest to decelerate, it might represent an end to the particular trend shortly. This is how much trend strength and open interest are related and are both integral parts of the stock market.

Open Interest Options FAQs

How do you trade with open interest?

One of the best ways to evaluate the overall trading activities is by using the open interest option. It helps to measure the number of outstanding contracts that are not yet exercised. If a seller ends the contract, the open interest option excludes the contract value. On the other hand, if they open a new one, the value is reflected.

The concept is valid for both the buyer and seller. Being a part of the contract adds to the value, and completing a contract detracts from it. However, if a new buyer purchases from the old seller, it doesn’t affect its value.

Should I buy options with high open interest?

While high open interest indicates a lot of trading activity, it doesn’t necessarily mean you should buy the options. The reason is that high open interest can result from traders taking positions to hedge their portfolios. In such cases, the options are less likely to be exercised.

Keep in mind that a high open interest does not always indicate an increase in the stock price. Instead, it indicates that the stock has a greater liquidity value. In short, traders are trading on that specific strike price, which depicts the market sentiment towards the stock and guaranteed selling of purchased stock.
