Beginners may find stock trading confusing and unclear. However, if you are looking to invest, you need to understand the instrument and the different investing strategies. An option in the stock market is a financial contract that consists of a potential underlying asset in the stock market. This option contract allows traders to buy or sell the underlying asset. The option holder can decide whether they want to buy or sell the underlying assets. Suppose they choose to execute the deal before the contract expires. Then, according to options trade, the profit or loss can vary for them. As an options trader, you need to check the underlying assets on their own and check the strike price of the assets.
Quantitative indicators like trading volume and open interest (OI) are important tools of options trading. However, in this article, you will learn about the market trends of options trading, as well as the meaning and implications of OI, beginning with an answer to the question of what is OI in options and more about plan investing.
What is Open Interest in the Share Market?
The open interest tells you how many contracts are open and active in the current market. There are outstanding contracts in the market due to a pending delivery or settlement, and the trader has discretion for this call trade. As the contract is considered open until the second party closes it. So, let us look at how the OI will be affected in the following scenarios.
- In the first scenario, a buyer and seller initiate a new position in an options trade. Here, the OI rises by 1.
- In the second scenario, both traders exit a contract position on a trade, and this results in the OI falling by 1.
- The last scenario is if the buyer or seller passes off their position to other traders. Here, the OI value remains unchanged.
In short, an increasing open interest exhibits additional money that is coming into the market, and a decreasing open interest shows the money flowing away from the market.
What Does the Open Interest in Put and Call Options Indicate?
The OI indicates the level at which the trader had to build positions and reflects whether the market will go up or down. A high level of open interest built up for a call option at a particular strike price implies resistance at the strike price. Whereas the high OI built for a put option will reflect a particular strike, implying support for a particular price.
Importance of Open Interest
Open interest helps traders in the derivatives market know whether the market is getting stronger or weaker. Open interest is the combination of share prices and trading volume. This data helps traders get a strong indication of future trends and enhance their profits.
Increasing the stock price along with an upward movement is an indication of open interest, which is indicative of a bullish trend. An increase in stock prices, along with declining open interest, is an indication of a bearish trend. This indicates a short covering in the market and money is exiting the market. Consider an example of both parties trading and initiating a new position. Then the open interest will also increase. In short, you can say that open interest impacts the futures and options contracts.
Open Interest and Volume
Volume and Open Interest (OI) differ in options trading. OI represents open contracts in the derivative market, while volume indicates the total number of contracts executed in a day, counting each transaction as 1, not 2. For instance, if seller X sells 7 futures contracts and buyer Y purchases all 7, both volume and OI end at 7. If later, Y sells 5 contracts to Z, the volume changes to 5, but since no new contracts are added, the OI remains unchanged at 7. Unlike volume, OI may persist for days, measuring initiated or old contracts that have been settled or executed.
Benefits of Open Interest
The benefit of options trade in the derivative market is that by monitoring the OI you can figure out whether at the end of each trading day, there is some activity or not in the stock market.
Increasing OI means an indication of money flowing in the market. And in declining OI the market is liquidating and traders are exiting their respective trade. A change in OI is an alarm bell for traders that an uptrend or downtrend will be hitting the market.
Conclusion
Grasping the significance of OI in options trading is fundamental for informed decision-making. Unlike volume, which measures daily transactions, OI provides insights into the total number of open contracts in the derivative market. This distinction is crucial for traders, as OI reflects the sustained interest and commitments in the market over time. By understanding the relationship between volume and OI, investors can gain a comprehensive understanding of market dynamics, aiding them in developing effective trading strategies and navigating the complexities of options trading with greater confidence.
