Understanding Open Interest
Simply put, open interest refers to the total number of option contracts that have been bought and not yet closed or exercised. It is a measure of the number of outstanding contracts for a particular option series or strike price. This information essentially tells you how many options are actively participating in the market.
Importance of Open Interest
Open interest serves as a barometer of market sentiment and trading activity. A high open interest indicates that there is a substantial amount of interest in a particular option contract or underlying security. It suggests that there are ample buyers and sellers actively engaged in trading that option.
Furthermore, open interest can provide clues about the direction of the underlying security. Rising open interest alongside a price increase in the underlying asset often signals a bullish sentiment, as traders are betting on further price appreciation. Conversely, falling open interest coupled with a declining price may indicate a bearish outlook.
Calculating Open Interest
Calculating open interest is a straightforward process. To determine the open interest for a specific option contract, you need to subtract the number of exercised contracts from the total number of contracts that have been traded. This can be expressed as:
Open interest = Total contracts traded – Exercised contracts

Measuring Market Depth: High open interest indicates a liquid option market with ample buyers and sellers, reducing the risk of price slippage and facilitating smooth trading.
Gauging Market Sentiment: Open interest can provide insight into the overall market sentiment surrounding a particular option contract or underlying security.
Validating Trading Signals: By comparing open interest to other technical indicators, you can validate your trading signals and enhance your confidence in making informed decisions.
