What is Open Interest?
Open interest represents the variety of contracts currently lively inside the marketplace. Buyers and sellers provoke those contracts; however, they have now not been offset with the aid of corresponding transactions. Open Interest represents the total number of active contracts in the market that have not been closed or expired. It indicates market participation and liquidity, though it should be interpreted cautiously as part of a broader analysis.
- High Open Interest: Indicates active trading, meaning there is significant participation in that contract.
- Low Open Interest: Reflects limited activity, which may suggest lower liquidity or waning interest.
Understanding open interest helps traders check whether a marketplace trend is supported by means of sturdy participation or is, in all likelihood, the opposite because of a lack of momentum.
How to Calculate Open Interest
Open interest changes whenever:
- A new buyer and seller enter into a contract (OI increases).
- An existing contract is closed or squared off (OI decreases).
Formula:
Open Interest=Total New Contracts−Closed Contracts\text{Open Interest} = \text{Total New Contracts} – \text{Closed Contracts}
For example:
- If two traders initiate a new futures contract, OI increases by one.
- OI decreases by one if another trader offsets their position by closing a contract.
Open Interest is calculated by exchanges and is publicly available on trading platforms and financial news sources for reference purposes.
Example of Open Interest
The following example is for illustrative purposes to explain the concept of Open Interest:
- Trader A buys one contract, and Trader B sells one contract. Open interest increases by 1.
- Trader C buys one contract, and Trader D sells one contract. Open interest increases to 2.
- If Trader A sells their contract to Trader E, open interest remains at two because a new participant replaces the existing one. This example demonstrates how Open Interest reflects active market participation rather than total trading volume.
This example demonstrates how open interest reflects active participation in the market rather than the total volume traded.
