Understanding Open Interest and Its Abbreviation

What is Open Interest?

Open Interest (OI) refers to the total number of outstanding derivative contracts, such as futures or options, that have not been closed or delivered on a particular trading day. It represents the total number of positions that are yet to be squared off by an offsetting trade or exercise. In other words, it is a measure of market activity and represents the number of contracts that are not yet liquidated or settled.

Why is Open Interest Important?

Open Interest is a crucial indicator for traders and analysts as it provides insights into the liquidity and overall market sentiment for a particular derivative contract. It indicates the level of participation and the number of positions that exist in a particular instrument. High open interest suggests a high level of active trading, while low open interest may indicate lower market participation. It can be used to gauge whether the market trend is gaining or losing momentum.

Traders and analysts often refer to OI figures when analyzing market trends, identifying potential price reversals, or assessing the overall market sentiment towards a specific instrument or contract.

How is Open Interest Calculated?

Open Interest is calculated by aggregating the number of open long positions and open short positions in a particular derivative contract. If one trader holds a long position (buy) and another trader holds a short position (sell), the open interest for that contract is considered as two.
