What is Open Interest?
Open Interest is a concept used in futures and options trading that measures the number of contracts that are being held by market participants. These contracts can be either bought or sold, but have not yet been exercised, expired, or offset by opposite transactions.
Why is Open Interest important?
Open Interest is an important indicator for traders and investors as it can provide insights into the liquidity, strength, and depth of a market. High open interest suggests that there are many contracts that are currently open, which can mean a greater possibility of these contracts being closed profitably. Conversely, low open interest could indicate a lack of liquidity, which can lead to difficulty in entering or exiting positions.
Who uses Open Interest?
Open Interest is used by various market participants, including traders, investors, and analysts. Traders use it to gauge the market sentiment and to identify potential trend reversals. Investors may use open interest to understand the liquidity of a particular futures or options contract. Analysts often use open interest data to forecast price trends and volatility in the market.
When is Open Interest used?
Open Interest is used throughout the trading day by market participants to make decisions about buying or selling futures or options contracts. It is also used in the analysis of market trends over longer periods.
How is Open Interest calculated?
Open Interest is calculated by adding all the open contracts at the end of each trading day. For example, if trader A buys 5 contracts from trader B who is selling 5 contracts, the open interest would increase by 5. If trader A sells 5 contracts to trader B who is buying these 5 contracts, the open interest would decrease by 5. If a new contract is initiated by trader A buying from trader B who is selling, the open interest would increase by 1.
