Open interest is like the potato of the trading world – nobody really pays attention to it until it’s gone. But just like how the absence of potatoes can ruin a good meal, not understanding open interest can ruin your trading strategy. It’s that silent factor that quietly affects the market, and only the wise ones who pay attention to it get to enjoy the delicious profits. So don’t underestimate the power of open interest, my friends. It may seem unassuming, but it’s a mighty ingredient that can make or break your trades.
What is Open Interest?
OI is the total number of outstanding contracts that are held by market participants at the end of each day. Open interest measures the total level of activity into the futures market. It can also be defined as the total number of futures contracts or option contracts that have not yet been exercised (squared off), expired.
The primary application of the role of open interest is in futures market. OI, or the total number of open contracts on a security, is often used to confirm trends and trend reversals for futures and options contracts. OI measures the flow of money into the futures market. For each seller of a futures contract there must be a buyer of that contract.
Thus a seller and a buyer combine to create only one contract. Therefore, to determine the total open interest for any given market we need only to know the totals from one side or the other, buyers or sellers, not the sum of both.
The open interest position that is reported each day represents the increase or decrease in the number of contracts for that day, and it is shown as a positive or negative number.
How does Open Interest work?
Each trade completed on the exchange has an impact upon the level of open interest for that day.
For example, if both parties to the trade are initiating a new position (one new buyer and one new seller), open interest will increase by one contract. If both traders are closing an existing or old position (one old buyer and one old seller) open interest will decline by one contract.
Open Interest as an indicator
There are four main interpretations of OI:
If price increases and open interest increases, then participants are having more of long positions.
If price decreases and open interest increases, then participants are having more of short positions.
If price increases and open interest decreases, then Participants are short covering their contracts.
If price decreases and open interest decreases, then participants are long covering their contracts.
Open interest is the total number of outstanding derivative contracts, such as options or futures that have not been settled.
Open interest equals the total number of bought or sold contracts, not the total of both added together.
Open interest is commonly associated with the futures and options markets.
Increasing open interest represents new or additional money coming into the market while decreasing open interest indicates money flowing out of the market.
