Introduction to Open Interest
Before entering futures and options trading, every trader should understand the concept of open interest. It is one of the most powerful tools used in technical analysis.
Many beginners focus only on price movement. But professional traders look beyond price. They want to know whether fresh money is entering the market or leaving it.
That is where open interest becomes useful.
Open interest tells traders how many active contracts exist in the market. It gives an idea about market strength, trader participation, and possible future trends.
What is Open Interest?
Definition of Open Interest
If you are wondering what is open interest, here is a simple explanation.
Open interest refers to the total number of active futures or options contracts that are not yet closed or settled.
Whenever a buyer and seller create a new contract, open interest increases. When traders close positions, open interest decreases.
Simple Example
Imagine two traders create one futures contract:
- Buyer purchases one contract
- Seller sells one contract
Now open interest becomes 1.
If another pair creates a new contract, open interest becomes 2.
This number keeps changing throughout the trading session.
Why Open Interest Matters
Open interest helps traders understand:
- Market participation
- Trend strength
- Possible reversals
- Institutional activity
- Support and resistance zones
Without open interest, price analysis alone may sometimes give incomplete signals.
Difference Between Volume and Open Interest
Many beginners confuse volume with open interest.
Volume
Volume shows how many contracts were traded during the day.
Open Interest
Open interest shows how many contracts remain active.
Quick Comparison
| Volume | Open Interest |
| Measures trading activity | Measures active contracts |
| Resets daily | Carries forward |
| Indicates market activity | Indicates money flow |
| Short-term data | Trend strength indicator |
Both are important, but open interest often gives deeper insights into trader behavior.

Why This Signal Is Powerful

Similarly:
- Price increasing = demand rising
- Open interest increasing = more traders participating
Together, they often confirm market strength.
