:pushpin: What is Open Interest (OI)?

Open Interest (OI) is the total number of active (open) option contracts at a particular strike price.
It reflects where traders are taking positions and helps gauge market activity, sentiment, and potential support/resistance zones.

:magnifying_glass_tilted_left: Example:

  • Trader A buys 1 lot of Nifty 25,000 CE
  • Trader B sells 1 lot of the same option
    :white_check_mark: This creates 1 Open Interest
  • If another trader also buys/sells 1 lot → OI becomes 2
  • If someone exits the trade → OI goes down

:right_arrow: OI = Total number of live, unsettled contracts in the market

:high_voltage: Why OI Matters:

  • Spot where build-up or unwinding is happening
  • Identify key support/resistance zones
  • Detect trend continuation or reversal
  • Understand real-time market sentiment
