What is Open Interest on the PSX?
Open interest (OI) is the number of futures contracts that remain open — neither closed nor delivered — in a PSX Deliverable Futures Contract. Rising OI means new positions are being created; falling OI means positions are closing.
How it works
OI is measured in contracts, but the more useful readings are OI volume as a percentage of the stock's free float (how much of tradable supply is controlled through futures) and the day-over-day change in contracts (fresh positioning versus unwinding).
A caution when reading OI in value terms: OI value equals contracts times price, so a price rally alone inflates OI value without any new positioning. Contract counts are the honest measure of build-up.

Common questions
What does rising open interest with rising price mean?
The classic reading is fresh leveraged buying (long build-up). It is more reliable when measured in contracts rather than value, and outside rollover week — near expiry, OI shifts are partly mechanical.
