What is UIN (Unique Identification Number) on the PSX?
A UIN (Unique Identification Number) is the single identity NCCPL assigns to each investor in Pakistan's capital market, linking all of that investor's accounts across every broker. It allows trades to be netted per investor rather than per account.
How it works
Because the UIN follows the investor across brokers, UIN-level settlement data reveals how much of a day's trading actually changed ownership: if the same investor bought and sold through different brokers, UIN netting cancels it out.
PSX publishes daily UIN settlement reports per symbol — trade volume and value versus UIN-settled volume and value. The ratio between them (the delivery ratio) is one of the cleanest available measures of conviction versus intraday churn on the PSX.

Common questions
Why does UIN settlement matter for traders?
A stock can trade huge volume with almost no UIN settlement — meaning day traders passed it around without anyone keeping shares. High UIN settlement means real positions were taken, which is a stronger foundation for a move.
