FAQs

What is the put-call ratio (PCR)?
The put-call ratio compares open Put contracts with open Call contracts for one expiry of an index or stock. It is calculated as total Put open interest divided by total Call open interest. A PCR of 1 means equal Put and Call open interest. Sahi's chart recalculates it every five minutes through the session.
What does a PCR above or below 1 mean?
A PCR above 1 means more Put contracts are open than Call contracts on that expiry; below 1 means more Call contracts are open.
What is the difference between OI PCR and volume PCR?
OI PCR uses open interest, the contracts still open, so it reflects positions carried over time. Volume PCR uses the contracts traded in the current session, so it reacts faster and swings more within the day.
Why is PCR calculated for each expiry separately?
Each expiry is a separate set of contracts with its own positions. Weekly and monthly expiries can hold very different open interest, so mixing them blends unrelated positions. Reading PCR per expiry keeps the ratio tied to one set of contracts.
Why does the PCR change during the trading day?
PCR moves whenever Put or Call open interest changes. New Puts opened, or Calls closed, push it up. New Calls opened, or Puts closed, push it down. Tracking it through the session shows which side traders are adding to.
How do traders use the PCR?
Traders use PCR to see whether more Put or Call contracts are open on an expiry and how that balance is shifting. Many compare the current reading with its own range over recent sessions, because a typical level differs from one instrument and expiry to another.
