Questions
What is a good PCR?
Around 1 is balanced. Above 1.2 shows heavy put writing (traders expect support). Below 0.7 shows heavy call writing (traders expect a cap). Extreme readings can also mean the crowd is too one-sided.
Is this data live?
Yes, in market hours (9:15 am to 3:30 pm on trading days) the numbers refresh every minute without reloading the page. After the close you see the last session, and you can pick any saved past day.
Is this advice to buy or sell?
No. These are tools to read the market. They do not tell you what to trade. Options can lose all their value quickly; trade only what you understand and can afford to lose.
