Reading these numbers
- Max pain is the strike where option buyers collectively lose the most at expiry. It often drifts with price, and the pull tends to strengthen into expiry.
- Fresh OI shows where option writers opened new positions during the session. Heavy put writing below price often marks a level sellers expect to hold; heavy call writing above marks a ceiling.
- PCR is put OI ÷ call OI for the monthly expiry.
- Straddle vs range compares the ATM straddle price at the open (what options priced in) with the distance price actually covered.
