Reading these numbers
- Max pain is the strike where option buyers collectively lose the most at expiry. It often drifts with price.
- 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, summed across every Deribit expiry. Crypto usually runs lower than Indian indices.
- Straddle vs range compares the ATM straddle price at the open (what options priced in) with the distance price actually covered.
