OI Dashboard
Where open interest sits for every F&O underlying: max-OI strikes, put/call ratios, share of new positions, max pain and implied volatility.
How to read this pageShow
- Max CE / PE OI strike
- The strike price where the most call (CE) or put (PE) contracts are open, and how far the price is from it.
- Share of new OI
- Of all the open interest added today, how much came from calls and how much from puts. The two always add up to 100%.
- PCR (put/call ratio)
- Put open interest divided by call open interest. ATM±5 and ATM±2 look only at strikes near the current price.
- Max pain
- The strike at which option holders, taken together, would have the least value at expiry.
- ATM IV
- The yearly volatility that at-the-money option prices imply for this expiry.
- Straddle %
- The cost of the at-the-money call plus put, as a share of the price.
