The combined call and put premium makes the straddle
Max pain is the settlement price that minimises the total intrinsic payout of calls and puts for one expiry, weighted by open interest. The panel uses the full expiry chain available to the server, rather than just the ATM rows shown beside the straddle chart.
Use the Nifty expiry chips above the chart. Max pain, PCR and the largest call and put OI strikes refer to that selected expiry. Switching expiry clears the previous reading until the new snapshot arrives.
Max pain is an underlying price level based on positioning. The straddle line is a combined option premium. Read them alongside each other; their values are on different scales. OI concentration does not guarantee support, resistance or an expiry settlement.
The timestamp belongs to the OI snapshot. Outside market hours, or when the feed has insufficient OI, the panel can be unavailable even though the chart has an archived session. Historical straddle comparisons do not reconstruct historical max pain.
The one selected in the Nifty expiry chips above the chart. Max pain, PCR and the largest call and put OI strikes all refer to that expiry, and switching expiry clears the previous reading until the new snapshot arrives.
The open-interest put-call ratio is total put OI divided by total call OI for the selected expiry. A missing value means the feed cannot supply a valid ratio.
No. It summarises current positioning and can change as open interest changes. It is not a forecast of the settlement price.
