Intrinsic and extrinsic values are signed by position size. Extrinsic value is the option premium minus spot-based intrinsic value.
THE FRAMEWORK
How the Plate works
Strike rings stay fixed
Each ring marks a strike. Its distance from the spot ring determines the spot-based intrinsic value of the call or put.
The spot ring follows NIFTY
As the market or scenario spot moves, the ring crosses strikes and the contracts’ moneyness changes.
The thermal layer shows extrinsic value
UDP maps the model premium minus intrinsic value to a signed display quantity. The pricing model supplies the premium.
