What changed
OPK now adds a fixed active-contract dock at the bottom of mobile calculation pages. Once the contract identity is complete, the dock shows ticker, strike, side, and expiration together with expiration probability of profit and expiration breakeven.
The deep navy treatment separates the dock from the white page and keeps it readable while you move through Trade Details, IV Inputs, Estimate Summary, Greeks, and the stock-price chart. Its values follow the live contract fields rather than an older calculation snapshot.
Designed around the keyboard
The dock disappears immediately when you focus an editable control and remains hidden while the on-screen keyboard compresses the viewport. It returns only after the keyboard transition has settled, so it does not cover or intercept Calculate and other nearby controls.
When required pricing or IV inputs are incomplete, the contract identity can remain visible while unavailable POP or breakeven values show a dash. OPK keeps the context without presenting stale metrics as current.
