How is this computed?
The solid line is P&L at expiry (green profit / red loss); the dashed teal line is today's value. The white line is spot, the gold dotted line is breakeven. The entry price is the Black-Scholes theoretical mark derived from OKX's IV.

OKX + BSM0s ago
How is this computed?
Rows are IV shifts (vol points), columns are spot shifts (σ = the expected move). Each cell is the position's value today as a % return on entry cost. Green is profit, red is loss. It shows vega and gamma effects in one view.
