description: "Computes three related derivatives calculations from one declared position: event-market linear PnL (settlement vs strike, scalar payoff), margin health (unrealized PnL, buffer, liquidation price, leverage) against a caller-declared venue margin model (regulated-DCM or offshore-perp class, with its own initial/maintenance margin rates rather than an internal per-venue lookup table), and, when a second position is supplied, two-leg correlation-VaR cross-margin efficiency (siloed vs shared capital requirement). Scope: closed-form pedagogical approximations of the same computations live risk engines run, not a stress-grid or SPAN-style margin system, and not financial advice."
