Derivatives: risk first
Model contract meaning, collateral, sensitivities, and unfilled hedges without confusing intent with exposure.
MARKET TRACK / DERIVATIVES
Exposure before throughput. Keep notional, margin, sensitivities, outstanding orders, and intended hedges distinct.
A derivatives adapter must represent the actual contract, not only its underlying asset. Record payoff parameters, settlement convention, currency, expiry where relevant, and applicable lifecycle events. Similar-looking tickers can imply different obligations and different valuation inputs.
Keep contract count, notional where meaningful, margin information, and modeled sensitivities separate. Model outputs should carry their version and input context. A collateral requirement is not a complete estimate of possible loss, and an intended hedge is not an executed offset.
Include outstanding orders and unresolved requests in the permission model. When one leg executes and another does not, calculate the residual exposure using the actual instruments. Do not mark a multi-leg intention complete because all of its network messages were sent.
Stress a paired workflow by rejecting one leg, delaying an account update, and changing an approved valuation input. Require the system to explain the resulting position, stop new exposure when policy requires, and preserve the evidence needed for reconciliation and resumption.
Continue with the complete derivatives field guide, which includes a primary reference and practical test scenarios. Use the architecture blueprint for the shared system model and the risk checklist for permission and recovery. Confirm actual product terms with the relevant provider before any implementation.
