Rule definitions
Store rule versions with effective dates and explicit calculation inputs.
Account state machine
Define valid transitions between evaluation, failed, passed, funded, suspended and closed states.
Data quality
Validate trade and account data completeness before applying irreversible rule outcomes.
Real-time monitoring
Use event-driven or appropriately frequent processing for rules that require timely evaluation.
Disputes and review
Preserve calculation evidence and provide authorized manual-review workflows without silently rewriting historical outcomes.
Interventions
Restrict account disable/reset actions and log the reason and operator.
Consistency
Use one authoritative rule engine so CRM, dashboards and support tools do not calculate different outcomes.
