A last-reviewed date records when the stated subject was checked. It is not a promise of continuous market monitoring, a scheduled update service or a certification by an outside reviewer.
Review order
Financial correctness and misleading risk statements come first, followed by changing contract rules, obsolete services, regulatory warnings, language and technical quality. Shared definitions should be corrected before individual copies.
Historical material
Useful old examples and URLs may be retained, with historical status made clear. When a market or contract has changed, consult the current exchange information. An educational worked example does not assert that its quoted price, margin or instrument remains available.
When another review is needed
A substantiated correction, exchange rule change or failed calculation test calls for another review of the affected content. Pages without a scoped review date should not be assumed to have received a complete financial review.
