A rounded Settlement price display cannot resolve equality when stored precision and Barrier breach differ.
Read Settlement price together with At-the-money settlement rule, Barrier breach, Expiry-only observation. The comparison must preserve the exact rule, value, state, and evidence described below.
A broker candle and external chart disagree on Settlement price: one uses midpoint and another last trade. Matching instrument and price type explains At the money settlement rule. The operative detail for Settlement price is concrete: the final stored quote, side, source, precision, and timestamp decide whether the condition was met.
Use the source that governs the exact contract, account, entity, or platform state. A general definition cannot replace current broker terms.
