Last-traded price is the most recently reported transaction, not the current bid, ask, midpoint, or guaranteed executable level.
Read Last traded price together with Bid price, Ask price, Bid-ask spread. The comparison must preserve the exact rule, value, state, and evidence described below.
The venue reports a last trade at 100.00 while current bid and ask have moved to 99.98 and 100.02. The broker states which of those values feeds its chart, strike, and settlement.
Use the source that governs the exact contract, account, entity, or platform state. A general definition cannot replace current broker terms.
