Quote

A quote is current pricing information for buying or selling an instrument, usually including a bid, ask, size, timestamp, and relevant conditions.

A quote is a snapshot rather than a promise that the displayed price or quantity will remain available. Indicative quotes provide information but may not be executable, while a firm or locked quote is valid only under its stated size and expiry conditions. Market movement, data latency, venue access, and account checks can all cause the eventual fill to differ or the order to be rejected.
