On Chainlink 24/5 U.S. Equity Streams, lastTradedPrice is deprecated as a production input. New integrations should not depend on it, and existing integrations should remove production dependencies by October 12, 2026. The field will remain in the RWA Advanced (v11) schema and may continue to be populated, but after October 12, 2026 it will no longer be monitored for availability, accuracy, or data quality on these streams. This change does not apply to other streams using the RWA Advanced (v11) schema.
