We've identified an issue affecting some tickers where OHLCV values are inaccurate for the market day of 07/23/2025. This issue will self-resolve when the market day rolls over to 07/24/2025 at midnight Eastern Time. We're working to backfill the correct data for 07/23/2025, and it will be available starting at midnight Eastern Time on 07/25/2025.
