About the ATOS data
Daily bars. 1,227 sessions from Nov 9, 2021 to Sep 25, 2026, one row per BMV trading day with open, high, low, close and volume. Prices are adjusted for splits and cash dividends so the series is comparable across its whole length; the API also serves the raw, split only and dividend only views.
Minute bars. Stored from Sep 23, 2026 forward, most recent session Sep 24, 2026. Minute history is captured from the day collection began and is never backfilled, so this start date is exact. Five minute, fifteen minute and hourly bars are derived from these minutes.
Time and currency. Session dates are BMV trading days; minute timestamps are UTC. Prices are in MXN. Volume is shares traded on the session.
Get the data. The REST endpoint returns the daily series as JSON with pagination; a free key serves the last year, Quant and above the full history back to Nov 9, 2021, and minute bars come with the paid windows. It takes timeframe (1Min, 5Min, 15Min, 1Hour, 1Day), adjustment, start and end. See the bars endpoint and authentication, and pricing for the plan windows.
