AscendEX (BitMax)

AscendEX historical market data details - available instruments, data coverage and data collection specifics

AscendEX exchange historical data for all it's instruments is available since 2021-03-28.

Downloadable CSV files

Historical CSV datasets for the first day of each month are available to download without API key. See downloadable CSV files documentation.

API Access and data format

Historical data format is the same as provided by real-time AscendEX Exchange WebSocket API v2 (https://ascendex.github.io/ascendex-futures-pro-api-v2/#websocket) with addition of local timestamps. If you'd like to work with normalized data format instead (same format for each exchange) see downloadable CSV files or official client libs that perform data normalization client-side.
