Important Notes

Use these exact exchange identifiers. They are case-sensitive.
Some exchanges do not have all data types.
Mark price, open interest, and liquidations are available only on futures/derivatives exchanges.
Before you send requests, make sure that data is available for the trading pairs that you need.
chd.exchanges.BITMEX has only historical data. BitMEX closed in September 2026. Its files end on 2026-09-22.
