Download / Schemas

Schemas

Every dataset can be downloaded in one of three schemas. The data is identical across schemas. Only the way rows, columns, and files are organized changes. Pick the one that matches how your code consumes the data.

Long: One row per asset and timestamp, with the asset in a base column. One file.
Wide: One row per timestamp, one column per asset and field, named BTC_close. One file.
One file per asset: One file per asset, one row per timestamp.

Columns

Whatever the schema, a download covers one source, one interval and one quote currency, and every candle carries these fields. The wide schema repeats the six price and volume fields once per asset.

Column	Type	Description
close_ts	datetime[us, UTC]	Close time of the candle, UTC.
open	float64	Price at the start of the candle.
high	float64	Highest price during the candle.
low	float64	Lowest price during the candle.
close	float64	Price at the end of the candle.
base_volume	float64	Volume traded, in the base asset (BTC for BTC/USDT).
quote_volume	float64	Volume traded, in the quote asset (USDT for BTC/USDT).

The examples on the next pages use the same hourly sample for BTC/USDT and ETH/USDT on 2026-10-01, so you can compare the schemas directly. To pick a schema and generate a file, open Download in the platform.
