DataType¶

Defined in dccd.domain.types

class DataType(*values)[source]

Bases: str, Enum

Core data types supported by dccd v3.

The enum is intentionally closed. Extensions (funding, OI, liquidations) will require adding a new member here AND implementing the corresponding domain models and source protocols — never bypassed by string comparison.

Examples

>>> DataType.OHLC
<DataType.OHLC: 'ohlc'>
>>> DataType('trades')
<DataType.TRADES: 'trades'>
