<DataStreams section="dsNotes" />

Cryptocurrency streams adhere to the report schema outlined below.

## Time-Weighted Average Price (TWAP)

The v2 schema is used by TWAP streams. The `price` field carries the time-weighted average price for the stream's configured window, not a spot or median price. Each TWAP stream is scoped to one asset and one window length (for example, 30 seconds or 60 seconds). The window length is part of the stream's name and metadata.

## Schema Fields

**Note**: Future Cryptocurrency streams may use different report schemas.
