Binance DEX

Binance DEX exchange historical data for all it's currency pairs is available since 2019-06-04.

​

Binance DEX real-time WebSocket API does not provide initial order book snapshots . To overcome this issue we fetch initial order book snapshots from REST API and store them together with the rest of the WebSocket messages - top 1000 levels. Such snapshot messages are marked with "stream":"<symbol>@depthSnapshot" and "generated":true fields.

​

Captured real-time channels

• ​trades​

• ​marketDiff​

• ​depthSnapshot (generated channel with full order book snapshots)

API Access and data format

Historical data format is the same as provided by real-time Binance DEX WebSocket API 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.

# pip install tardis-client
import asyncio
from tardis_client import TardisClient, Channel

  messages = tardis_client.replay(
    exchange="binance-dex",
    from_date="2019-12-01",
    to_date="2019-12-02",
    filters=[Channel(name="marketDiff", symbols=[])]
  )
