Huobi Global (high caps)

Huobi Global historical data for high caps currency pairs is available since 2019-11-19.

​

Downloadable CSV files

Historical CSV datasets for the first day of each month are available to download without API key. See downloadable CSV files documentation.

​

API Access and data format

Historical data format is the same as provided by real-time Huobi Global 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
tardis_client = TardisClient(api_key="YOUR_API_KEY")

  # replay method returns Async Generator
  messages = tardis_client.replay(
    exchange="huobi",
    from_date="2019-12-01",
    to_date="2019-12-02",
    filters=[Channel(name="depth", symbols=["btcusdt"])]
  )

Captured real-time channels

​

• ​mbp (mbp.150, 100ms interval) - market by price incremental updates, available since 2020-07-03 During data collection integrity of order book incremental updates is being validated using sequence numbers provided by Huobi real-time feed (seqNum and prevSeqNum fields) - in case of detecting missed message (sequence gap) we fetch new snapshot via "req" request - it means that for brief moment of time between requesting a new snapshot and receiving it due to updates containing a gap reconstructed order book based on those updates may not be 100% valid. Initial order book snapshot is provided in this channel by requesting it via "req" request.

• ​trade​

• ​detail​

• ​bbo​

• ​etp - available since 2020-08-18

• ​depth (see also mbp channel that provided more granular updates)

  Collected with step0 aggregation level and provides data in 1-second intervals.

  Huobi Globaldepth real-time WebSocket channel always publishes full order book snapshots which are inefficient to store. To circumvent this issue we stored only initial book snapshots and then incremental updates instead - incremental updates are calculated by diffing two subsequent book snapshots and provided in the same format as other depth messages, except having additional update: true flag set as in snippet below. Update with amount (second value in array) set to 0 means such level should be deleted, otherwise price level should be updated with new amount value.
