Captured real-time channels

• ​depth​

• ​trade​

• ​detail​

• ​bbo​

depth channel was collected with step0 aggregation level (no aggregation).

Huobi Global depth real-time WebSocket channel produces full order book snapshots for each book change which is very inefficient to store. To circumvent this issue we store 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.

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>")
​
async def replay():
  # 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"])]
  )
​
  # messages as provided by Huobi Global real-time stream
  async for local_timestamp, message in messages:
    print(message)
​
​
asyncio.run(replay())

// npm install tardis-dev
const { replay } = require('tardis-dev');
​
async function run() {
  try {
    const messages = replay({
      exchange: 'huobi',
      from: '2019-12-01',
      to: '2019-12-02',
      filters: [{ channel: 'depth', symbols: ['btcusdt'] }],
      apiKey: '<YOUR_API_KEY>'
    });
​
    // messages as provided by Huobi Global real-time stream
    for await (const { localTimestamp, message } of messages) {
      console.log(localTimestamp, message);
    }
  } catch (e) {
    console.error(e);
  }
}
​
