📥 Downloadable CSV Files – No API Key Required
One of the most user-friendly features is the availability of free downloadable CSV files for the first day of every month. These datasets require no API key, lowering the barrier to entry for researchers and newcomers.
These CSVs are perfect for:
- Quick exploratory data analysis
- Educational purposes
- Validating data quality before committing to larger downloads
For full details on file structure and download links, refer to the Downloadable CSV Files documentation.
💡 Pro Tip: Use these sample datasets to prototype your data pipeline before scaling up with API access.
🔌 API Access & Real-Time Data Format
The historical data mirrors the format delivered by OKX’s real-time WebSocket v5 API. Prior to December 23, 2021, data was collected using the v3 API, so users should account for version-specific differences when analyzing older records.
Each message includes:
- Raw exchange data
- Local timestamps (added for precision)
If you prefer a normalized data format—where fields are standardized across multiple exchanges—you can use:
- The downloadable CSV files (pre-normalized)
- Official client libraries that handle normalization client-side
Here’s an example using the Python tardis-client to replay historical data:
# pip install tardis-client
import asyncio
from tardis_client import TardisClient, Channel
tardis_client = TardisClient(api_key="YOUR_API_KEY")
async def replay():
messages = tardis_client.replay(
exchange="okex-futures",
from_date="2023-01-01",
to_date="2023-01-02",
filters=[Channel(name="books-l2-tbt", symbols=[])]
)
async for local_timestamp, message in messages:
print(message)
asyncio.run(replay())For more code examples and setup instructions, see the Python Client Documentation.

📡 Captured Real-Time Data Channels
A wide range of WebSocket channels are recorded, enabling granular analysis of market dynamics. Below is a breakdown of available channels.
V3 API Channels (Recorded Until December 23, 2021)

- bbo-tbt – Best bid/offer updates
- tickers – Summary metrics like last price and 24h volume
- open-interest – Total outstanding contracts
- mark-price – Fair value pricing to prevent manipulation
- price-limit – Daily price caps
- status – Exchange system status
- instruments – Contract specifications
- index-tickers – Underlying index prices
- long-short-account-ratio – Retail trader sentiment

These channels empower traders to reconstruct market conditions with high precision.
🏗️ Market Data Collection Infrastructure
Data integrity starts with robust collection infrastructure. Here's how OKX Futures data is captured:
| Period | Location | Cloud Provider |
|---|---|---|
| Since May 4, 2022 | Hong Kong, China | AWS (HK region, VPC colo setup) |
| May 15, 2020 – May 4, 2022 | Tokyo, Japan | Google Cloud Platform (asia-northeast1) |
| Initial Collection | London, UK | Google Cloud Platform (europe-west2) |
Real-time data is pulled via multiple WebSocket connections, ensuring redundancy and minimizing missed messages. The proximity of collectors to OKX’s own servers—located in Alibaba Cloud’s cn-hongkong region—reduces latency and increases data accuracy.
This global infrastructure setup ensures reliable capture even during high-throughput events like flash crashes or major news releases.
