OKX Options provide a dynamic marketplace for traders seeking advanced strategies. Accessing comprehensive historical data is crucial for backtesting, market analysis, and developing quantitative trading models. This guide details the available historical data for OKX Options instruments, including coverage, access methods, and technical specifics.
Data Coverage and Availability
Historical market data for all OKX Options instruments has been systematically recorded and is available starting from February 1, 2020. This extensive timeline enables researchers and traders to analyze long-term market trends, volatility patterns, and the evolution of options trading on the OKX platform.
The dataset includes all major options trading pairs, capturing the complete market depth and trading activity across various strike prices and expiration dates. This comprehensive coverage ensures analysts can reconstruct market conditions for any trading day within the available timeframe.
Data Access Methods
Downloadable CSV Files
For users seeking convenient access to historical options data, Tardis.dev provides monthly CSV datasets. These files contain snapshots of market data from the first day of each month and are available for download without requiring an API key.
The CSV format offers simplicity for researchers and analysts who prefer working with spreadsheet applications or custom data processing scripts. These files maintain the original data structure as provided by OKX, ensuring accuracy and consistency with real-time data feeds.
API Integration
For programmatic access to the complete historical dataset, Tardis.dev offers a robust API system. The historical data format matches the structure of OKX's real-time WebSocket v3 API, with the addition of local timestamps for improved data synchronization and analysis.
The API provides several advantages for developers and quantitative analysts:
- Streamlined integration with existing trading systems
- Efficient data retrieval for specific time periods or instruments
- Real-time-like data structure for consistent processing
Data Normalization Options
While the raw data maintains OKX's native format, users have two options for working with normalized data structures:
CSV Normalization: The downloadable CSV files can be processed using data normalization tools to create a consistent format across multiple exchanges.
Client-Side Normalization: Official client libraries can transform the raw data into a standardized format during the retrieval process, simplifying cross-exchange analysis and comparison.

Technical Implementation
Data Collection Infrastructure
The market data collection system for OKX Options has evolved to optimize performance and reliability:
- Current Setup (Since May 4, 2022): Data collection occurs from AWS HK region (Hong Kong, China) using VPC colocation setup
- Previous Infrastructure (May 15, 2020 - May 3, 2022): GCP asia-northeast1 region (Tokyo, Japan)
- Initial Deployment (February 1, 2020 - May 14, 2020): GCP europe-west2 region (London, UK)
This multi-region approach ensures robust data capture with minimal latency and maximum reliability.
Connection Methodology
Real-time market data is captured through multiple WebSocket connections, providing redundancy and ensuring no data gaps during high-volatility periods. This sophisticated infrastructure connects to OKX servers located in Alibaba Cloud's cn-hongkong region (Hong Kong, China), optimizing for proximity and reduced latency.
Python Integration Example
Developers can easily integrate historical OKX Options data into their Python applications using the Tardis Client library. The following example demonstrates basic implementation:
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-options",
from_date="2020-02-01",
to_date="2020-02-02",
filters=[Channel(name="option/trade", symbols=[])]
)
async for local_timestamp, message in messages:
print(message)
asyncio.run(replay())This code snippet establishes a connection to the historical data API and retrieves options trade data for the specified date range. The asynchronous implementation ensures efficient data handling, particularly when processing large datasets.
