What is OKX K-Line Data Skill?
The OKX K-Line Data Skill is a robust utility designed for developers and traders who need precise historical market data. It interfaces directly with the OKX exchange to pull candlestick information across a vast array of timeframes, ranging from 1-minute intervals to monthly aggregates.
By leveraging this skill within the Openclaw Skills ecosystem, users can automate the collection of price action data for popular pairs like BTC-USDT, ETH-USDT, and SOL-USDT. It effectively bypasses standard API volume limitations through a sophisticated timestamp-based pagination system, allowing for the reconstruction of deep historical price archives for backtesting or algorithmic analysis.
OKX K-Line Data Skill Use Cases
- Backtesting trading strategies using high-resolution historical price data.
- Building custom cryptocurrency dashboards with real-time and historical candle updates.
- Conducting technical analysis research across different timeframes like 4h, 1d, or 1w.
- Archiving market data for specific events or periods by using pagination to reach deep historical records.
How OKX K-Line Data Skill Works
- The user specifies a trading pair, timeframe, and the desired number of records via a CLI command.
- The skill sends a request to the OKX API to fetch the specified candlestick data.
- If specific historical dates are required, the skill utilizes the --after or --before parameters to anchor the query to a millisecond timestamp.
- The system processes the response, handling the OKX 100-record limit per request through sequential pagination.
- Structured market data is returned to the user for immediate analysis or storage.
OKX K-Line Data Skill Setup
To get started with this skill, ensure you have Node.js installed and access to the script directory. Run the following commands to query data:
# Fetch the last 30 daily candles for BTC
node scripts/okx-kline.js BTC-USDT 1d 30
# Fetch historical ETH data using a timestamp
node scripts/okx-kline.js ETH-USDT 4h 100 --after=1743500000000
