Kraken API Offers Diverse Market Data Feeds for Systematic Traders

Kraken's Application Programming Interface (API) offers a range of market data feeds to systematic traders, enabling them to access real-time and historical data. This data is crucial for trading strategies, as it helps traders make informed decisions. The API provides various feeds, including L2 order book depth, OHLCV (open-high-low-close-volume), and funding rate data.

The choice of feed depends on the trader's strategy type. For example, execution algorithms commonly use L2 order book depth with a minimum of 10 levels to avoid slippage. On the other hand, backtesting often requires OHLCV data for moving averages and RSI calculations. Funding rate data is essential for carry strategies that harvest periodic payments between longs and shorts on perpetual futures.

When using crypto market data feeds, traders should be aware of common mistakes. Using WebSocket for everything can be unnecessary, as REST polling is simpler for backtesting or slow strategies. Assuming L3 (individual order visibility) is necessary when L2 (aggregated depth) is sufficient can also lead to inefficient usage of resources.

To get started with Kraken's API, traders can begin with ticker and OHLCV data via REST, which are public and simple to integrate. As they move to live execution, they can add order book and trade feeds. Experienced traders should identify their strategy type and pick 2-3 feeds that directly feed their signals or execution logic.
