Kraken WebSocket API (spot) as the core of the trading bot
The search intent “Kraken API websocket trading bot” matches an engine that multiplexes persistent connections, routes `req_id`s, and treats reconnects and token rotation seriously.
REST is slow for high-frequency state sync; the bot uses WebSockets for market data (public) and private streams for balances, executions, and order lifecycle. Truth for fills is user-data, not a single REST response.
A fully autonomous bot is not a loose cron job: connections are long-lived, with backpressure and bounded queues — unlike a script that REST-polls every minute.
KapitaalBot.nl does not show a live order feed; observability is read-model snapshots (Tier 1/2) for transparency without leaking strategy.
