This message means Kraken has temporarily blocked your bot from making API calls because it exceeded Kraken's rate limit. Your bot will automatically resume after 15 minutes.
Cause
Kraken enforces strict API rate limits compared to other exchanges. Your bot can hit these limits in two ways:
It places too many orders in a short time.
It has multiple open orders that can't be automatically canceled due to a high nonce value in your Kraken configuration.
How to reduce the chance of a lockout
Use two API keys — In your bot's configuration, set up two separate Kraken API keys. This spreads the API calls across both keys and reduces the chance of hitting the rate limit. See how to connect to Kraken with API keys for setup instructions.
Set the nonce value to 10,000 — A high nonce value can prevent Cryptohopper from canceling open orders, which leads to extra API calls. Make sure the nonce is set to 10,000 as explained in step 5 of this guide.
Remove stuck orders manually — If you have open orders on Kraken that your bot can't cancel, remove them manually through the Kraken interface.
Avoid using Kraken for Market Making or Arbitrage bots — These bot types place a high volume of orders, which makes Kraken lockouts very likely.
Consider switching to a different exchange — If you frequently hit Kraken's rate limits, Coinbase or another exchange available in your jurisdiction may be a better fit for your trading strategy.
Good to know
Kraken is currently the only exchange where Cryptohopper regularly encounters API rate limit issues. This is a limitation on Kraken's side that can't be bypassed. Cryptohopper is in regular contact with Kraken about these limitations.
