Automate spot crypto on Kraken, and set the nonce window first
The one Kraken detail that trips people up is a setting on the API key itself. Get that right and the rest is a normal signal-to-exchange webhook workflow for spot crypto.
Position limits count each pair
If you set a maximum on strategy positions, crypto limits are per pair. Enter the full pair, not the bare BTC, when you create a limit.
Pairs counted separately
- BTC-USD Counted Its own count
- BTC-USDT Counted Counted separately from BTC-USD
Compare the crypto page for the other connections that accept spot crypto.

Kraken: 5 things that work differently
-
Setup Kraken connects with an API key, not a login
Create the key in Kraken, copy it, and paste it into TradersPost. The steps are above.
-
Orders Exits are separate signals
Kraken takes simple orders only, so take profit and stop loss cannot be attached to the entry. Send the entry first, then send a separate signal later to exit for take profit or stop loss.
Order classes (opens in a new tab) -
Orders No trailing stops
Kraken does not offer trailing stop orders.
-
Orders Exits close in your default quote currency
Kraken closes and exits a position in your default quote currency, USD unless you change it in the connection settings.
-
Account No paper trading
Kraken has no paper mode on TradersPost. Rehearse a strategy on the TradersPost paper broker first, or start with small live sizes.
