Read-only API keys
Astro connects to Kraken with read-only permission, so your account is never at risk of an unauthorized trade.
Connect Kraken with a read-only API key in the Astro iOS app and your spot trade history flows into the journal, sized in coin units, ready to review by symbol, direction, and setup.
Kraken has been running since 2011 and has earned a reputation for security and compliance that attracts traders who approach the market with care. Astro fits that profile: it builds the journal from your actual trade history rather than relying on manual entry, and the read-only API key it uses has no ability to touch your positions.
Once connected, Astro reads your spot fills as they arrive and records them as durable journal entries. You get a clear, accurate record of what you traded, when you traded it, and how each position sized up in coin units, without any cleanup work on your end.
Kraken serves both USD and EUR markets, so many of its traders hold positions quoted in different fiat currencies at the same time. Astro keeps each trade in its own quote currency rather than converting at the moment of import, so a BTC/USD fill and a BTC/EUR fill each carry their own honest number.
A reporting currency ties everything together. Set one currency and Astro rolls all your totals into it consistently, so you can compare a USD pair against a EUR pair or see the full account picture without mixing exchange rates mid-calculation.
The review layer in Astro organizes your Kraken history around the questions that matter: which coins produce results for you, whether longs or shorts have the better record, and which setups tend to hold up over time. Group setups into playbooks to track repeatable approaches across coins.
Add a reflection note on any trade worth a second look. Over time, a Kraken journal in Astro becomes a personal archive of what you did and why, with sizing and currency kept accurate throughout.
