What you need
Lighter connects with a read-only token. It lets TradeDNA see your trades and positions, never place orders or move funds. Your history syncs from the moment you connect.
1. Get your read-only token
In Lighter, open Tools, then API Keys, then Read-Only Token, and choose Generate Read-Only Token. Leave Allow Sub-Account Access on, and set Expiry Days as high as it allows. The default of 30 means syncing would stop in a month. Then generate and copy the token, it starts with ro:.
2. Add the connection
In TradeDNA, go to Settings, then Connections, open the Auto-sync tab, choose Add auto-sync account, and pick Lighter. Paste your token into Read-only token, add an optional Account label, and choose Connect Lighter.
3. Done
When it connects, you will see your trades imported, and new trades sync on their own from here.
