Trades says "Add an account to start trading"

What you see. Trades says “Add an account to start trading”, and no view shows your trades.

Why. There is no trading account yet. The setup wizard opens by itself only on a first launch with no account, so it does not come back on its own (by design).

What to do. Click Create an account, or open Settings → Accounts. To go through the wizard again, use Settings → General → Setup wizard → Run setup again.

See Set up Tented with the wizard and Accounts.
