Connection flow
Connect. Review. Test. Deploy.
Authorize the account
Use the broker connection flow to grant the supported account access. Credentials stay with the broker or connection provider.
Review balances and positions
Confirm the account, buying power, and existing exposure before using it in an order or strategy.
Test away from capital
Use historical backtests and paper deployment to inspect behavior before choosing a live execution route.
Monitor every action
Track strategy status, fills, alerts, positions, and account activity from the Astral dashboard.
Move from backtest to broker with confidence.
Connect only after you have reviewed the strategy, its risk controls, and the account it will use.
