Pull up AAPL daily with SMA 10 and overlay my latest backtest trades.

I’ll pull the daily AAPL series, add a 10-day simple moving average, and match it with your most recent authorized backtest. Then I’ll place the entries and exits on the same chart so the signal timing is easy to inspect.

Visit the help center

What can I do with Astral?

Research markets, build rule-based strategies through conversation, inspect the generated code, run backtests, monitor alerts, and connect a supported brokerage when you are ready to trade.

Can I use Astral without risking real money?

Yes. You can research, build, and backtest strategies without connecting a brokerage or allocating funds. Real orders are only sent after you connect your own brokerage and choose to use live execution.

Does Astral hold my funds or execute trades?

No. Your cash and securities remain with your brokerage. Astral provides the workspace and sends approved orders to your connected broker; it does not custody assets or operate as a brokerage.

Which brokerages can I connect?

Astral supports a growing set of major brokerages through its connectivity partner. The current supported list is available on the Brokerages page and inside account settings.

What is included?

Astral unlocks the full workspace, including expanded research and strategy usage, backtesting, saved strategies, broker connections, alerts, paper trading, and eligible live deployments.

Can I try Astral for free?

No. Astral does not currently offer a free trial or free workspace access. After creating an account, you will be asked to subscribe before entering the product.

Can I change or cancel my subscription?

Yes. You can update your plan, payment method, or cancellation from the Stripe customer portal linked in your account settings. Access continues through the end of the current billing period after cancellation.
