Features

From question to working strategy.

Ask, build, test, inspect, and run without changing tools.

01 / Ask

Build through conversation.

Describe the setup. Astral asks what matters, then writes a strategy you can inspect with research still open.

02 / Inspect

Inspect the generated code.

Review the generated strategy. Entries, exits, sizing, and risk stay in the same editor as the backtest itself.

03 / Test

Test in the same workspace.

Run the strategy in the full backtest panel. Equity, comparisons, and metrics stay with the rules you just wrote.

04 / Measure

Read the full result.

Compare return and risk, inspect the equity path, and review every completed trade before the next run.

05 / Operate

Watch the market and activity.

Keep the watchlist, alerts, fills, and strategy status together in one dashboard after you finish testing.

Astral MCP

Bring Astral into the AI you already use.

Connect ChatGPT, Claude, Cursor, Codex, Gemini, or any compatible MCP client with one secure endpoint.

MCP workflow

Ask your AI. Astral does the work.

Your AI interprets the request, calls the right Astral tool through MCP, and returns an interactive result you can inspect and continue working from in the same conversation.

ChatGPT

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.
