A platform that knows how you trade,
and builds what you need.
Training wheels for your setups
Write your setup down as a playbook, then tick what you saw on every trade you take. Stay faithful to it, and the model learns which conditions get you to your targets and shows those odds the next time they appear. A backtest fills it quickest.
Your workflow, built in plain words
Bring your accounts and the way you work. The agent builds what's missing around them: indicators, studies of your setups, and views on your trades, days and playbooks. You approve every piece before anything uses it.

How usage works
Your plan covers the terminal and broker accounts. AI is billed separately as you go.
Broker accounts
Each plan includes how many live MT4, MT5 and cTrader accounts you can keep connected at once. You can link, rotate, and change accounts as often as you want — disable a live account to free a slot for another. Demo accounts are always free and unlimited.
- Live accounts — how many can stay connected at the same time
- New account links — unlimited; disable one to enable another
AI agents
Plans do not include AI credits. When you run an agent, usage is deducted from your balance — top up anytime, no monthly allowance to track.

Questions & answers.
Pricing, brokers, credits, the terminal, studies, and how the platform works.
Not financial advice. Chartnaut does not provide trading signals or predictions. Analytics are descriptive and based on your own data.
Yes. You can use Codex or Claude Code natively in Chartnaut, or through the Chartnaut MCP. You choose which.
Download the Chartnaut desktop app. Open AI Providers. Chartnaut shows that page only in the desktop app. Follow the instructions on that page. An Agent in Chartnaut then uses that subscription, so you do not spend Chartnaut AI credits. The Agent stays in Chartnaut beside your charts, studies and trades.
If you already work in Codex or Claude Code, connect the Chartnaut MCP and those tools can work with your Chartnaut account from there.
