Pre-built
The library that ships with the platform — classic indicators, ready to add. Every one of them is open in Indie®.
Marketplace
Indicators published by the community, free or paid.
Your own
Write it in Indie® — by hand, or with the AI assistant doing the typing.
Strategy tester
Indicators that place orders are strategies — run them against history before trading them.
Add an indicator to a chart
Open the ‘f’ icon in the chart’s top control panel — it gives you both the pre-built library and the marketplace. Pick an indicator and it is applied to the active chart.Use an indicator from the marketplace
All published indicators live in the Indicator Marketplace, where you can filter by Free and Paid. Free and already purchased indicators have an Add to Chart button, so you can apply one without leaving the marketplace page. If you would rather have an LLM pick for you, the MCP server can search the marketplace from your AI client.Configure what you added
Every applied indicator has a gear icon next to its name above the chart; for oscillators the same icon sits below the chart area. Inputs, styles and visibility all live there. Indicator settings →Build your own
When nothing in the library fits, write the indicator yourself in Indie® — the platform’s own language, close to Python:- Indicator code editor — the built-in IDE, with Add to Chart to test what you wrote.
- Indie® language — syntax, data model, library reference and code examples.
- AI Assistant and the MCP server — describe the idea in plain words, convert scripts from other platforms, or have the code validated for you.
