Changelog

​

Added

• Live data feeds. sources.DataFeed(url, stale_after=...) streams typed records from your own server into @data_context callbacks and request_series, next to the CSV path that shipped in v5.18.0. The launch history settings warm the series up from recent records, reconnects after platform-side interruptions are healed from a recent-record buffer on a best-effort basis, and a launch with a date range computes over the window and finishes. See Live data from a feed.

​

Added

• Dictionary containers. dict[K, V] is now a built-in container type: assign, read, and delete items by key, get the item count with len(), and take snapshots of the contents with keys() and values(). Keys can be str, int, bool, or finite float, and containers can be nested — a dictionary value may hold another dictionary, a list, an Optional, or a tuple pair.
• External data sources. Use your own data in indicators: point sources.Csv at a public HTTPS CSV file and read it as candles with @sec_context, as typed rows with @data_context, or directly with request_series. Indicators that use external data cannot be published to the Marketplace. See External data.

​

Added

• Table drawings. Build tables on charts with Table, TableRow, and TableCell from indie.drawings.

​

Added

• Manage Indie scripts from AI. New MCP tools let the AI create, read, update, and run your Indie scripts directly — so you can build and edit indicators from a chat instead of switching to the IDE.
• Manage alerts from AI. New MCP tools give the AI full control over alerts — create, read, update, and delete them, turn them on or off, preview before saving, inspect their schema, and review trigger history — all from a conversation.
• Richer alert messages. An alert message can now reference any plot of an indicator used in the alert, not just the series directly involved in the condition — so notifications can include more of what the indicator calculates.
• Simpler MCP sign-in. The MCP server now authenticates with your existing TakeProfit platform account — no separate API keys or credentials required.

​

Added

• Light theme support in the IDE widget.
• Indicator recovery: if a calculation error occurs, the indicator now recovers gracefully and shows available history with a refresh button, instead of crashing.

​

Fixed

• Fixed the save function in the IDE.

​

Added

• Context.calc_on now supports requesting data from lower timeframes than the current chart. Previously only higher timeframes were supported.

  • TakeProfit_SearchMarketplaceIndicators: search community indicators in the Marketplace — LLM can now recommend indicators by description.
• MCP OAuth authentication through TakeProfit platform account.
• MCP back-to-back endpoint enabling MCP tools to be used from the AI Chat without additional auth setup.
