TradingView Communication

Use this to avoid re-discovering the bridge between the OneKey app repository and the separate TradingView chart repository. Do not assume fixed local filesystem paths; locate files by symbol names with rg.

Mental Model

The app loads the chart app inside WebView/iframe and both sides exchange plain message objects.

• Chart -> app: $private payloads with scope, origin, method, and data.
• App -> chart: webRef.current.sendMessageViaInjectedScript(message), which lands in the chart as window.postMessage(message).
• Web/extension uses iframe postMessage; native/desktop injects a script that calls window.postMessage(...).
• Market mode data normally comes from the OneKey app/background service. Perps/Hyperliquid candles are fetched by the chart app directly, while marks, price scale, symbol sync, and chart lines still use the app bridge.

Search Anchors

Start with rg instead of assuming local paths.
