Check the local CDP connection (127.0.0.1:9222) to TradingView Desktop and return current chart state. Local-only: performs no external network requests.

Get current chart state (symbol, timeframe, chart type, indicators)

Change the chart symbol

Change the chart timeframe/resolution

Zoom the chart to a specific date range (unix timestamps in seconds). Pages in older history as needed, so this also serves as jump-to-date for reviewing a past trade: pass a window around the trade time.

Get OHLCV bar data from the chart. TWO MODES: pass from+to (unix seconds) to get bars from THAT window — required when reviewing a past trade, because without it you get the newest bars regardless of where the chart is navigated. Omit both for the newest count bars. A window with no loaded bars is refused rather than answered with the latest data; call chart_set_visible_range for that window first. Defaults to summary=true (compact stats + last 5 bars).

Take a screenshot of the TradingView chart. Saves to the fixed generated/screenshots/ directory with a program-generated name and returns the path. No path or name input is accepted.
