Lists the built-in indicators with their ids, names and where they draw (overlay: on the price pane; panel: in a pane of their own). Search by words of the id or name ("moving average", "bollinger"). Use the id with chart.addIndicator(id, params); get_indicator has the params and line keys.

One built-in indicator in full: its default params (what addIndicator takes), its inputs, its lines (the keys getIndicatorOutput returns per bar, which are often not the indicator id: RSI's line is value), its levels, and code that adds it and reads it. Takes the id, the short name or the full name.

Lists the built-in drawing tools: the type that chart.addDrawing and chart.setDrawingTool take, the number of points (anchors) each needs, how the pointer draws it, and the options it offers. Search by words of the type or name ("fib", "channel").

Lists the options that new ChartWidget(el, options), new Chart(el, options) or new ChartWidgetGrid(el, options) take: each name, its TypeScript type, its doc, and the values it allows where it allows only some. Search by words of the name or doc.

Lists the names ChartWidget's features option takes (every switch is on unless set false). A name without a dot turns a whole capability off ('alerts', 'hotkeys'); a dotted name, one place ('toolbar.screenshot', 'menu.chart.settings'). Narrow by a prefix.

Lists the style keys of the chart's look and the kind of value each takes (color, boolean, lineStyle: 'solid' | 'dashed' | 'dotted', width: pixels up to 20). They go in Chart's overrides option or chart.applyOverrides({...}). Narrow by a prefix such as 'grid.' or 'series.candlestick.'.

Checks an options object before it goes to new ChartWidget, new Chart or new ChartWidgetGrid: unknown option names (with the one likely meant, and where an option of another entry point belongs), values outside the allowed ones, numbers given as strings, intervals, feature switch names, style override keys and values, and languages, nested options included. Write functions and adapters as strings; they pass.
