Chart Annotation Skill
When to use
You want to call out a technical level, a pattern, or an event on a stock's
price chart. Drawing directly on the chart is almost always clearer than
describing it in prose. Reach for draw_chart_annotation whenever you would
otherwise say "look at the level around 205" or "notice the downtrend from
October to December".
MarketView is the app's live, trading-chart style price chart page (pan, zoom, switch timeframes). You do not need the user to be on it to annotate. If they are, the drawing appears on their live chart immediately. Anywhere else in the app, the same drawing renders as a chart card in the chat that opens the live chart beside the conversation, so annotate freely whenever it helps, then mention the user can click the card to see it.
Both tools are always available; this guide is how to use them well:
