ui

rt.setUi draws strategy state on the instance. Pass a full description each time. The platform replaces the previous one.

Field	Contents
cards	Metric cards. kind is metric, with id, label, and value
charts	A line. id, label, and points of time and value
fields	Read-only fields. id, label, and value
buttons	Buttons. id and label. danger: true asks the platform to confirm again

The strategy supplies label and value. The platform does not translate copy the strategy wrote. Do not rely on button text alone for a dangerous action. A danger button gets a second confirmation.

rt.setUi({
  cards: [{ kind: "metric", id: "px", label: "最新价", value: ticker.last }],
  charts: [],
  fields: [],
  buttons: [{ kind: "button", id: "stop", label: "停止", danger: true }],
});
