Signature

Label(key, opts) -> handle
A Label is a text annotation anchored to a specific bar index and price. Unlike Box text, a Label is not confined to a rectangle - it floats at the coordinate you specify.

​

const entryLabel = Label("entry", {
  x: 10, y: 42500,
  text: "Long entry",
  color: "#22c55eFF",
  size: 12.0,
  textAlign: "center",
});

​

Annotating pivot highs

onBar(() => {
  const ph = ta.pivothigh(ctx.high, 5, 5);
  if (na(ph)) return;

  const bar = ctx.i() - 5;
  Label(`ph_label_${bar}`, {
    x: bar,
    y: ph * 1.002, // slightly above the pivot
    text: str.format("{}", math.round(ph, 0)),
    color: "#ef4444FF",
    size: 11,
    textAlign: "center",
  });
