Prediction market

Strike / threshold line with switchable horizons:

<LiveChart
  data={data}
  value={value}
  theme="light"
  color="#3b82f6"
  formatValue={(v) =>
    v.toLocaleString(undefined, { maximumFractionDigits: 0 })
  }
  referenceLine={{ value: 100_000, label: "Strike" }}
  windows={[
    { label: "1m", secs: 60 },
    { label: "5m", secs: 300 },
    { label: "15m", secs: 900 },
  ]}
  windowStyle="rounded"
  onWindowChange={(secs) => console.log(secs)}
/>

Polymarket-style prediction line. "Will Bitcoin stay above $67,500?"

The button bar starts on the first option (1m). Keep more history than the longest window so switching horizons stays meaningful.

Inspired by Polymarket-style short windows on an underlying price.
