Micro Data-Viz

Candlestick Ticker

22 green/red candlesticks scroll left continuously, generating random OHLC data; a dashed last-price line with live label updates in real time.

When to use it

Finance dashboards, trading UI mockups, ambient data-viz backgrounds for fintech products.

When not to

Contexts needing real data — all prices are procedurally generated. Not suitable where motion competes with dense text content.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change UP color to '#00cfff' and DN color to '#ff9500', increase candle count to 30 (N=30), and slow scroll speed by changing 1100 to 1800. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • candle count (N=22)
  • scroll speed (acc/1100 threshold)
  • up/down colors (UP, DN constants)
  • price volatility (random spread *7)
  • canvas padding (padL/padR as W fraction)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • DPR-aware canvas resize
  • visibilitychange pause guard
  • prefers-reduced-motion freeze (shift=0 branch)
  • IIFE wrapper
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Price scale is normalized 0–100 internally — not real market data
  • Pointerdown resets chart entirely (init()) which may surprise users expecting click-to-pause
  • Background color hardcoded to #0a0f0d in CSS
