All candlestick styles

Every style rendered live — each is just a different set of property values on the same component, and each has its own page with a dedicated preview, use cases and API example.

MinimalAxis and grid hidden — just the candles, for a clean inline price spark.

DarkLight candles on a dark canvas — the classic trading-terminal look.

Use cases

What developers typically build with the candlestick component.

Daily market-recap images auto-posted to social
Crypto price snapshots for newsletters and alerts
Trading-journal and portfolio report graphics
Watchlist cards with a fresh price chart per ticker

Use it dynamically via the API

Push a fresh OHLC array per render with '<key>.candles' (or just '<key>'); labels and colors are overridable too.

Frequently Asked Questions

Send '<key>.candles' as an array of { open, high, low, close } objects — one per period — plus '<key>.labels' for the dates.

Yes — upColor styles bullish candles (close ≥ open) and downColor bearish ones; wickColor overrides the high-low line color.

The candles render the OHLC price bars; a separate chart or metric component can show volume alongside on the same canvas.
