# Trades tape

A React component in [Beamline](https://beamline.io/)'s [Trading](https://beamline.io/components/trading) category. Live demo: https://beamline.io/components/trades-tape

Recent trades, newest first, with side glyphs, large-print marking and one-time arrival flashes.

## Use it for

- Beside the order book to show what is actually trading.

## Not for

- The user's own fills → a [data-grid](https://beamline.io/components/data-grid) or positions view.

## Anatomy

- header (title, stale chip)
- column headers
- row (▲/▼ + price in side colour, size, time)

## Variants

- **density**: compact (20px rows), default (24px), comfortable (28px)
- **time**: clock, relative

## States

- live (new prints flash once in place)
- large print (side-tinted row, bold size)
- stale (caller's chip in the header; prints stay)
- empty
- Density: explicit instance prop, then scoped component default, then managed root density; omitted static-scope density stays inherited. Changes keep row identity and focus.

## Keyboard

- Read-only table; no interactive parts.

## Motion

A new print tints its row in its side's colour and fades over 600ms; rows never slide, so the eye stays on the numbers. Reduced motion: no fade, prints still arrive.

## Props

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `trades` (required) | `Trade[]` | — |  |
| `largeSize` | `number` | — |  |
| `limit` | `number` | `30` |  |
| `priceDecimals / sizeDecimals` | `number` | — |  |
| `time` | `'clock'\|'relative'` | — |  |
| `stale` | `ReactNode` | — | Caller-owned stale description ("Stale · 12s"), shown as a warning chip with a clock in the header. |
| `density` | `'compact'\|'default'\|'comfortable'` | — | Row height 20 / 24 / 28 px (the order book's metrics). Omitted: follows the nearest scope's density; an explicit value wins. |
| `style / ref` | `CSSProperties / native Ref` | — |  |
| `classNames` | `TradesTapeClassNames` | — |  |
