The data contract
This widget reads only public market data through our hosted gateway — no account data, no order book, no personal data.
The gallery and this preview run in SIMULATED mode — synthetic shapes, no key, no network. Live data flows only after checkout, on your authorized domains.
Embed it
- Subscribe from your dashboard and add the domains you'll embed on.
- Copy your public
wk_key from the widget panel. - Drop the snippet below into your page, swapping in your key and symbols.
<script src="https://tickatlas.com/widgets/embed.js?w=spread-spectrum&k=wk_YOUR_KEY&symbols=XAUUSD,EURUSD,GBPUSD,USDJPY,AUDUSD"></script>Default is light — the snippet stays clean. Pick Dark or Auto (Auto follows each visitor’s system theme) to append &theme= and preview it live.
Embed parameters
The querystring on the embed.js script tag above.
| Parameter | Type | Required | Description |
|---|---|---|---|
| w | string | Yes | Widget slug — fixed to “spread-spectrum” for this widget. |
| k | string | No | Your public wk_ key. With it the widget goes live on your authorized domains; omit it for the SIMULATED preview (synthetic data, zero network). Default: preview mode. |
| symbols | symbols | No | Comma-separated symbols to display (max 5; extras are dropped), each within the widget’s allowed set. Omit for the widget’s curated default set. Allowed: BTCUSD, XAUUSD, EURUSD, GBPUSD, USDJPY, AUDUSD, USDCHF, USDCAD, NZDUSD, ETHUSD. Default: XAUUSD,EURUSD,GBPUSD,USDJPY,AUDUSD. |
| mode | enum | No | Force preview even with a key, e.g. for a staging page. Allowed: live, preview. Default: live when k is present, else preview. |
| theme | enum | No | Colour theme. light (default) is today’s look; dark uses a WCAG-AA dark palette; auto follows each visitor’s system (prefers-color-scheme). Omit for light. Allowed: light, dark, auto. Default: light. |
The wk_ key is public by design —
it only works on the domains you authorize, and you can revoke it any time from your dashboard.
Data endpoint
The embed calls this hosted endpoint for you on each refresh, using a short-lived token
minted from your wk_ key —
it never carries your key to the browser. These are its parameters and the values this widget uses.
Endpoint parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
| symbols | symbols | No | Comparison widgets: comma-separated symbols. Its presence selects the multi (assets[]) response. Allowed: BTCUSD, XAUUSD, EURUSD, GBPUSD, USDJPY, AUDUSD, USDCHF, USDCAD, NZDUSD, ETHUSD. Default: XAUUSD, EURUSD, GBPUSD, USDJPY, AUDUSD. This widget pins it to its full configured set. |
| period | enum | No | Window for the average / min / max / stddev spread statistics. Allowed: 1h, 24h, 7d, 30d. Default: 24h. This widget pins it to 24h. |
This widget renders the symbol set configured for it, so its embed takes no
symbol — it always
requests its full allowed set: BTCUSD, XAUUSD, EURUSD, GBPUSD, USDJPY, AUDUSD, USDCHF, USDCAD, NZDUSD, ETHUSD.
Response
Every response is a JSON envelope { success, widget, cached, data }.
The data object for this widget:
Good to know
- Theming & isolation
-
The widget renders inside a sandboxed Shadow DOM with
all:initial, so your page's CSS and scripts can't reach in and its styles can't leak out. It fits the width of its container — never wider — and brings its own light palette. - Refresh, caching & limits
-
It refreshes about every 15 seconds against cached data, so many visitors collapse to one
computation on our side. Requests are rate-limited per key and per domain; over the limit the
gateway returns
429and the widget simply keeps its last frame until the next tick. - When data is unavailable
- If a symbol has no current data, the widget shows an explicit “unavailable” / “no data” state — never a fabricated or zeroed value. A revoked key or an unauthorized domain leaves the widget in that same state; it never throws on your page.
- Pricing & domain slots
- Billed monthly per domain slot. The base ($9.99/mo) covers one domain; each extra slot adds half the base. Slots are fixed at purchase — cancel any time and the embed stays live to the end of the paid month, then stops.
