What it shows

A fast answer to one useful question.

Several pairs laid on a low-to-high execution-cost spectrum with current and average markers. Comparative described statistics, not a customer’s fill cost or a recommendation.

Current + average spread across several pairs.
Ships a curated default set (XAUUSD, EURUSD, GBPUSD, USDJPY, AUDUSD); symbols= swaps it for up to five of the allowed instruments.
Renders inside a sandboxed Shadow DOM, so it cannot collide with your page’s CSS or scripts.

What the gateway serves itSIMULATED PREVIEW

Where it fits

Small enough for a sidebar. Useful enough for a homepage.

Spread Spectrum is a compact derived-data module rather than a full dashboard. It works best where you want one concise market observation with a clearly stated data basis.

Embed it

One script tag. No chart library. No build step.

Subscribe, authorize the domains that will host the widget, copy your public wk_ key, and paste the snippet where you want Spread Spectrum to render.

Subscribe & authorize domains

Your subscription includes 1 domain slot. Add more slots when the same widget needs to run on more sites.

Copy the public widget key

The wk_ key is meant to appear in the page source. It is restricted to the domains you authorize and can be revoked.

Paste the embed

Choose your theme and symbols, then drop the generated script tag into the page.

<script
  src="https://tickatlas.com/widgets/embed.js?w=spread-spectrum&k=wk_YOUR_KEY&symbols=XAUUSD,EURUSD,GBPUSD,USDJPY,AUDUSD"></script>

Light is the default, so the snippet stays clean. Dark appends &theme=dark; Auto appends &theme=auto and follows each visitor’s system preference. Picking one re-renders the preview above in that theme.

Embed parameters

Small configuration surface. Predictable output.

The querystring on the embed.js script tag stays intentionally compact. Most sites only need the widget slug, the public widget key, a symbol and a theme.

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.

Under the hood

Public embed key outside. Short-lived access inside.

The browser-facing key is domain-scoped by design. The embed exchanges it through our gateway, calls the hosted widget endpoint with short-lived authorization, and renders inside an isolated Shadow DOM.

CSS isolation

A sandboxed Shadow DOM with all:initial keeps your page’s styles and scripts out and the widget’s styles in. It fits its container’s width, never wider.

Domain authorization

The public wk_ key only renders on domains you add to the subscription, and you can revoke it from your dashboard at any time.

Cached refresh

It refreshes about every 15 seconds against cached data, so many visitors collapse onto one computation. Over the per-key / per-domain limit the gateway returns 429 and the widget keeps its last frame.

Graceful failure

No current data, a revoked key or an unauthorized domain all produce an explicit “unavailable” state — never a fabricated or zeroed value, and never a thrown error on your page.

Domain slot calculator

Each additional domain adds half the base price.

$9.99 per month

1 domain slot = $9.99 base subscription. Slots are fixed at purchase; manage domains and your key from your dashboard.

Data contract

The embed has a simple hosted endpoint behind it.

The embed calls this endpoint for you on each refresh, using a short-lived token minted from your wk_ key — your key never leaves the gateway.

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.
