What it shows

A fast answer to one useful question.

A compact momentum scanner: each covered symbol plotted by its H1 RSI so a page can show where short-term pressure is building across a small watchlist.

  • H1 RSI scan · several symbols.
  • Renders its full configured universe, so the embed carries no symbol list.
  • Renders inside a sandboxed Shadow DOM, so it cannot collide with your page’s CSS or scripts.

Where it fits

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

Signal Radar 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 Signal Radar 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, then drop the generated script tag into the page.

Widget theme 
<script
  src="https://tickatlas.com/widgets/embed.js?w=signal-radar&k=wk_YOUR_KEY"></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 “signal-radar” 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.
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.

Full covered universe

This widget renders its whole configured scope, so the embed ships no symbols=.

Themes

Light is the default; dark and auto are query-string switches.

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.

YOUR PAGE embed.js wk_ key + domain TICKATLAS Widget gateway domain check · token mint HOSTED ENDPOINT signal-radar cached market data RENDER Shadow DOM isolated styles ~15 second refresh · cached reads · per-key / per-domain rate limits · last verified frame held through temporary gaps
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.

Each additional domain adds half the base price.

$14.99 per month

1 domain slot = $14.99 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 One or more comma-separated symbols, within the widget’s allowed set. Returns each symbol’s quote plus its H1 RSI_14. Allowed: BTCUSD, XAUUSD, EURUSD, GBPUSD, USDJPY, AUDUSD, USDCHF, USDCAD, NZDUSD, ETHUSD. This widget pins it to its full configured set.

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.

Frequently asked

Before you embed it.

What the widget reads, how preview mode works, and what happens when data is temporarily unavailable.

Which symbols does it show?

With no symbols= parameter it renders the full covered universe: BTCUSD, XAUUSD, EURUSD, GBPUSD, USDJPY, AUDUSD, USDCHF, USDCAD, NZDUSD, ETHUSD.

Can I narrow it?

Yes, pass symbols= as a comma list (max 5) from that same allowed set.

What is plotted?

Each symbol's H1 RSI_14 — a scan of short-term pressure, not a forecast or ranked recommendation.

How often does it refresh?

~15-second cached poll; the last verified reads are held on a feed gap.

Does it need a key to preview?

No, the preview is synthetic and keyless; live embedding is a paid subscription.
