Same symbol card as Symbol Overview, with live auto-refresh every 60 seconds — Pro plan.

Charts HMAC signed

Live sample Open fullscreen

Preview is static. Production polls /widgets/api/live_overview every 60s with your API key (HMAC is for the iframe load).

Embed code

HMAC signing

Build message = api_key + t + lang then
token = HMAC_SHA512(secret_key, message).hexdigest()
t is UTC unix time in milliseconds and must be within 15 seconds of the server clock. The signed URL must include the same widget parameters as the embed iframe above.

Tips

Use HTTPS pages for iframes. For production, allowlist your domain in the console and set enforce_domain=T on the key. Local file:// tests often send no Referer — add &domain=localhost to the iframe URL and allowlist localhost in the console. HMAC t/token expire in 15 seconds: regenerate immediately before opening the page.
