For your IT team

One page, no surprises. Dynamo Ticker makes outbound HTTPS connections on port 443 only. It needs no inbound port, no VPN and no firewall exception.

Checked against release 3.6.9.

Direction and protocol

All connections are made by the ticker PC, outbound, over TLS on TCP 443, with normal certificate validation. Nothing connects in from the internet. If your proxy or inspection appliance needs a trust configuration for these hosts, that is handled with you; the software never bypasses certificate checks.

Hosts to allow

Host Purpose
licensing.dynamo-led-displays.co.uk Licence renewal, add-ons, signed software updates, weather and AI backgrounds (add-ons), and phone control from outside the building (add-on). One host for everything Dynamo.
widgetdata.tradingview.com (secure WebSocket) Live quotes and chart history for the market cards.
symbol-search.tradingview.com The symbol search box in the control window.
s3-symbol-logo.tradingview.com Company and currency logos on the market cards.
The news and RSS feed hosts your site configures Headlines. Plain HTTPS GET of each feed address, and of the picture hosts named inside those feeds.
checkout.stripe.com Only when someone buys an add-on, and only in the operator’s own browser or phone, never from the ticker software.

If a site does not use market cards, the three market-data hosts can be left closed and prices will simply not show. If a site does not use news, no feed hosts are needed.

What is not required

  • No inbound port. There is nothing to forward and nothing to open on the perimeter.
  • No VPN. Phone control from outside the building goes out through the licensing host on the same outbound 443 connection.
  • No local port on the internet. The software uses a local helper on port 3000, bound to the PC’s own loopback address only. It must never be exposed and never needs to be.
  • Local control panel, optional. If the site chooses control from a browser on the local network, the PC listens on the LAN on port 8800 by default (changeable), pairing-code protected, private addresses only. This is off by default and is never reachable from the internet.

What is sent

Licence renewal sends the device’s signed licence, a device identifier derived one-way from the Windows installation, the software version and a random nonce. The weather add-on sends the site’s location rounded to about one kilometre. The AI add-on sends the words the operator typed. Market cards send the symbol names. Nothing about the people who see the display is collected: no camera, microphone, audience measurement or analytics. The full statement is in the privacy notice. → Privacy

What happens if a host is blocked

  • Licensing host blocked: the band keeps playing for the rest of its seven-day lease, with a notice on the band 48 hours before expiry; it never quits. Restore the connection and it renews.
  • Market-data hosts blocked: prices stop updating and the last values stay.
  • Feed hosts blocked: the last fetched headlines keep scrolling.

The PC

Windows 64-bit. The installer is verified by SHA-256 on the download page; updates after that are signed by Dynamo and verified on the PC before install, in a night window the site chooses, with automatic rollback. Dynamo’s display protection sets local Windows policy for updates, sleep, notifications and start-up; a domain Group Policy setting the same value always wins, and every change can be reverted in one step. → Operator guide
