CoolTick: Lightweight Stock Ticker for Investors

CoolTick — Customizable Stock Ticker for Your Dashboard

What it is

• A lightweight, embeddable stock-ticker widget that displays live prices, percentage changes, and simple charts for selected symbols.

Key features

• Custom symbol list (add/remove, reorder).
• Live updates (configurable refresh interval).
• Display modes: horizontal scroll, compact list, or marquee.
• Color-coded changes (green/red) and optional percent/absolute values.
• Simple sparkline or mini-chart per symbol.
• Theming: choose font, size, background/transparency, and accent color.
• Responsive layout for dashboards and mobile.
• Keyboard-accessible controls and ARIA labels for basic accessibility.
• Lightweight: minimal JS/CSS footprint and lazy-loading.
• Export/import symbol presets (CSV/JSON).

Typical use cases

• Personal finance dashboards (homebrew or SaaS).
• Investor blogs or news sites showing market movers.
• Intranet/company dashboards displaying portfolio or index watchlists.
• Trading setups needing a compact, always-visible price strip.

Integration & tech notes (assumed defaults)

• Embeddable via a small JS snippet that mounts into a container element.
• Uses WebSocket or polling REST API for price data; supports pluggable data adapters.
• Graceful offline behavior: cached last values and a “stale” indicator.
• Config stored in localStorage with optional sync via user backend.
• Configurable CORS-friendly endpoints; supports API key injection via server proxy (avoid exposing keys client-side).

Configuration options to offer users

1. Symbols: add, remove, reorder.
2. Refresh: real-time (WebSocket), 5s, 15s, 60s.
3. Display: show percent, change, last trade, volume, sparkline.
4. Theme: light/dark, accent color, font size.
5. Behavior: scroll speed, wrap/no-wrap, pause on hover.
6. Accessibility: reduced motion, high-contrast mode, readable labels.
7. Data source: choose provider and input API key (with server-proxy recommended).
8. Persistence: local-only or save to user account.

Monetization & tiers (example)

• Free: basic symbols, polling every 15–60s, limited theming.
• Pro: real-time updates, unlimited symbols, advanced charts, presets export.
• Enterprise: white-labeling, on-premise data connectors, SLAs.

Implementation checklist

• Define minimal public API for embedding and config.
• Build modular data-adapter layer (WebSocket + REST).
• Implement secure server proxy pattern for provider API keys.
• Design responsive UI variants and theme tokens.
• Add accessibility audit and keyboard navigation.
• Add analytics for errors/uptime (privacy-conscious).
• Write docs and quick-start embed snippet.
