Bitcoin Price Board

The Problem

Most Bitcoin price sites are either too sparse to be useful (just a number that updates every minute) or too overwhelming to glance at (every chart, every indicator, every news headline crammed onto one screen). Both extremes miss what most people actually want: a real-time price, a clean chart, and a way to know if something is moving without having to babysit the page.

Bitcoin Price Board is built for that middle ground. The price ticks live, the chart is fully featured when you need it, and a momentum gauge tells you at a glance whether the recent action is calm, climbing, or rolling over. If you want to be alerted when BTC crosses a number, set an alert and walk away.

What It Does

• Live BTC/USD price streamed from the Coinbase Exchange WebSocket feed, updating with every tick. The browser tab title and favicon update too, so you can see the price even when the tab is in the background
• Four chart styles (area, line, candlestick, OHLC bars) and twelve timeframes from 5 minutes to all-time, so you can zoom in on the last hour or zoom out to the whole price history
• Technical overlays: 50-period SMA, 200-period SMA, 21-period EMA, VWAP, Bollinger Bands, RSI, and Volume. Toggle each independently
• Momentum gauge that combines recent percent moves over multiple windows with the green-to-red 1-minute candle ratio and position in the recent range. Describes what just happened, not what will happen
• Customizable price alerts with browser notifications and an audio chime. Type a price, the site figures out if it is above or below current and watches for the cross
• Drag-and-drop card layout so you can arrange the dashboard the way you actually use it. Layout persists in your browser
• Three themes: light, dark, and OLED-darker, all with full color contrast
• Installable as a PWA on iPhone, Android, or desktop, so it lives alongside your other apps and opens in its own window

How It Works

Live ticks come straight from the public Coinbase Exchange WebSocket feed, the same one most reputable price aggregators use. Historical candles for the chart and the all-time high are fetched from the public Coinbase Exchange REST API. There is no middleman server, no API key, and no proprietary feed in between.

Privacy and Data

Bitcoin Price Board runs entirely in your browser. There are no accounts, no analytics scripts, no tracking pixels, and no server-side logging. Your theme choice, card order, alert list, and sound preference are stored only in your own browser using localStorage. Close the tab and the only thing that persists is what is on your own device.

If you also like to keep an eye on traditional markets-style data, the Gas Map is built on the same principle: live data, no signup, no fee.
