A demo trading visualisation using Go and React
This app comprises a backend order book, price ticker and WebSocket interface - written in Go - to power a simple UI visualisation - written in React.
The backend service connects to a firehose of currency exchange prices (via GDAX public price feed) and broadcasts those ticks over a websocket to any subscribed client. Clients sample those ticks to show the current ask price and volume on an animated scale.
To subscribe to a currency pair, the client sends a message in the following format:
client.subscribe("BTC-USD");
