Crypto Market Monitor

The goal of the Crypto Market Monitor Project is to make market data more accessible. One challenge to anyone wishing to do anything with bitcoin market data (and any other cryptocurrency data), is the variety of markets. Each has their own api and data format. The Market Monitor project makes it easy to get data from many exchanges from one source in a standardized format. We are planning on adding support for additional exchanges, and additional currency pairs in the near future.

For example usage, see [btc.marketmonitor.io] (http://btc.marketmonitor.io)

See [Broadcast Server] (https://github.com/CryptoMarketMonitor/BroadcastServer) to connect directly to the data with Socket.io.

If there is any data you'd like to see added or any comments or critiques of our current data streams, please open an issue. We are always looking for feedback and any improvements we can make.
