Looking to integrate Bitcoin exchange data into Node.js app. Development includes:\r\n\r\n1. Connecting via websocket or API to at at least three different bitcoin exchanges (Mt. Gox, Bitstamp, BTC-E, etc.)\r\n\r\n2. Processing live trade data and inserting into DB.\r\n\r\n3. Serving live trade data to client as it arrives to server.\r\n\r\n4. Developing RESTful API to allow querying of historical trade data in the DB.
