As you can see, this script plots the current (10-min. delayed) CME Futures price versus Bitfinex, Bitstamp, and Coinbase prices.
It's displayed here on a 30 minute view because at the time of writing the futures have been alive for approximately one day. The script will likely be more useful on longer time frames as a macro-level indicator.
It's pretty simple to adapt this to additional exchanges
