BTC ETH Tracker shows Bitcoin, Ether and the ETH/BTC ratio in US dollars or pounds, with charts that go back to 2012. It is for reading the numbers. It does not trade, and it does not tell you what to do.
What it does

Where do the prices come from?
Public price services. Each screen lists its data sources, with credit to each provider.
