Display the volume of 4 exchanges with BTC / USD pair in 100% stacked area chart.
The target exchanges are 3 companies that BitMEX refers to indexes (Coinbase, Bitstamp, Kraken). And I'm adding Bitfinex, which I think has a strong impact on the market.
If you uncheck the "100 Percent Stacked Area Chart", the volumes of each exchange will be displayed in piles.
