Plots lines of June and Sept. Includes Index (BXBT) and an optional line to show the average of seven exchanges.
Those seven exchanges are:
(BINANCE:BTCUSDT+POLONIEX:BTCUSDT+BITTREX:BTCUSDT+BITFINEX:BTCUSD+BITSTAMP:BTCUSD+COINBASE:BTCUSD+OKCOIN:BTCUSD1W)/7")
I plan on adding a switch to switch off the prices and show premiums. I may just make a different indicator for that.
