.BXBT Index

The current .BXBT index weighted as close as possible to BitMEX's with updates as BitMEX refreshes their index.
Difference between this and the script titled '2020 March 27 .BXBT Index': this one will receive updates because it doesn't have a date in its title.

ItBit's weight is combined with Gemini's due to ItBit not being on TradingView as of now. BITTREX:BTCUSD substituted with BITTREX:BTCUSDT*POLONIEX:USDTUSD to backfill because Bittrex only recently (late 2018) started to offer a fiat BTC/USD pair. Not that it matters since the index used in 2018 didn't include Bittrex if I remember correctly.
