Aggregated Volume Indicator - Across biggest exchanges

This indicator allows you to view the total volume across multiple exchanges at the same time.
Currently, the indicator is pulling volume from these exchanges

• COINBASE
  
• FTX
  
• BINANCE
  
• BITFINEX
  
• KUCOIN
  
• KRAKEN
  

The script will pull data from coins that are available on those exchanges and sum up the volume.

Notes de version:

Fixed (Hopefully) the issue in previous release where some exchanges reported volume in $ instead of the coin.

Notes de version:

• Added a prediction of volume based on time-left in the current bar (shown more transparent)
  
• Cleaned up chart
  

Notes de version:

Fixed so that historical volume shows as well even if the underlying pairs don't have the historical data available.

Notes de version:

Removed all deprecated CoinBase USDC pairs
