BTC World Volume (Multi-Exchange)

Release: 2018-03-29

__________________________
WHAT IT DOES

Bitcoin is listed on multiple exchanges. Many people have called for a single global index that would quote BTC volume across all exchanges: this script is such a virtual volume aggregate of the 17 largest fiat exchanges on TradingView (listed in the script comments, and in Format > Inputs for you to select). It includes USD, EUR, JPY, KRW and USDT sources.

It will, independently for each tick, quote the volume from all selected exchanges and display a stacked representation, freely inspired from CoinMarketCap charts; also a Moving Average. Each fiat/continent has its own general color, to be able to quickly glance at where volume is coming from, e.g. BitMEX or Asia. (colors are based on Google's Material Design).

By default:

• Grey: BitMEX
  
• Green: USD
  
• Yellow: Tether (USDT)
  
• Red: Asia (JPY, KRW)
  
• Blue: Europe (EUR)
  

No more "on Coinbase this" or "on Bitstamp that", you've now got a global overview! It becomes easy to debunk a few common myths.

See CoinMarketCap for reference.
Note: Bitmex is not taken into account in CoinMarketCap (afaik) since it's trading a derivative asset (XBTUSD contracts), but it usually amounts to ~50% of the overall BTC volume in USD value. The 16 other exchanges quote their volume in BTC, and they represent 30~40% of the overall BTC volume. I believe the whole is good enough to smooth out exchanges variations, and get a fair representation of real-time activity.

HOW TO USE IT

Just add it to your chart, it will appear as a separate indicator. By default, it appears as stacked colored "areas". There is also a total volume Histogram, which is transparent by default: you can tweak that in Format > Style.

The darker and lighter backgrounds are respectively indicative of a downward price candle (open > close), or an upward price candle (close > open). They are unrelated to volume and simply help interpreting the indicator.

• You can check/uncheck exchanges in the Format > Inputs tab to remove/add some of them from computation. All are enabled by default.
  
• You can check/uncheck exchanges in the Format > Style tab to hide them (usually you would hide all or none).
  
• You can edit colors and transpareny as well for each exchange.
  
• You can edit "Volume histogram" transparency to have it show (it's a simpler representation than areas).
  
• Moving Average: You can select the type (SMA, EMA, DEMA or TEMA) and length.

Minor improvements to the code.
________

1. Changed transparency of all plots to 0 (i.e. fully opaque), except the first (BitMEX).

2. Re-ordering of plots in Format > Style, hopefully easier to navigate.

3. Histogram bars (Total Volume) are now thicker. Still hidden (fully transparent) by default.

4. Better descriptions in Format > Style:

• "Total Volume" (was formerly "Volume Histogram").
  
• "Background: Price Down (Color 0) or Up (Color 1)" (was formerly "Background").
  
• "Moving Average" (was formerly "plot").
