BTC Pair Change %

This script makes it easier to quickly check how the BTC pair of the current symbol is performing on any pair.
It adds a "change percentage widget" (of the BTC pair) to the top right of the chart.
(Refer to the image for an example.)

The change percentage calculation is performed as described here:

• www.tradingview.com/...-filters-calculated/
  

To match the "Chg%" that appears on TradingView watchlists, a 24H (1440min) timeframe is used, as described here:

In short, this script:

• Searches for the BTC pair of the current symbol
  
• Calculates the change % using the above described logic (links)
  
• Adds a "change percentage widget" (of the BTC pair) to the top right of the chart
  
• Allows for using 24H timeframe or the current timeframe (enable "Use current timeframe" under the script options)
