Bitcoin Relative Value Indicator

This script retrieves the close price data for Bitcoin, DXY, CPIAUCSL, M2 money supply, and SPX and calculates the average of the four data points. It then calculates the relative value of Bitcoin by dividing the Bitcoin close price by the average of the four data points. The script determines whether the relative value is increasing or decreasing and plots the relative value on the chart using a green line if it's increasing and a red line if it's decreasing.
