/// The Daily Factor Indicator was created by Andrea Unger (Stocks and Commodities Jun 2023 pgs 26-31), and this is a new volatility indicator
/// that compares the body, which is the absolute difference between the previous open and previous close, and the range which is the difference
/// between the previous high and previous low. The indicator is calculated by dividing the body and range to determine the volatility for the
/// previous bar. This indicator will range between 0 and 1. Values closer to 1 mean very high volatility, and values closer to 0 mean very low
/// volatility. I have introduced an EMA to decide buy or sell signals and colors. Darker colors mean the indicator is
/// above the threshold level, and lighter colors mean the indicator is below the threshold level. Colors are shades of green when the price is
/// above the moving average and shades of red when the price is below the moving average. Feel free to try out your own threshold level and
/// general buy and sell signals.
