Viral Force Index

Based on the Elder Force Index (EFI) indicator, the Viral Force Index (VFI) attempts to normalize the original indicator by plotting EFI on the interval ]-100, 100[.
VFI comes with a bar coloring feature, allowing users to get an idea of the current value of the indicator without having to look away from the chart.
Additionally, the linear regression line provides a simple way to filter out the noise with little to no additional 'lag'.
