This is a script that allows you to plot recessionary periods over your charts. This gives you the context between different recessions classified by different institutions over prior periods.
Currently, the indicator allows for the display of shaded periods for the following:
NBER Recessions (Peak through Trough (as seen on FRED charts))
NBER Recessions (Period following the Peak through the Trough)
OECD Recessions (Peak through Trough)
At the moment, all the recessions are for the United States only, this can change over time as more datasets are added.
