This indicator shows correlation strength between the source asset plotted in the main chart and a user-input asset in the indicator panel. For example, if the main chart panel is displaying BTCUSD and the correlation indicator is NDX, then the correlation strength is plotted as the relationship between the two. A strong positive correlation target is set at 0.80 but can be changed. A strong negative correlation target is set at -0.80 and can also be changed.
The indicator also has an option for a plot of the ta.correlation() function for a reference line.
