Hanover's PSA Indicator Update :

Updated Aug 26, 2018 — I have made two enhancements (download the new version in the link below):
1. If you enter an asterisk (*) as the second parameter of HighlightPairs, the current chart's pair will be highlighted in the list displayed by PSA.
2. New parameter setting: SmoothnessMultiplier.
 If set to 0, PSA operates as it did before.
 If set to a positive (>0) value, PSA will calculate a standard deviation of all of the regression line slopes, in an attempt to establish which is the smoothest (as opposed to steepest) trending pair. Each of these values is then multiplied by your SmoothnessMultiplier value, before being displayed as an additional column at the right of the list (sorry, there is currently no facility to sort the list by the values in this column). If you use RescaleUsingATR, the slope values are likewise rescaled before their standard deviation is calculated. The lower the standard deviation value displayed, the smaller the slope deviation between the lines (the closer the displayed value gets to 0, the closer all of the lines are to being exactly the same slope) and hence the smoother the price movement. And vice versa.
