Thanks Vonasi, I hoped someone would give the indicator a look before adding to make sure the code is correct (it looks correct from the chart but I am not a coder)?
Here I’ve patched together the PRC R2 indicator with some of the code from John Ehler’s Correlation Trend indicator. Both codes are available, Ehler’s at the very top of this thread and PRC R2 via a url link. Does mine look correct and can you fix the period variable not having any impact on the red or blue line (you can only change the period via the code in the indicator)? Cheers.
