This is a stunningly beautiful masterpiece in Pine, I must admit. That is some elegant array() work there! I do believe this is exemplary for the necessity for even more line.new(). It's definitely a top honors choice, if we had a yearly spotlight of the year's greatest achievements from adept "mathemagicians" via the "Power of Pine".

@midtownsk8rguy, I couldn't agree more with you on that note. Great job RicardoSantos! You just made everyone's day. I bet most mathematicians would be proud of this work. This should be implemented into TV's charting tools!!

This also triggers me thinking how to apply Polynomial regression for TA. Is that possible to make Polynomial regression "adaptive". I understand markets show volatile nature...

After testing this out this is 100 times more useful the stock linear regression. Holy this is game changing. Thank you again Ricardo, especially for keeping your scripts free for everyone to use. Truly a good man!

An excellent implementation example of array, thanks. Does array support newly introduced variable length?

Wow, this script shows how powerful PINE can be with the array function! Before I start the array application, let's learn these excellent cases first. This is what advanced PINE script programming can use: D
