Correlation [array's]

This script isn't about creating a correlation script with labels, there is a perfect working example of Mango2Juice
(Correlation Matrix, which was inspired by Daveatt's Correlation Matrix)

The intention was making it with the use of as less code as possible, looping through array's

The Pine correlation function doesn't work consistently in a local scope (loop), so I had to work around it

Inspired by ZenAndTheArtOfTrading's Correlation Meter (using array.covariance and array.stdev) and
especially with the help of RicardoSantos and LonesomeTheBlue I've managed to do this

Symbols, timeframe, look-back period, colors and limits can be changed

There is always room for improvement, but I think it shows what is possible.

Many thanks to the people who I've mentioned, and of course to Tradingview!
