(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!
