Built-in RSI indicator has an error in the algorithm.
I spotted the error while working on a modified RSI where i needed the original algorithm with special input
I started with the official formula and were having different curves from the built-in indicator.
after thinking I had made a mistake in the algorithm, I realized the orginal indicator is wrong by looking at the code.
So here is the real RSI, computed from the original formula, so you know it's the real indicator.
