Nearest Percentile Moving Average Bands

While coding some filters into another indicator for Long/Short I noticed that ta.nearest.percentile might be the most useful tool in pinescript I've ever encountered.
While percentile_nearest can be used for all kind of things I decided to code moving averages from it and made bands for bottom percentage and top percentage.

The indicator will calculate the top % price of the given bar length.
Example settings:
length: 150
percentile: 99
So when using 99% it will draw a green line when price is moving above the top 1% price of the last 150 candles. It then calculates if the price is below the bottom 1% of the last 150 candles.

Trading use:
Use this indicator to check if the market is leaving normal territory. This signals a breakout move for example the dogecoin pump or the top of the range. I use this indicator to catch bull/bear moves for botting purposes. An other use would be to countertrend trade after the move has ended. With price being in top 1% for a while it is very probable that we see a large correction.
