Rolling VWAP Oscillator

TL;DR - TradingView's Rolling VWAP as centered oscillator

I really like TradingView's rolling VWAP (Rolling Volume-Weighted Average Price - RVWAP) indicator. But I also like clean charts that's why I'm mainly using indicators which are not displayed on the chart. Instead of simply moving the RVWAP to another pane I turned it into a centered oscillator. This allows me checking the RVWAP while having my chart clean.

You can find the oroginal RVWAP here.

Creds to TradingView for creating this indicator 👍

* I also added a fourth deviation band, gradient colors and the option to switch between candles and lines.
