//This script creates a Decimal and Binary representation of the price using ROC. The idea is to simplify the price action into a distance from Zero to upside and downside.
//You can see clearly rend develops in the ROC in the decimal view, kind of like AMCD but based on raw price action change. I'm' a big fan of raw price action, so my scripts are super simple.
//You can also use this script in a binary mode close higher = 1 and lower is -1. I use the binary mode to remove the phycological pressure of watching the stock going against me. I turn off the actual price and only focus on
// Simple up and down movements are counting the number of red and Blue. On a Quntum physics level, when I short, I wish for more reds.
//
// 2021-10-10 - GD Updated candle colours to red green and removed black candle borders so improves visibility when compressing candles, no longer turns black.
// 2021-10-10 - GD Updated to Version 5 Pine Script
