Candle Range Extension

This script defines an indicator called "Candle Range Extension" that calculates the range of each candle (high minus low) and then multiplies that range by 3 to get the extension distance. It then plots two lines on the chart: one line that extends 3 times the candle range above the candle's high (in green) and another line that extends 3 times the candle range below the candle's low (in red).
