# Auto Fib V1.3
# tomsk
# 11.19.2019
# Automatically draws fibonacci retracements using the highest price and lowest price
# from the current view and timeframe.
#
# Fibonacci retracements use horizontal lines to indicate areas of support or resistance
# at the key Fibonacci levels before it continues in the original direction. These levels
# are created by drawing a trendline between two extreme points and then dividing the
# vertical distance by the key Fibonacci ratios of: 23.6%, 38.2%, 50%, 61.8%, 78.6%, and 100%.
# CHANGE LOG
#
# V1.0 - 12.18.2018 - BenTen - Initial release of Auto Fib, created by Ryan Hendricks
# V1.1 - 11.15.2019 - theelderwand - As script was difficult to read, made the following enhancements
# Expands to right
# Doesn't expand to left
# Custom colors for Fibonacci bars (0.618 is GOLD color)
# Custom line weights
# Code is modularized so you can add extra plots as needed
# V1.2 - 11.15.2019 - tomsk - Added an input selector for the colors of the label. You
# can select from any of the colors listed - red, orange,
# green, etc and bubbles for all the fib retracements will
# utilize that color.
# V1.3 - 11.19.2019 - tomsk - Modified the AddChartBubbles to be displayed on the right
# side of the chart. Please ensure that you increase the
# expansion area to that the bubbles have room to be displayed
