[e2] Absolute Retracement

Absolute Retracement is a tool to obtain support and resistance levels.
It is designed for macro-level support and resistance and should be used on daily, weekly or monthly timeframes.


Instructions
1. Define the Reference Point

There are 4 methods to define reference point and start initialization of the script:
 - All Time Low / All Time High : The script is looking for the lowest low / highest high on entire history
 - Manual Low / Manual High : The user should define the reference point manually using the Previous Reference Point option

IMPORTANT NOTE: The correct reference point is:
 - the level at which prices have not exceeded during past 12-18 months
 - the All Time High / Low level

2. Level Calculation
There are 3 methods of level calculation for All Time Low and Manual Low modes (Fibonacci, Tribonacci,Tetranacci Sequence Calculator)

 - Fibonacci  sequence with the initialization numbers: {1, 1.61803 (Fibonacci Constant)}
 - Tribonacci sequence with the initialization numbers: {0, 1, 1.83929 (Tribonacci Constant)}
 - Tetranacci sequence with the initialization numbers: {0, 0, 1, 1.92756 (Tetranacci Constant)} 

The All Time High and Manual High modes use the Fibonacci Retracement logic and calculates 7 levels derived from the Fibonacci Constant (Golden ratio - 1.61803) (Fibonacci slicer)

3. Visualization
 - Different gradient modes (Color Gradient Function)
 - Option to show the Sequence Details (Sequence's name and number, factor)
 - Option to change the Sequence's level color (white, black, gradient) and turn off the label background
 - Move the reference point's label to the latest bar
