Auto Fibonacci Retracements with Alerts [SwissAlgo]

AUTO-FIBONACCI RETRACEMENT: LEVELS, ALERTS & PD ZONES
Automatically maps Fibonacci retracement levels with Premium/Discount (PD) zones and configurable alerts for technical analysis study.
------------------------------------------------------------------
FEATURES
Automatic Fibonacci Levels Detection

• Identifies swing extremes (reference high and low to map retracements) from a user-defined trend start date and trend indication automatically
  
• Calculates 20 Fibonacci levels (from -2.618 to +2.618) automatically
  
• Dynamically updates Fib levels as price action develops, anchoring the bottom (in case of uptrends) or the top (in case of downtrends)
  
• Detects potential Trend's Change of Character automatically
  
• Premium/Discount (PD) zone visualization based on trend and price extremes
  

Visual Components

• Dotted horizontal lines for each Fibonacci level
  
• 'Premium' and 'discount' zone highlighting
  
• Change of Character (CHoCH) marker when a trend anchor breaks (a bottom is broken after an uptrend, a top is broken after a downtrend)
  
• Adaptive label colors for light/dark chart themes
  

Alert System

• Configurable alerts for all Fibonacci levels
  
• Requires 2 consecutive bar closes for confirmation (reduces false signals)
  
• CHoCH alert when a locked extreme is broken
  
• Set up using "Any alert() function call" option

USE CASES

Two Primary Use Cases:

1. PROSPECTIVE TREND MAPPING (Real-Time Tracking)
Set start date at or just before an anticipated swing extreme to track levels as the trend develops:

• For Uptrend: Place start date near a bottom. The bottom level locks after consolidation, while the top updates in real-time as the price climbs higher
  
• For Downtrend: Place start date near a top. The top-level locks after consolidation, while the bottom updates in real-time as the price falls lower
  

This mode tracks developing price action against Fibonacci levels as the swing unfolds.

2. RETROSPECTIVE ANALYSIS (Historical Swing Study)
Set the start date at a completed swing extreme to analyze how the price interacted (and is interacting) with the Fibonacci levels:

• Both high and low are already established in the historical data
  
• Levels remain static for analysis purposes
  
• Useful for analyzing price behavior relative to Fibonacci levels, studying retracement dynamics, and assessing a trading posture
  

------------------------------------------------------------------
HOW TO USE

• Set 'Start Date': Select Start Date (anchor point) at or just before the swing extreme (bottom for uptrend, top for downtrend)
  
• Choose Trend Direction (Up or Down): direction is known for retrospective analysis, uncertain for prospective analysis
  
• Update the start date when significant structure breaks occur to begin analyzing a new swing cycle.
  
• Configure alerts as needed for your analysis

TECHNICAL DETAILS

♦ Auto-Mapped Fibonacci Retracement Levels:
2.618, 2.000, 1.618, 1.414, 1.272, 1.000, 0.882, 0.786, 0.618, 0.500, 0.382, 0.236, 0.118, 0.000, -0.272, -0.618, -1.000, -1.618, -2.000, -2.618
♦ Premium/Discount (PD) Zones:

• Uptrend: Green (discount zone) = levels 0 to 0.5 | Red (premium zone) = levels 0.5 to 1.0
  
• Downtrend: Red (premium zone) = levels 0 to 0.5 | Green (discount zone) = levels 0.5 to 1.0
  
• The yellow line represents the 0.5 equilibrium level
  

♦ Lock Mechanism:
The indicator monitors for new extremes to detect a Change of Character in the trend (providing visual feedback and alerts). It locks the anchor swing extreme after a timeframe-appropriate consolidation period has elapsed (varies from 200 bars on second charts to 1 bar on monthly charts) to detect such potentially critical events.
