Indicator Levels

The indicator displays reference levels at:

• 0% - Equilibrium (white solid line)
• ±5% - Moderate zones (gray dotted)
• ±10% - Moderate zones (gray dotted)
• ±15% - Strong zones (gray dotted)
• ±20% - Extreme zones (gray dotted)

Calculation Methods

HP Filter Algorithm

The indicator uses two calculation methods:

1. Thomas Algorithm (Primary)

   • Fast tridiagonal matrix solver
   • Efficient for real-time calculation
   • O(n) computational complexity

2. Iterative Method (Fallback)

   • Used if Thomas Algorithm fails
   • Maximum 100 iterations
   • Convergence tolerance: 1e-6

Bubble Percentage Formula

Bubble% = ((Current Price - Trend) / Trend) × 100

Signal Line Methods

Supports 4 moving average types:

• SMA - Simple Moving Average
• EMA - Exponential Moving Average (default)
• SMMA - Smoothed Moving Average
• LWMA - Linear Weighted Moving Average

Usage Guidelines

Interpreting Signals

Overbought Conditions:

• Strong Overbought (>15%): Consider taking profits or waiting for pullback
• Moderate Overbought (5-15%): Trend strength, watch for reversal signs

Equilibrium Zone (-5% to +5%):

• Price close to fair value
• Potential consolidation or trend transition

Oversold Conditions:

• Moderate Oversold (-15 to -5%): Potential buying opportunity
• Strong Oversold (<-15%): Strong reversal candidate, but confirm trend

Multi-Timeframe Confirmation

• Bullish Setup: Both current and higher TF showing positive bubbles
• Bearish Setup: Both timeframes showing negative bubbles
• Divergence: Different signals between timeframes suggest caution
