The Ultimate Indicator: Bollinger Bands
Bollibang!! master b includes Bollinger Band %b. It is an indicator for evaluating "band walks". ─────────────────────────────────────────────────────
Overview
─────────────────────────────────────────────────────
─────────────────────────────────────────────────────
Sub-window 1 — Bollinger BandWidth (BBW)
─────────────────────────────────────────────────────
[cite_start]Displays the magnitude of volatility relative to the middle band as a percentage[cite: 1].
[cite_start]• BandWidth Line — Current volatility level [cite: 1]
[cite_start]• BBW MA Line — Smoothed BBW line to identify trends [cite: 1]
[cite_start]• Highest Expansion — Maximum BBW over the past N bars (reference for expansion) [cite: 1]
[cite_start]• Lowest Contraction — Minimum BBW over the past N bars (reference for contraction) [cite: 1]
─────────────────────────────────────────────────────
Sub-window 2 — Bollinger %b
─────────────────────────────────────────────────────
[cite_start]Visualizes the position of the price within the bands on a 0 to 1 scale[cite: 1].
[cite_start]0.0 = Lower Band / 0.5 = Middle Band / 1.0 = Upper Band[cite: 1].
[cite_start]• %b Line — Current price position within the bands [cite: 1]
[cite_start]• %b MA Line — Smoothed %b line to grasp momentum [cite: 2]
[cite_start]• Overbought Level 1.0 — Price reached the upper band (Red) [cite: 2]
[cite_start]• Neutral Level 0.5 — Price near SMA / Equilibrium Zone (Blue) [cite: 2]
[cite_start]• Oversold Level 0.0 — Price reached the lower band (Green) [cite: 2]

Key Insights at a Glance
─────────────────────────────────────────────────────
Detecting Squeezes
BBW drops to the Lowest Contraction line → Volatility is contracting. [cite_start]The market is preparing for a breakout[cite: 2].
Confirming Breakouts
[cite_start]BBW expands towards the Highest Expansion line while %b exceeds 1.0 or falls below 0.0 → This indicates a real move accompanied by momentum[cite: 2].
Contrarian Signals
BBW remains low while %b reaches an extreme value → Indicates price extension without momentum. [cite_start]Suggests a good opportunity for a contrarian trade[cite: 2].
Trend Strength
[cite_start]%b MA remains above 0.5 while BBW expands → A healthy and sustainable trend is in progress[cite: 2].

Parameters
─────────────────────────────────────────────────────
[cite_start]BB Period 20 Calculation period (common for BBW and %b) [cite: 3]
[cite_start]Source Close Price source used for calculation [cite: 3]
[cite_start]BBW StdDev Multiplier 2.0 Standard deviation multiplier for BBW [cite: 3]
[cite_start]MA Period 5 Period for BBW MA and %b MA (common) [cite: 3]
[cite_start]Highest Expansion Length 125 Number of bars to reference for maximum BBW [cite: 4]
[cite_start]Lowest Contraction Length 125 Number of bars to reference for minimum BBW [cite: 4]
[cite_start]%b StdDev Multiplier 1.0 Standard deviation multiplier for %b bands [cite: 4]

Conditions for Band Walk
[cite_start]• BBW moves near the Lowest Contraction line (band width contracts to form a tunnel)[cite: 4].
[cite_start]• The 5MA of %b breaks out of the upper band (1.0) or lower band (0.0) (5MA breaks out of 1σ)[cite: 4].
[cite_start]• The BBW line forms a golden cross with the 5MA, signaling increasing momentum[cite: 4].
-------- Tips to Increase Win Rate: Using ADX ----------
[cite_start]ADX line order (Top to Bottom): ADX, +DI, -DI → Uptrend[cite: 4].
[cite_start]ADX line order (Top to Bottom): ADX, -DI, +DI → Downtrend[cite: 4].
