Cardwell RSI by TQ

4. Sept.

📌 Cardwell RSI – Enhanced Relative Strength Index
This indicator is based on Andrew Cardwell’s RSI methodology, extending the classic RSI with tools to better identify bullish/bearish ranges and trend dynamics.

In uptrends, RSI tends to hold between 40–80 (Cardwell bullish range).
In downtrends, RSI tends to stay between 20–60 (Cardwell bearish range).

Key Features:

• Standard RSI with configurable length & source
  
• Fast (9) & Slow (45) RSI Moving Averages (toggleable)
  
• Cardwell Core Levels (80 / 60 / 40 / 20) – enabled by default
  
• Base Bands (70 / 50 / 30) in dotted style
  
• Optional custom levels (up to 3)
  
• Alerts for MA crosses and level crosses
  
• Data Window metrics: RSI vs Fast/Slow MA differences
  

How to Use:

1. Monitor RSI behavior inside Cardwell’s bullish (40–80) and bearish (20–60) ranges
   
2. Watch RSI crossovers with Fast (9) and Slow (45) MAs to confirm momentum or trend shifts
   [\*] Use levels and alerts as confluence with your trading strategy
   

Default Settings:

• RSI Length: 14
  
• MA Type: WMA
  
• Fast MA: 9 (hidden by default)
  
• Slow MA: 45 (hidden by default)
  
• Cardwell Levels (80/60/40/20): ON

Changelog – Cardwell RSI → Cardwell RSI 1.2

1) Plot & Display

• RSI Line: remains, now in consistent color (#312e81), line width 2.
  
• Moving Averages: previously 2 (9/45); now 3 MAs:
  – Fast (9), Custom (user-defined, default 20), Slow (45).
  – All shown as lines (width 1).
  – Default ON (showMAs = true instead of false).
  
• Before: Fast MA was circles (style_circles).
  Now: All MAs are uniform line style for clarity.
  

2) Levels & Bands

• Core Levels: 80 / 60 / 40 / 20 remain – colors adjusted for visibility on light backgrounds.
  
• New Mid Levels 55/45: highlight transition/confirmation zones.
  
• Legacy Bands 70/50/30: still optional (dotted), now darker for better contrast.
  
• Before: Up to 3 user-defined Custom Levels (C1/C2/C3).
  Now: Removed → focus on Cardwell’s ranges & key mid-levels.
  

3) Regime Zones (new)

• Core Zone 60–40: highlighted with fill (light blue #38bdf8, ~20% visible).
  
• Throw Zones: above 60→63 and below 40→37 (dark green #065f46, ~20% visible).
  
• Purpose: Prevent misreading short spikes as regime shifts (Cardwell logic).
  

4) Colors & Readability

• Palette adapted for light background (#f5f0e1).
  
• Core levels = taupe shades, mid/legacy bands = darker taupe.
  
• MA colors unified: Fast = light blue, Custom = green, Slow = slate → quick visual separation.
  

5) Style Panel & Organization

• Cleaned-up titles: “Main RSI”, “MAs Fast/Custom/Slow”, “Level 80/60/…” etc.
  
• Helper plots for fills still technically required, but hidden (no titles) & placed at the bottom → less clutter in Style tab.
  

7) Data Window

• Deltas (RSI − Fast/Custom/Slow) still shown only in Data Window – not plotted.
  

Why these changes? (Purpose)

1. Cardwell Logic made visible: 60/40 shown as zones instead of just lines; throw-bands filter false regime shifts.
   
2. Better trend context: 55/45 mid-levels act as “rails” to assess transitions & confirmations.
   
3. Three MAs = structure: Fast (timing), Custom (flexible filter), Slow (regime).
   
4. MAs default ON: users immediately see rhythm/context.
   
5. Clearer visuals: Lines instead of circles, subtle fills, readable colors → less visual noise, fewer false reads.
   

Migration – What changes for users?

• Custom levels C1/C2/C3: removed → replace with built-in 55/45 mid-levels if needed.
  
• Fast MA circles: gone; all MAs are line-style for clarity.
  
• MAs visible by default: those who prefer a “naked RSI” can toggle off.
  
• New fills: Core Zone + Throw Zones are ON by default. Can be turned off via showThrow or showBase.
