3D Cube Projection - √3 Diagonal3D Cube Projection - √3 Diagonal
OVERVIEW
This indicator implements Bradley F. Cowan's cube projection methodology from his "Four Dimensional Stock Market Structures & Cycles" work. It visualizes a 3D cube projected onto the 2D price-time chart, using the √3 (square root of 3) body diagonal as the primary analytical tool for identifying market structure and potential cycle termination points.
METHODOLOGY
The cube is constructed by selecting two pivot points (A and E) which form the body diagonal - the longest diagonal running through the cube's interior from one corner to the diagonally opposite corner. According to Cowan's geometric approach:
- Point A = Starting pivot (low or high)
- Point E = Ending pivot (opposite extreme)
- Body Diagonal (A→E) = √3 × cube side length
- Face Diagonal (A→C) = √2 × cube side length
The script calculates the cube dimensions by:
1. Measuring the total price range from A to E
2. Dividing by √3 to determine the cube side length in price
3. Distributing the time component across three equal segments
4. Projecting the 3D structure onto the 2D chart plane
FEATURES
✓ Interactive date selection for points A and E
✓ Automatic UPLEG/DOWNLEG detection
✓ All 8 cube vertices labeled (A-H)
✓ All 6 cube faces with independent color/opacity controls
✓ √3 body diagonal (red line by default)
✓ √2 face diagonal (orange line by default)
✓ Customizable cube lines, fills, and labels
✓ Information table showing key measurements
VISUAL CUSTOMIZATION
- Front & Back faces: Box fills for the two square faces
- Side faces: Left and right vertical faces
- Top & Bottom faces: Horizontal connecting faces
- Each group has independent color and opacity settings
- Label size and transparency fully adjustable
- Cube line styles (solid, dashed, dotted) for depth perception
IMPORTANT LIMITATIONS & DISCLOSURES
This indicator works within the inherent constraints of projecting 3D geometry onto a 2D price-time chart:
⚠️ VISUAL APPROXIMATION: This is a visual projection tool, not a mathematically perfect 3D cube. True 3D geometry cannot be accurately represented on a 2D plane without distortion.
⚠️ TIME DISTRIBUTION: The script divides the time axis into three equal segments (total bars ÷ 3) for practical visualization. This is an approximation that prioritizes visual coherence over strict geometric accuracy.
⚠️ UNIT SCALING: Price and time use different units (dollars vs. bars), making true isometric projection impossible. The cube appears proportional on screen but the dimensions are not directly comparable.
⚠️ 2D CONSTRAINT: We only have X (time) and Y (price) axes available. The Z-axis (depth) is simulated through visual projection techniques (line styles, shading).
INTENDED USE
This tool is designed for traders and analysts who study Bradley Cowan's geometric market analysis methods. It helps visualize:
- Market structure in geometric terms
- Potential support/resistance zones at cube edges
- Cycle timing relationships using √2 and √3 ratios
- Harmonic price-time relationships
The cube projection should be used as one component of a comprehensive analysis approach, combined with other technical tools and fundamental analysis.
MATHEMATICAL FOUNDATION
While the visual representation involves approximations, the core √3 relationship is mathematically sound:
- For any cube, the body diagonal = √3 × side length
- The face diagonal = √2 × side length
- These ratios are preserved in the price dimension calculations
HOW TO USE
1. Select your starting date (Point A) - typically a significant low or high
2. Select your ending date (Point E) - the opposite extreme pivot
3. The indicator automatically constructs the cube geometry
4. Analyze the cube edges, diagonals, and faces for market structure insights
5. Adjust colors and opacity to suit your chart aesthetic
TECHNICAL NOTES
- Works on all timeframes and instruments
- Best viewed on charts with sufficient historical data
- Cube updates in real-time as new bars form
- Range selection is marked with vertical lines and shading
- Calculator table shows Point A, Point E, side length, and bar measurements

Geometric Price-Time Triangle Calculator═══════════════════════════════════════════════════
GEOMETRIC PRICE-TIME TRIANGLE CALCULATOR
═══════════════════════════════════════════════════
Calculates Point C of a geometric triangle using different rotation angles from any selected price swing. Based on Bradley F. Cowan's Price-Time Vector (PTV) methods from "Four-Dimensional Stock Market Structures and Cycles."
📐 WHAT IT DOES
────────────────────────────────────────────────────
Select two points (A and B) on any swing, choose an angle, and the indicator calculates where Point C would be mathematically. It's just vector rotation applied to price charts.
This shows you where Point C lands in both price AND time based on pure geometry - not a prediction, just a calculation.
🎯 FEATURES
────────────────────────────────────────────────────
✓ 10 Different Angles
• Gann ratios: 18.435° (1x3), 26.565° (1x2), 45° (1x1), 63.435° (2x1), 71.565° (3x1)
• Other angles: 30°, 60°, 90°, 120°, 150°
✓ Visual Triangle
• Adjustable colors and opacity for points A, B, C
• Line styles: Solid, Dashed, Dotted
• Extend lines: None, Left, Right, Both
✓ Crosshair at Point C
• Shows where Point C is located
• Vertical line = bar position
• Horizontal line = price level
✓ Data Table
• Shows all calculations
• Price-to-Bar ratio
• Point C location (price and bars from A/B)
• Toggle on/off
🔧 HOW TO USE
────────────────────────────────────────────────────
1. Pick your swing start date (Point A)
2. Pick your swing end date (Point B) - make sure these dates capture the actual high/low of your swing
3. Choose an angle from the dropdown
4. Look at Point C - that's where the geometry puts it
Different angles = different Point C locations. Whether price actually goes there is up to the market.
📊 THE ANGLES
────────────────────────────────────────────────────
- 18.435° (1x3) - Shallow rotation
- 26.565° (1x2) - Moderate rotation
- 45° (1x1) - Gann's balanced ratio
- 60° - Equilateral triangle (default)
- 63.435° (2x1) - Steeper rotation
- 71.565° (3x1) - Very steep rotation
- 90° - Right angle
- 120°-150° - Obtuse angles
💡 PRACTICAL USE
────────────────────────────────────────────────────
→ See where geometric patterns would complete
→ Test if your market respects certain angles
→ Find where multiple angles converge
→ Compare projected Point C to actual price action
→ Use 90° to see symmetrical price/time relationships
→ Backtest historical swings to see what worked
⚙️ HOW IT WORKS
────────────────────────────────────────────────────
1. Takes your AB swing
2. Calculates the BA vector (reverse direction)
3. Normalizes price and time using Price-to-Bar ratio
4. Rotates the vector by your selected angle
5. Converts back to chart coordinates
Basic trigonometry. That's all it is.
📚 BACKGROUND
────────────────────────────────────────────────────
Based on Bradley F. Cowan's Price-Time Vector (PTV) concept from "Four-Dimensional Stock Market Structures and Cycles" and W.D. Gann's geometric angle analysis. Cowan observed that markets sometimes complete geometric patterns. This tool calculates where those patterns would complete mathematically. Whether price actually respects these geometric relationships is something you need to test yourself.
⚠️ IMPORTANT
────────────────────────────────────────────────────
- This is geometric calculation, not prediction
- Point C shows where the math puts it, not where price will go
- Some angles might work for your market, some won't
- Test it yourself on historical data
- Price-to-Bar Ratio stays constant regardless of angle
- Don't trade based on this alone
- Works on all timeframes and assets
🎨 CUSTOMIZATION

- Individual colors for A, B, C points
- Adjust opacity (0-100)
- Line styles for each triangle side
- Extend lines left/right/both/none
