Ratio Calculations
Body to Range Ratio
Example 1: Strong Body (Marubozu)
High (2050)
┌─┴─┐
│ │
│ │ Body = 48
│ │ Range = 50
│ │ Ratio = 0.96 (96%)
│ │
└─┬─┘
Low (2000)
Example 2: Small Body (Doji)
High (2050)
│
│
─┼─ Body = 2
│ Range = 50
│ Ratio = 0.04 (4%)
│
Low (2000)
Example 3: Medium Body (Standard)
High (2050)
│
┌─┴─┐
│ │ Body = 25
│ │ Range = 50
└─┬─┘ Ratio = 0.50 (50%)
│
Low (2000)
Wick Ratios
Example: Hammer Pattern
High (2050)
│
┌─┴─┐
│ │ Body = 10 (20% of range)
└─┬─┘ Upper wick = 5 (10% of range)
│
│
│ Lower wick = 35 (70% of range)
│
│
Low (2000)
Interpretation:
- Small body at top
- Long lower wick (rejection of lower prices)
- Bullish reversal signal

Decision Tree Example
Is current candle unusually large?
│
├─ YES (relative_size > 2.0)
│ │
│ ├─ Is it bullish?
│ │ │
│ │ ├─ YES → Strong bullish momentum
│ │ │ Action: Consider long entry
│ │ │
│ │ └─ NO → Strong bearish momentum
│ │ Action: Consider short entry
│ │
│ └─ Is body > 80% of range?
│ │
│ ├─ YES → Marubozu (strong conviction)
│ │ Action: High confidence trade
│ │
│ └─ NO → Large wicks (rejection)
│ Action: Wait for confirmation
│
└─ NO (relative_size ≤ 2.0)
│
├─ Is it a hammer or shooting star?
│ │
│ ├─ YES → Potential reversal
│ │ Action: Watch for confirmation
│ │
│ └─ NO → Continue
│
└─ Is it a doji?
│
├─ YES → Indecision
│ Action: Wait for direction
│
└─ NO → Standard candle
Action: Follow trend
