+# Technical Analysis
+
+## Overview
+
+The technical analysis module processes raw market data through multiple analytical lenses to identify high-probability trading setups within the 30-minute hold constraint.
+
+## Analysis Categories
+
+### 1. Trend Indicators
+
+| Indicator | Parameters | Signal |
+|---|---|---|
+| EMA Cross | 9/21 periods | Bullish/Bearish cross |
+| MACD | 12/26/9 | Histogram divergence |
+| ADX | 14 periods | Trend strength > 25 |
+| Parabolic SAR | 0.02/0.2 | Trend reversal dots |
+
+### 2. Momentum Indicators
+
+| Indicator | Parameters | Signal |
+|---|---|---|
+| RSI | 14 periods | Oversold < 30, Overbought > 70 |
+| Stochastic | 14/3/3 | %K/%D crossover |
+| CCI | 20 periods | Extreme readings ±200 |
+| Williams %R | 14 periods | Reversal zones |
+
+### 3. Volatility Indicators
+
+| Indicator | Parameters | Signal |
+|---|---|---|
+| Bollinger Bands | 20/2σ | Band squeeze/expansion |
+| ATR | 14 periods | Position sizing, stop distance |
+| Keltner Channels | 20/1.5 | Breakout confirmation |
+
+### 4. Volume Analysis
+
+| Indicator | Parameters | Signal |
+|---|---|---|
+| VWAP | Session | Price vs fair value |
+| OBV | Cumulative | Divergence from price |
+| Volume Profile | Session | Key levels, POC |
+
+## Pattern Recognition
+
+### Candlestick Patterns (1-5 bar)
+- **Reversal**: Hammer, Shooting Star, Engulfing, Morning/Evening Star
+- **Continuation**: Three White Soldiers, Rising/Falling Three Methods
+- **Indecision**: Doji, Spinning Top, Harami
+
+### Chart Patterns (Multi-bar)
+- Double Top/Bottom
+- Head & Shoulders
+- Ascending/Descending Triangles
+- Bull/Bear Flags
+- Wedges
+
+## Confluence Scoring
+
+Signals are scored based on **confluence** — multiple indicators agreeing:
+
+```python
+def calculate_confluence_score(signals: list[IndicatorSignal]) -> float:
+    """
+    Score 0.0 - 1.0 based on how many indicators agree.
+    
+    Weights:
+    - Trend alignment: 0.30
+    - Momentum confirmation: 0.25
+    - Volume confirmation: 0.20
+    - Pattern match: 0.15
+    - Key level proximity: 0.10
+    """
+    weights = {
+        'trend': 0.30,
+        'momentum': 0.25,
+        'volume': 0.20,
+        'pattern': 0.15,
+        'level': 0.10
+    }
+    
+    score = sum(
+        weights[s.category] * s.strength 
+        for s in signals 
+        if s.direction == consensus_direction(signals)
+    )
+    return min(score, 1.0)
+```
+
+**Minimum confluence threshold for signal generation: 0.65**
+
+## Timeframe Analysis
+
+Given the 30-minute max hold constraint:
+
+| Timeframe | Purpose |
+|---|---|
+| 1-minute | Entry timing, micro-structure |
+| 5-minute | Primary signal generation |
+| 15-minute | Trend context, S/R levels |
+| 1-hour | Bias direction (trend filter) |
+
+## Backtesting Requirements
+
+- Minimum 30 days historical data
+- Walk-forward optimization
+- Out-of-sample validation
+- Maximum drawdown tracking
+- Sharpe ratio > 1.5 target
