The skill will automatically activate when you use phrases like:
#### Primary Activation Phrases
1. **"analyze stock"**
- Example: "Analyze AAPL stock performance"
2. **"technical analysis for"**
- Example: "Show me technical analysis for MSFT"
3. **"RSI indicator"**
- Example: "What's the RSI indicator for TSLA?"
#### Workflow-Based Activation
4. **"buy signal for"**
- Example: "Is there a buy signal for NVDA?"
5. **"compare stocks using"**
- Example: "Compare AAPL vs GOOGL using RSI"
#### Domain-Specific Activation
6. **"MACD indicator"**
- Example: "Show MACD indicator for AMD"
7. **"Bollinger Bands"**
- Example: "Calculate Bollinger Bands for SPY"
#### Natural Language Variations
8. **"What's the technical setup for [TICKER]"**

9. **"Monitor stock price"**
- Example: "Monitor AMZN stock price and alert on RSI oversold"
10. **"Chart pattern analysis"**
- Example: "Analyze chart patterns for NFLX"
### ❌ Phrases That Do NOT Activate
To prevent false positives, this skill will **NOT** activate for:
1. **Fundamental Analysis Requests**
- Example: "What's the P/E ratio of AAPL?"
- Reason: This skill focuses on technical analysis, not fundamentals
2. **News or Sentiment Analysis**
- Example: "What's the latest news about TSLA?"
- Reason: This skill analyzes price/volume data, not news sentiment
3. **General Market Education**
- Example: "How do stocks work?"
- Reason: This is educational content, not technical analysis
### 💡 Activation Tips
To ensure reliable activation:
**DO:**
- ✅ Use action verbs: analyze, compare, monitor, track, show
- ✅ Be specific about: stock ticker symbols (AAPL, MSFT, etc.)
- ✅ Mention: technical indicators (RSI, MACD, Bollinger Bands)
- ✅ Include context: "for trading", "technical analysis", "buy signals"
**DON'T:**
- ❌ Use vague phrases like "tell me about stocks"
- ❌ Omit key entities like ticker symbols or indicator names
- ❌ Be too generic: "analyze the market"
### 🎯 Example Activation Patterns
**Pattern 1:** Technical Indicator Analysis
```
User: "Show me RSI and MACD for AAPL"
Result: ✅ Skill activates via Keyword Layer (RSI indicator, MACD indicator)
```
**Pattern 2:** Signal Generation
```
User: "Is there a buy signal for NVDA based on technical indicators?"
Result: ✅ Skill activates via Pattern Layer (buy signal + technical)
```
**Pattern 3:** Stock Comparison
```
User: "Compare these tech stocks using momentum indicators"
Result: ✅ Skill activates via Pattern Layer (compare.*stocks)
```

## Usage
### Basic Usage
```python
# Analyze a single stock
from stock_analyzer import StockAnalyzer
analyzer = StockAnalyzer()
result = analyzer.analyze("AAPL", indicators=["RSI", "MACD"])
print(result)
```
### Advanced Usage
```python
# Compare multiple stocks with custom parameters
analyzer = StockAnalyzer()
comparison = analyzer.compare(
tickers=["AAPL", "MSFT", "GOOGL"],
indicators=["RSI", "MACD", "Bollinger"],
period="1y"
)
print(comparison.ranked_by_momentum())
```

## Troubleshooting
### Issue: Skill Not Activating
**Symptoms:** Your query doesn't activate the skill
**Solutions:**
1. ✅ Use one of the activation phrases listed above
2. ✅ Include action verbs: analyze, compare, monitor, track
3. ✅ Mention specific entities: ticker symbols, indicator names
4. ✅ Provide context: "technical analysis", "using RSI"
**Example Fix:**
```
❌ "What about AAPL?"
✅ "Analyze AAPL stock using technical indicators"
```
### Issue: Wrong Skill Activates
**Symptoms:** A different skill activates instead
**Solutions:**
1. Be more specific about technical analysis
2. Use technical indicator keywords: RSI, MACD, Bollinger Bands
3. Add context that distinguishes from fundamental analysis
**Example Fix:**
```
❌ "Analyze AAPL" (too generic, might trigger fundamental analysis)
✅ "Technical analysis of AAPL using RSI and MACD" (specific to this skill)
```

### Main Orchestrator (main.py)
```python
"""
Stock Analyzer - Technical Analysis Skill

### Indicator Calculators
Each indicator has dedicated calculator following Single Responsibility Principle:
- **RSICalculator**: Computes Relative Strength Index
- **MACDCalculator**: Computes Moving Average Convergence Divergence
- **BollingerCalculator**: Computes Bollinger Bands (upper, middle, lower)
### Signal Generator
Interprets indicator combinations to produce buy/sell/hold recommendations:
```python
class SignalGenerator:
"""Generates trading signals from technical indicators"""
def generate(self, ticker: str, data: pd.DataFrame, indicators: Dict):
"""
Generate trading signal from indicator combination
Strategy: Combined RSI + MACD approach
- BUY: RSI < 50 and MACD bullish crossover
- SELL: RSI > 70 and MACD bearish crossover
- HOLD: Otherwise
"""
rsi = indicators.get('RSI', {}).get('value')
macd = indicators.get('MACD', {})
signal = "HOLD"
confidence = "low"
reasoning = []
# RSI analysis
if rsi and rsi < 30:
reasoning.append("RSI oversold (< 30)")
signal = "BUY"
confidence = "moderate"
elif rsi and rsi > 70:
reasoning.append("RSI overbought (> 70)")
signal = "SELL"
confidence = "moderate"
# MACD analysis
if macd.get('signal') == 'bullish_crossover':
reasoning.append("MACD bullish crossover")

return {

## Usage Examples
### when_to_use Cases (from marketplace.json)
1. ✅ "Analyze AAPL stock using RSI indicator"
2. ✅ "What's the MACD for MSFT right now?"
3. ✅ "Show me buy signals for tech stocks"
4. ✅ "Compare AAPL vs GOOGL using technical analysis"
5. ✅ "Monitor TSLA and alert when RSI is oversold"
### when_not_to_use Cases (from marketplace.json)
1. ❌ "What's the P/E ratio of AAPL?" → Use fundamental analysis skill
2. ❌ "Latest news about TSLA" → Use news/sentiment skill
3. ❌ "How do I buy stocks?" → General education, not analysis
4. ❌ "Execute a trade on NVDA" → Brokerage operations, not analysis
5. ❌ "Analyze options strategies" → Options analysis (different skill)
