## 🔧 HOW IT WORKS

### **Data Collection**
1. Fetches real-time spot/futures price
2. Calculates ATM (At-The-Money) strike automatically
3. Retrieves option prices for configured number of strikes
4. Pulls India VIX for volatility estimation

### **Greeks Calculation**
- Implements Black-Scholes model for European options
- Calculates Delta, Gamma, Theta, Vega, Rho for each strike
- Uses 3 days to expiry (configurable via expiry date input)
- Adjusts for Indian market conventions

### **Max Pain Calculation**
- Simulates price settlement at each strike
- Calculates total option buyer losses (Calls + Puts)
- Identifies strike with maximum buyer loss
- Updates in real-time as prices change

### **PCR Analysis**
- Computes Put/Call premium ratio at each strike
- Aggregates overall PCR across all strikes
- Color-codes based on sentiment thresholds
- Identifies support/resistance from extreme PCR values

### **Signal Generation**
Combines multiple factors:
- Greek values (especially Delta, Gamma, Theta)
- VIX level (volatility environment)
- PCR sentiment (fear/greed gauge)
- Max Pain distance (price magnet)
- Generates BUY or SELL recommendations with specific strikes

## ⚠️ IMPORTANT NOTES

### **Data Limitations**
- Uses **simplified Greeks** calculation (assumes 3 DTE by default)
- Option prices may have slight delays (TradingView data refresh)
- Max Pain calculation is **approximation** based on current premiums
- Not all option symbols may be available on TradingView

### **Best Practices**
1. **Verify prices** on your broker platform before trading
2. **Use during market hours** (9:15 AM - 3:30 PM IST) for accurate data
3. **Most effective** 3-5 days before expiry
4. **Combine with price action** and trend analysis
5. **Risk management**: Never risk more than 2% per trade

### **Optimization Tips**
- **Increase strikes** to 9-11 for better Max Pain accuracy
- **Use FUTURES** tracking for liquid indices (NIFTY, BANKNIFTY)
- **Enable debug mode** initially to verify symbols are correct
- **Adjust IV Multiplier** if VIX seems over/underestimated

## 📖 EDUCATIONAL RESOURCES

### **Understanding Greeks**
- **Delta**: Rate of change in option price vs underlying (0-1 for calls, -1-0 for puts)
- **Gamma**: Rate of change of Delta (highest at ATM)
- **Theta**: Time decay per day (always negative for buyers)
- **Vega**: Sensitivity to volatility changes
- **Rho**: Sensitivity to interest rate changes (less important for short-term)

### **Max Pain Theory**
Max Pain suggests that market makers manipulate prices toward the strike where option buyers lose the most money. While controversial, it has statistical validity in expiry week when:
1. Volume is high
2. Market makers hedge positions
3. Pin risk causes clustering at certain strikes

### **PCR as Sentiment Indicator**
- PCR > 1: More put buying than call buying (bearish)
- PCR < 1: More call buying than put buying (bullish)
- **Contrarian use**: Extreme readings often precede reversals
- **Confirmation use**: With trend for continuation trades
