EMA Fib Strategy

### Description of the **EMA Fib Strategy** Script

This Pine Script defines an **Exponential Moving Average (EMA) Fibonacci Strategy**, a technical analysis tool that incorporates EMAs and Fibonacci retracement levels for trend and trade analysis. Here's a breakdown of its components and functionality:



### **Core Components**

#### **1. Inputs for EMA Calculations**
- **Short EMA (`emaShort`)**: A fast-moving average with a default period of 9, used for quick trend detection.
- **Long EMA (`emaLong`)**: A slower-moving average with a default period of 20, used for broader trend identification.
- **Trend EMA (`emaTrend`)**: A long-term moving average with a default period of 50, used to determine the overall market trend.

#### **2. EMA Calculations**
- The script calculates the Exponential Moving Averages for the closing prices:
- `emaShortValue`: Short EMA value.
- `emaLongValue`: Long EMA value.
- `emaTrendValue`: Trend EMA value.

### **Fibonacci Retracement Levels**
- **Fib 50% (`fib50`)**: Represents a 50% retracement level, often used to identify potential support/resistance zones.
- **Fib 70% (`fib70`)**: Represents a 70% retracement level, another key zone for possible price reversals.

> Note: These levels are inputs and currently not calculated dynamically based on price extremes. Manual adjustments may be require

### **Entry Conditions**
- **Bullish Crossover (`bullishCrossover`)**:
- Occurs when the `emaShortValue` crosses above the `emaLongValue`, signaling a potential upward trend.
- **Bearish Crossover (`bearishCrossover`)**:
- Occurs when the `emaShortValue` crosses below the `emaLongValue`, signaling a potential downward trend.


### **Visualization**
1. **Plotting EMAs:**
- `Short EMA`: Blue line.
- `Long EMA`: Red line.
- `Trend EMA`: Green line.
- These lines provide a visual representation of the market's short-term, medium-term, and long-term trends.

2. **Background Highlights:**
- **Green (Transparent)**: Indicates a bullish crossover, where the short EMA crosses above the long EMA.
- **Red (Transparent)**: Indicates a bearish crossover, where the short EMA crosses below the long EMA.


### **Strategy Logic (Optional)**
If used as a trading strategy, the script can generate trade signals:
- **Buy Signal**: Triggered when a bullish crossover occurs.
- **Close Signal**: Triggered when a bearish crossover occurs.

To enable strategy functionality, uncomment the following lines:
```pinescript
strategy.entry("Buy", strategy.long, when=bullishCrossover)
strategy.close("Buy", when=bearishCrossover)
```



### **Use Cases**
- **Traders and Analysts**: Use this script to identify trends, potential reversals, and support/resistance zones.
- **Backtesting Strategies**: Analyze how the EMA crossovers align with historical price action.
- **Trade Confirmation**: Combine with other indicators or patterns to confirm trades.

**Limitations**
- **Static Fibonacci Levels**: These levels are not dynamically calculated. Users must manually adjust them based on current price swings.
- **Lags in Moving Averages**: Like all EMA-based strategies, there may be a lag in detecting rapid market changes.
- **Additional Filters Needed**: For practical use, other filters or conditions (like volume or RSI) may enhance the strategy.
