ieriThis Pine Script code combines multiple technical indicators into one overlay on a TradingView chart. The indicators included are:

### 1. **Exponential Moving Averages (EMAs):**
- **9 EMA**: Blue line, calculated using a 9-period exponential moving average of the closing prices.
- **21 EMA**: Red line, calculated using a 21-period exponential moving average.
- **50 EMA**: Green line, calculated using a 50-period exponential moving average.

These EMAs help identify trends by smoothing out price movements over different periods.

### 2. **Bollinger Bands:**
- The middle line is an **SMA (Simple Moving Average)** with a period of 20 (orange line).
- The upper and lower bands (gray lines) represent 2 standard deviations from the SMA, forming the Bollinger Bands. These bands measure volatility, widening when volatility increases and narrowing when volatility decreases.
- The area between the upper and lower bands is filled with a semi-transparent gray color for better visualization.

### 3. **VWAP (Volume Weighted Average Price):**
VWAP is calculated using the **HLC3** (average of high, low, and close prices) as the data source. It represents the average price weighted by volume over a specified period:
- **Daily VWAP**: Purple line.
- **Weekly VWAP**: Pink line.
- **Monthly VWAP**: Teal line.
- **Yearly VWAP**: Yellow line.

These VWAPs are plotted on the chart to show average price movement over different timeframes.

### 4. **ADX (Average Directional Index):**
- The ADX is plotted as a fuchsia line to measure the strength of a trend. Higher values indicate a stronger trend, while lower values indicate a weaker trend.
- Two horizontal lines at **25** (green) and **50** (red) help visualize ADX thresholds. A value above 25 indicates a strong trend, and above 50 indicates a very strong trend.

### Usage:
This script is designed to overlay the indicators (EMAs, VWAP, and Bollinger Bands) on the price chart and plot the ADX below the chart. It helps traders visualize key trends, volatility, and price averages all in one script for more informed trading decisions.
