## 📈 Detailed Guide to the Round Number Zones Indicator

### Core Concept

This indicator automatically identifies and highlights key psychological price levels on your chart. Traders and institutions often place orders around "round numbers" (like $100, $50, or $25), which causes these levels to act as natural areas of support and resistance. This script saves you the manual work of finding and drawing these important zones.

### How It Works

The indicator operates by finding the current price and then calculating the nearest multiples of 100, 50, and 25 around it. It then draws colored zones to visually represent these levels.

* **Primary Zones (Multiples of 100):** These are the strongest psychological levels (e.g., 6500, 6600, 6700). They are shown in blue by default and have the largest zone size.
* **Secondary Zones (Multiples of 50):** These are intermediate levels (e.g., 6550, 6650). They are shown in gray by default.
* **Tertiary Zones (Multiples of 25):** These are minor, short-term levels (e.g., 6525, 6575). They are shown in yellow by default.

The indicator is "smart"—it will not draw a 50-level zone if it's already a 100-level, and it won't draw a 25-level if it's already a 50 or 100. This keeps your chart clean and easy to read.

### How to Use It in Your Trading

* **Support & Resistance:** The primary use is to identify potential S/R. When the price approaches one of these zones, expect a reaction. A wider, primary (100) zone is a stronger level than a smaller, tertiary (25) zone.
* **Entry and Exit Targets:** Use these zones as logical places to take profit or to look for entry signals. For example, a bullish rejection candle forming in a 100-level support zone can be a powerful long signal.
* **Confluence:** The zones are most effective when they align with other technical analysis tools, such as moving averages, trendlines, or Fibonacci levels. A confluence of signals at a round number zone significantly increases its importance.

### ⚙️ Indicator Settings

You have full control over the indicator's appearance through its settings menu (click the ⚙️ icon):

* **Show Levels:** Each level type (100, 50, 25) can be turned on or off individually.
* **Number of Levels Above/Below:** Controls how many zones are drawn around the current price. You can reduce this number to declutter your chart or increase it to see a wider range.
* **Zone Size (+/-):** This determines the thickness of the colored zone around the round number, allowing you to define a wider or tighter area of interest.
* **Zone Color:** Fully customize the colors of each zone type to match your chart's theme.
