5 EMA Suite

Here is a breakdown of the code logic, tailored to your background as a developer.

### 1\. Version & Declaration

```pinescript
//version=6
indicator("5 EMA Suite", shorttitle="5 EMA", overlay=true)
```

* **`//version=6`**: This is the compiler directive. It tells TradingView to use the latest Pine Script engine (v6).
* **`indicator(...)`**: This defines the script properties.
* `"5 EMA Suite"`: The full name seen in the library.
* `shorttitle="5 EMA"`: The label seen on the chart legend.
* `overlay=true`: This is crucial. It tells the script to draw **on top of the price candles**. If this were `false`, the lines would appear in a separate pane below the chart (like an RSI or MACD volume oscillator).

### 2\. User Inputs (The "Settings" UI)

```pinescript
group_settings = "EMA Configurations"

len1 = input.int(9, title="EMA 1 Length", minval=1, group=group_settings)
...
src = input.source(close, title="Source", group=group_settings)
```

* **`input.int(...)`**: This creates an integer field in the UI settings menu. It’s similar to defining public properties in a .NET class that a user can configure at runtime.
* **`9`**: The default value.
* **`minval=1`**: Input validation (prevents divide-by-zero or negative length errors).
* **`group`**: Organizes all these inputs under a collapsible header in the settings menu, keeping the UI clean.
* **`input.source(...)`**: Allows you to choose what data to calculate on (e.g., `close`, `open`, `high`). Default is `close`.

### 3\. The Calculation Logic

```pinescript
ema1 = ta.ema(src, len1)
```

* **`ta.ema`**: This calls the built-in **Technical Analysis** namespace (`ta`).
* It calculates the Exponential Moving Average using the `src` (Price) and `len1` (Lookback period) defined above.
* Pine Script handles the array/series processing automatically. You don't need a `for` loop to iterate through historical bars; the runtime executes this script once for every bar on the chart efficiently.

### 4\. Visualization (Plotting)

```pinescript
plot(ema1, color=color.new(color.blue, 0), title="EMA 1", linewidth=1)
```

* **`plot(...)`**: The command to render the data on the canvas.
* **`color.new(color.blue, 0)`**: In v6, you cannot pass transparency directly to `plot`. You must create a color object.
* `color.blue`: The base color.
* `0`: The transparency (0 = solid/opaque, 100 = invisible).
* **`linewidth`**: Sets the thickness of the line (pixels). I increased the thickness for higher EMAs (50, 100, 200) in the code so visually they stand out as "major" support/resistance levels.
