ADX / DMI(+)(-) TRENDICATOR

## Draft Description

**ADX / DMI(+)(-) TRENDICATOR** is a responsive trend-strength and directional-momentum indicator designed to complement an **8 EMA / 20 EMA trading system**.

It combines:

- **ADX** to measure trend strength
- **DI+** to measure bullish directional pressure
- **DI−** to measure bearish directional pressure
- **20 and 40 ADX levels** to identify developing and strong trends
- **Angel Crosses** when DI+ crosses above DI−
- **Death Crosses** when DI− crosses above DI+
- Confirmed-candle alerts designed to avoid intrabar repainting

The default calculation settings use an **8-period DI length** and **8-period ADX smoothing** for a faster response to recent price candles. All calculation settings remain adjustable for different markets and timeframes.

The indicator includes customizable:

- ADX, DI+, and DI− visibility
- ADX and DI line widths
- Line, stepline, and circle plot styles
- Indicator colors
- Horizontal level visibility and styles
- ADX alert threshold
- Directional DI fill

Use ADX to determine whether a market is trending, then use DI+ and DI− to identify the dominant directional pressure. For example, a bullish EMA alignment combined with DI+ above DI− and ADX above 20 may indicate strengthening bullish momentum.

## How It Differs From Typical ADX/DMI Indicators

### 1. Confirmed-candle behavior

Many indicators react to changing intrabar values, causing temporary crosses or signals that can disappear before the candle closes. This indicator commits ADX, DI+, and DI− values only after candle confirmation, helping prevent intrabar signal repainting.

### 2. Designed for faster EMA-based systems

The default **8/8 settings** are intended as a responsive starting point for an **8 EMA / 20 EMA trend system**, rather than relying exclusively on the traditional slower 14/14 settings.

### 3. Clearer trend-strength framework

The fixed **20 and 40 levels** provide a simple visual framework:

- Below 20: weak or ranging conditions
- Above 20: trend development or moderate strength
- Above 40: strong trend conditions

### 4. More complete customization

Instead of only changing colors, users can control visibility, line widths, plot styles, level styles, and directional fills directly from the settings panel.

### 5. Expanded alert system

The indicator includes confirmed alerts for:

- Angel Crosses
- Death Crosses
- ADX crossing above or below 20
- ADX crossing above or below 40
- ADX crossing the custom alert threshold

### 6. Direction and strength are separated

Unlike systems that treat ADX as a buy or sell signal, this indicator keeps the concepts separate:

- **ADX = strength**
- **DI+ / DI− = direction**
- **8 EMA / 20 EMA = trend structure**

This helps reduce the common mistake of interpreting a rising ADX alone as a bullish signal.
