# Minus Directional Indicator (14) ### Introduction The Minus Directional Indicator (-DI) is a **bearish trend strength indicator** that measures the **strength of downward price movement**. -DI is **primarily bearish** - it provides SHORT signals when values are high and rising, indicating strong downward momentum. This indicator is essential for confirming bearish trends and measuring the conviction behind downward price movements. ### How Minus Directional Indicator (14) Works -DI was developed by J. Welles Wilder Jr. as part of the Directional Movement System. It measures the strength of downward price movement by analyzing negative directional movement relative to the Average True Range (ATR). The calculation involves smoothing negative directional movement over 14 periods and dividing by ATR to create a normalized measure of bearish momentum. Key characteristics of -DI: • **Bearish momentum measurement** - Quantifies the strength of downward price movement\ • **Relative strength indicator** - Compares negative directional movement to volatility\ • **Trending vs ranging identification** - High -DI values indicate strong downward trends\ • **Directional bias confirmation** - When -DI > +DI, bearish bias is confirmed\ • **Momentum acceleration detection** - Rising -DI indicates strengthening bearish momentum {% hint style="info" %} **Market Psychology:** -DI reflects the market's bearish conviction and downward momentum. High -DI values indicate strong selling pressure and sustained downward movement. When -DI is greater than +DI, it shows bears are in control and downward momentum is dominant. {% endhint %} #### Key Characteristics | Attribute | Details | | ---------------- | -------------------------------------------- | | **Category** | Trend Indicators | | **Type** | Bearish Trend Strength Measurement | | **Primary Use** | SHORT entries and bearish trend confirmation | | **Timeframe** | All timeframes supported (1m to 1M) | | **Confirmation** | ADX, volume, momentum indicators | ### Strategy Applications #### 🔴 SHORT STRATEGY (Primary Use) {% hint style="success" %} -DI is primarily a SHORT signal indicator. Use SHORT entries when -DI is high and rising, especially when -DI > +DI, indicating strong bearish momentum and downward trend strength. {% endhint %} **Base Entry Order (SHORT)** ``` Trigger Type: Once per bar close Bar TF: 1H First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Greater Than Second Condition: Plus Directional Indicator (14) Timeframe: 1H ``` **Additional Entry Orders (SHORT)** ``` Additional Entry 1: -DI rising (strengthening bearish momentum) First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Greater Than Second Condition: Simple Moving Average (20) Timeframe: 1H OR Additional Entry 2: Strong bearish momentum with trend confirmation First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Greater Than Second Condition: Value Value: 25 AND First Condition: Average Directional Index (14) Timeframe: 1H Operator: Greater Than Second Condition: Value Value: 25 ``` **Take Profit Orders (SHORT)** ``` Rule 1: Exit condition - Bearish momentum weakening First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Cross Below Second Condition: Plus Directional Indicator (14) Timeframe: 1H OR Rule 2: Exit condition - -DI falling below threshold First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Less Than Second Condition: Value Value: 20 OR Rule 3: Exit condition - Oversold with momentum divergence First Condition: RSI Timeframe: 1H Operator: Less Than Second Condition: Value Value: 25 AND First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Less Than Second Condition: Simple Moving Average (20) Timeframe: 1H ``` **Stop Loss Orders (SHORT)** ``` Rule 1: Stop loss - Bullish momentum dominance First Condition: Plus Directional Indicator (14) Timeframe: 1H Operator: Greater Than Second Condition: Minus Directional Indicator (14) Timeframe: 1H AND First Condition: Average Directional Index (14) Timeframe: 1H Operator: Greater Than Second Condition: Value Value: 20 OR Rule 2: Stop loss - -DI collapse First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Less Than Second Condition: Value Value: 15 OR Rule 3: Stop loss - Volume confirms breakout First Condition: Volume Timeframe: 1H Operator: Greater Than Second Condition: Volume Weighted Moving Average Timeframe: 1H AND First Condition: Minus Directional Indicator (14) Timeframe: 1H Operator: Less Than Second Condition: Plus Directional Indicator (14) Timeframe: 1H ``` #### 🟢 LONG STRATEGY (Secondary Use) {% hint style="warning" %} -DI is not naturally suited for LONG strategies as it measures bearish momentum.
