Directional Strength and Momentum Index

The Directional Strength and Momentum Index indicator provides a consolidated view of market direction and trend intensity by combining directional strength measurement with momentum analysis into a single index. It aims to offer more clarity than traditional DMI by accounting for candle size and market aggression to identify whether a trend has the necessary "fuel" to sustain its movement.

Usage

The indicator can be used to identify new trends, filter consolidation, and spot potential reversal points. Users can monitor the main DSMI line and the gradient fill between the +DS and -DS lines to gauge market dominance.

• Trend Identification: When the DSMI line rises above the user-defined entry level (default 20) and the +DS line is above -DS, a bullish trend is signaled. Conversely, a bearish trend is signaled when DSMI is above the entry level and -DS is above +DS.
• Entry Signals: Highlighted background areas appear when the DSMI crosses the entry level or when direction changes while the index is already above that level.
• Extreme Zones: Movement into the extreme zones (default 20 and 80) identifies potential overheating or exhaustion, suggesting that a correction or reversal may be imminent.
• Consolidation Filtering: Values below the "Weak" threshold (default 10) turn the indicator gray, indicating a neutral market or consolidation where trading signals are suppressed.

Details

Unlike the classic DMI which uses Wilder smoothing and True Range, the DSMI utilizes exponential moving averages (EMA) and actual candle size (High - Low). This implementation reduces the inherent lag found in traditional trend-following indicators, allowing it to react more dynamically to shifts in market momentum. The calculation yields a normalized index between 0 and 100, which is then categorized into five strength levels: Weak, Moderate, Strong, Overheated, and Extreme.

Settings

Extreme Zones

• Lower/Upper Extreme Level: Defines the thresholds for the extreme gradient zones.

Trend Strength Levels

• Weak/Moderate/Strong/Overheated Trend: Adjustable thresholds used to categorize the current trend intensity in the dashboard and visual output.

Entry Signals

• Show Entry Signal Highlight: Enables or disables the green/red background highlights for trade signals.
• DSMI Entry Level: The minimum index value required to trigger an entry signal.

Additional Options

• Trend Colors: Customization for bullish, bearish, and neutral color schemes.
• Color Candles by Trend: When enabled, price bars are colored based on the current DSMI trend state.

FAQ

How do I interpret the trend strength table?

The table in the top-right corner provides a real-time summary of the DSMI value and its corresponding strength category, helping you quickly identify if the market is trending strongly or in a state of exhaustion.

What is the difference between DSMI and traditional ADX/DMI?

The DSMI replaces True Range with candle size and uses EMA instead of Wilder smoothing, resulting in faster reactions to price action and a more sensitive measurement of directional momentum.
