The world of technical analysis is constantly evolving, with traders and developers creating innovative tools to gain an edge in the markets. Two such examples are the RedK Directional Index (K xDMI) and a modified MACD strategy, both built on TradingView's Pine Script platform. These tools demonstrate how classic indicators can be adapted for modern trading needs.
Understanding the RedK Directional Index (K xDMI)
The RedK Directional Index offers a contemporary reinterpretation of the famous DMI/ADX indicator system. At its core, this enhanced version maintains the fundamental principles while introducing several improvements that make it more responsive and visually intuitive for today's traders.
Core Components of Traditional DMI/ADX
Traditional Directional Movement Index systems consist of three primary elements:
- Plus Directional Index (+DI): Measures bullish momentum by quantifying how effectively buyers push prices higher
- Minus Directional Index (-DI): Measures bearish momentum by showing how effectively sellers push prices lower
- Average Directional Index (ADX): An oscillator derived from the DI values that indicates trend strength regardless of direction
Key Enhancements in the K xDMI
This modernized version introduces several significant improvements over the classic indicator:
1. Improved ADX Visualization
The most notable change involves how the ADX component is calculated and displayed. Unlike the traditional approach that restricted ADX oscillation below zero, the K xDMI allows the ADX to oscillate both above and below zero. This provides a more intuitive representation of trend strength, particularly during bearish market conditions.
2. Refined Calculation Methodology
Instead of applying multiple moving averages as in the classic calculation, this version smooths the initial +DI and -DI values before calculating the ADX. This approach keeps the indicator more closely connected to recent price action rather than being "removed" from base price values.
3. Weighted Moving Averages
The indicator utilizes Weighted Moving Average (WMA) calculations throughout, which places greater emphasis on recent price data compared to older information. This weighting better reflects the relevance of current market conditions in fast-moving markets.
4. Optional Volume Weighting
While not enabled by default, the K xDMI offers an optional volume-weighting feature that incorporates trading volume into the directional movement calculations.
Visualization Options and Customization
The indicator provides multiple viewing options to suit different analytical preferences:
- Area charts for smooth visualization of trend strength
- Histogram/column displays (called Vertical Bars) for clearer oscillation patterns
- Adjustable "step" settings that allow traders to view trend strength in qualitative terms (weak, medium, strong) rather than precise numerical values
- Customizable "strong trend" levels that act as filters for trade signals
Practical Application and Settings
The developer recommends using default settings (length = 7, smoothing = 3) which are optimized for today's faster-paced markets. From a signal perspective, traders can use the K xDMI similarly to the classic version:
- Bullish signals occur when +DI crosses above -DI while simultaneously moving above the user-defined "strong trend" level (typically between 20-30)
- Bearish signals occur when -DI crosses above +DI while exceeding the strong trend threshold
- The ADX component continues to indicate trend quality and strength

As with any technical indicator, the K xDMI should be used in conjunction with other confirmation tools and broader timeframe analysis to validate trading decisions.
Modified MACD Strategy for Modern Backtesting
Another innovative approach involves a strategically modified MACD (Moving Average Convergence Divergence) system designed specifically for backtesting from 2015 onward.
Key Modifications
This MACD variation introduces two significant changes to the standard TradingView strategy:
1. Time-Restricted Backtesting
The strategy includes a "year>2014" condition in buy/sell logic, ensuring that all backtesting results reflect market behavior from 2015 forward. This approach acknowledges that market dynamics have evolved and that older data may not be relevant to current conditions.
2. Parameter Doubling Technique
The developer discovered that standard MACD settings often generated late signals. To address this, the strategy uses doubled parameter values (e.g., 20, 42, 20 instead of the traditional 10, 21, 10). This effectively makes a 30-minute interval perform similarly to a 1-hour chart with standard settings.
Practical Implementation and Results
This parameter adjustment technique offers several advantages:
- Reduces noise on shorter timeframes while maintaining responsiveness
- Allows traders to effectively view higher timeframe dynamics on lower timeframe charts
- Enables more meaningful backtesting on shorter intervals
The developer reports testing this approach on cryptocurrency markets using 45-minute charts (effectively representing 90-minute intervals with the doubled parameters), achieving a 42% profitability rate and 1.998 profit factor across 189 trades.
For even smoother results, some traders prefer tripling the parameters (30, 63, 30), which effectively converts a 15-minute chart view into 45-minute strategy logic or a 30-minute chart into 1.5-hour strategy logic.
Integrating These Tools Into Your Trading Strategy
Both the K xDMI and modified MACD approach demonstrate how traditional technical indicators can be adapted for contemporary market conditions. When incorporating these tools into your trading approach, consider these best practices:
1. Multi-Timeframe Analysis
Always validate signals across multiple timeframes to ensure you're trading in the direction of the broader trend.
2. Confirmation with Complementary Indicators
Use these tools alongside other technical indicators such as support/resistance levels, volume analysis, or momentum oscillators for higher-probability trades.
3. Appropriate Parameter Optimization
Experiment with different settings to find what works best for your specific trading instrument and timeframe preferences.
4. Rigorous Backtesting
Thoroughly test any strategy across various market conditions before committing real capital, paying particular attention to drawdown periods and worst-case scenarios.
5. Risk Management
Implement proper position sizing and stop-loss strategies regardless of how promising any indicator signals appear.

Frequently Asked Questions
What makes the K xDMI different from traditional DMI/ADX indicators?
The K xDMI introduces several enhancements including improved ADX visualization that oscillates above and below zero, refined calculation methodology that stays closer to price action, weighted moving averages that emphasize recent data, and optional volume weighting. These changes make the indicator more responsive to current market conditions.
How does the parameter doubling technique work in the modified MACD strategy?
By doubling the standard MACD parameters (fast length, slow length, and signal smoothing), traders can effectively make lower timeframe charts behave like higher timeframe analysis. For example, a 30-minute chart with doubled parameters responds similarly to a 1-hour chart with standard settings, reducing noise while maintaining responsiveness.
Can these indicators be used for all financial markets?
While both tools were designed with flexibility in mind, their effectiveness may vary across different markets. The K xDMI has broad applicability across stocks, forex, and cryptocurrencies, while the modified MACD approach has shown particular promise in cryptocurrency markets. Always test thoroughly in your specific market before implementation.
Why restrict backtesting to post-2014 data?
Financial markets have undergone significant structural changes in recent years, including increased algorithmic trading, changing regulatory environments, and new market participants. Restricting backtesting to more recent data helps ensure that results reflect current market dynamics rather than historical conditions that may no longer be relevant.
How important is it to use these indicators with other confirmation tools?
Extremely important. No single indicator should be used in isolation for trading decisions. Both developers emphasize using their tools alongside other technical analysis methods, price action analysis, and broader market context to validate signals and improve probability.
Are these strategies suitable for beginner traders?
While the concepts behind these tools are based on established technical indicators, the modifications introduce additional complexity. Beginner traders should first develop a solid understanding of the underlying DMI/ADX and MACD concepts before implementing these enhanced versions. Paper trading and thorough backtesting are strongly recommended.
