Strategy Description
[trans]
概述
该策略是利用方向趋势指数(DTI)判断价格趋势走向并进行趋势跟踪的交易系统。DTI通过比较一定周期内最高价和最低价的变化方向来判断趋势,并设定上下阈值来产生交易信号。当DTI上穿上轨时做多,下穿下轨时做空。
策略原理
计算一定周期内的最高价变化和最低价变化,得到价格变化值。对价格变化值进行多次指数移动平均,得到DTI曲线。设定DTI的上下阈值,当指标上穿上阈值时产生做多信号,下穿下阈值时产生做空信号,一直持有至下一信号出现。
优势分析
- DTI判断趋势方向准确、信号较少
- 采用阈值过滤无效突破,避免噪音交易
- 持续跟踪趋势,不受短期波动影响
- 参数调整空间大,可平衡反应灵敏度
风险分析
- 无法准确判断趋势反转点,存在亏损风险
- DTI参数设置不当可能漏失交易机会
- 长期持仓可能带来较大回撤
- 交易频次较低,不适合高频交易
可适当缩短计算周期,调整阈值参数,或结合其他指标判断趋势反转。
优化方向
- 测试计算DTI的不同参数组合
- 优化DTI做多做空的阈值
- 考虑设置止损策略控制风险
- 在不同品种中测试参数健壮性
总结
DTI策略通过清晰的指标信号判断趋势方向,可实现长线稳定盈利。通过参数优化等进一步改进,可成为优质的趋势跟踪策略。

Overview
This strategy uses the Directional Trend Index (DTI) to determine price trend direction for trend following trades. DTI compares the change in highest and lowest prices over a period to judge the trend, with upper and lower thresholds generating signals. Go long when DTI crosses above upper band, and short when crossing below lower band.
Strategy Logic
Calculate price change value from highest and lowest price changes over a period. Apply multiple exponential moving averages to this to derive the DTI curve. Set upper and lower thresholds for DTI. When the indicator crosses above the upper threshold, a long signal is generated. Crossing below the lower threshold gives a short signal. Hold position until next signal occurs.
Advantages
- DTI accurately determines trend direction with fewer signals
- Thresholds filter insignificant breakouts avoiding noise trades
- Continuously following trends, unaffected by short-term fluctuations
- Large parameter tuning space to balance responsiveness
Risks
- Trend reversal points cannot be accurately determined, risks losses
- Poor DTI parameter tuning risks missing opportunities
- Prolonged holding may result in larger drawdowns
- Low trade frequency unsuitable for high frequency trading
Risks can be mitigated by shortening calculation period, adjusting thresholds, or adding reversal indicators.
Enhancements
- Test different parameter combinations for calculating DTI
- Optimize long/short threshold levels
- Consider adding stop loss strategies to control risk
- Test robustness across different products
Conclusion
DTI strategy accurately determines trend direction from clear signals, enabling steady long-term profits. Further refinements like parameter optimization can make it a high-quality trend following system.

// This technique was described by William Blau in his book "Momentum,
// Direction and Divergence" (1995). His book focuses on three key aspects
// of trading: momentum, direction and divergence. Blau, who was an electrical
// engineer before becoming a trader, thoroughly examines the relationship between
// price and momentum in step-by-step examples. From this grounding, he then looks
// at the deficiencies in other oscillators and introduces some innovative techniques,
// including a fresh twist on Stochastics. On directional issues, he analyzes the
// intricacies of ADX and offers a unique approach to help define trending and
// non-trending periods.
// Directional Trend Index is an indicator similar to DM+ developed by Welles Wilder.
// The DM+ (a part of Directional Movement System which includes both DM+ and
// DM- indicators) indicator helps determine if a security is "trending." William
// Blau added to it a zeroline, relative to which the indicator is deemed positive or
// negative. A stable uptrend is a period when the DTI value is positive and rising, a
// downtrend when it is negative and falling.
//
// You can change long to short in the Input Settings
// Please, use it only for learning or paper trading. Do not for real trading.
