Overview

Strategy Logic

The strategy consists of three main parts:

Supertrend Indicator: Calculates the up breakout line and down breakout line to determine the current trend direction. It generates buy signals when the price breaks out upwards from the supertrend line, and sell signals when the price breaks out downwards.
Double Exponential Moving Average (DEMA): A trend tracking indicator that combines the features of simple moving average and exponential moving average, which can respond to price changes faster. The strategy sets a 200-day DEMA to judge the long-term trend direction.
Bollinger Bands: Represents the fluctuation range of prices. Abnormal contraction or expansion of Bollinger Bands signals potential trend reversals.

When the Supertrend indicator and DEMA both issue buy/sell signals, the strategy enters the corresponding position. In addition, anomalies of Bollinger Bands can serve as auxiliary judgment signals.

Advantages

Combination of multiple indicators reduces false signals.
Supertrend indicator is insensitive to minor price changes and only generates signals at trend turning points, avoiding excessive frequency of trading.
DEMA smooth curve accurately and reliably judges long-term trends.
Bollinger Bands assist in determining trend reversal points.

Risks and Solutions

Overly sensitive supertrend parameters may generate more noise. Optimizing the ATR period and multiplier parameters can improve it.
Long DEMA period results in poor trend following capability. Can test shortened periods like 100-day.
Inconsistent signals when combining judgment of multiple indicators. In this case, the supertrend indicator can be considered the primary signal.

Optimization Directions

Test different ATR periods and multiplier parameters to find the optimal combination for the supertrend indicator.
Optimize the DEMA period parameter.
Add other auxiliary indicators like KDJ, MACD etc.
Introduce stop loss strategies.

Summary

The Dual Trend Tracking Strategy combines the strengths of Supertrend, DEMA and Bollinger Bands by using multiple indicators, improving signal quality while capturing trends. Further performance improvements can be expected through parameter optimization and adding stop loss mechanisms.
