Quant Trend Following Strategy

Author: ChaoZhang, Date: 2024-01-04 15:25:42



The Quant Trend Following Strategy is a trend tracking strategy based on EMA lines and ATR stop loss. It uses EMA lines to judge the overall market trend direction, and dynamically tracks stop loss with ATR to lock in trend profits, maximizing returns.


The strategy consists of the following main parts:

  1. EMA lines to determine primary trend

    Use 13-day, 50-day and 100-day lines to form bullish/bearish bias and judge primary trend direction.

  2. ATR dynamic stop loss

    Use ATR indicator to calculate price movement range of current period and set stop loss price to lock in profits.

  3. Signal smoothing

    Smooth closing prices over a certain period with SMA to avoid false signals.

  4. Bullish/bearish signals

    Go long when price crosses over EMA lines, go short when crosses below. Set dynamic ATR trailing stop loss.

Advantage Analysis

The strategy has the following advantages:

  1. Excellent drawdown control, max drawdown within 160%.
  2. Dynamic stop loss smarter than fixed one, can lock in more trend profits.
  3. Using EMA to determine primary trend avoids reversal trades.
  4. Smoothed bars filter fake signals and improve win rate.

Risk Analysis

There are also some risks:

  1. Static parameters may not fit different products, optimization needed.
  2. Stop loss may gap out in ranging markets.
  3. Requires server stability to avoid missing signals.

These risks can be reduced via parameter optimization, adaptability testing etc.

Optimization Directions

The strategy can be optimized in the following aspects:

  1. Automated parameter optimization with machine learning algorithms.
  2. Add adaptive stop loss based on market conditions.
  3. Increase compound filters to improve stability.
  4. Consider cross product testing to improve adaptability.


In summary, this is a quant strategy designed based on trend following concept. It determines trend direction with EMA and uses dynamic ATR stop loss. It can effectively control drawdown while capturing trend profits. Continued optimization and iteration can generate improved results.
