Momentum Trend-Following Strategy

Author: ChaoZhang, Date: 2024-03-11 10:53:50



This strategy combines the Aroon indicator and the Absolute Strength Histogram (ASH) to identify market trends and potential trading opportunities. Aroon helps determine the strength and direction of trends, while ASH provides insights into the momentum strength. By combining these indicators, the strategy aims to capture profitable trades in Ethereum markets.

Strategy Logic

The strategy uses two sets of parameters for the Aroon indicator:

  • Long Positions: Aroon periods are 56 (upper) and 20 (lower)
  • Short Positions: Aroon periods are 17 (upper) and 55 (lower)

The ASH is calculated with a length of 9 bars using the closing price as the data source.

The strategy incorporates specific entry and exit rules:

  1. Long Entry: A long position is initiated when the Aroon indicator crosses over the lower threshold, signaling a potential uptrend.
  2. Long Exit: A long position is closed when the Aroon crosses back under the lower threshold.
  3. Short Entry: A short position is initiated when the Aroon crosses under the upper threshold, signaling a potential downtrend.
  4. Short Exit: A short position is closed when the Aroon crosses back over the upper threshold.

Advantage Analysis

The main advantage of this strategy is the synergy from combining the two indicators. Aroon effectively gauges trend direction and strength. ASH provides additional momentum insights to aid with timing entry and exit signals.

Using two Aroon parameters allows flexibility in adapting to changing market conditions.

Risk Analysis

The main limitations stem from the indicators themselves. Aroon struggles during range-bound markets and can generate false signals. ASH is also prone to overreactions in the short term.

Inappropriate parameter settings could also impact performance. The long/short periods of Aroon and length of ASH would need optimization to find the ideal combinations.

Improvement Directions

Additional filters could be added, such as price breakouts or rising volumes, to avoid false signals during choppy conditions.

Different parameter combinations and weights could be tested to find optimal settings. Other indicators like RSI or KD could also complement the strategy.


The strategy effectively combines the strengths of Aroon and ASH for dual-confirmation of trends and turning points. But parameters and indicator limitations still need refinement. The creative concept shows promise for further improvements and testing.
