EA Portfolio Strategies to Navigate Market Volatility: Anomaly, Trend-Following, Contrarian, and Multi-Logic Approaches

Building an EA portfolio is essential for achieving stable returns in the forex market. By combining different EAs with diverse strategies, you can mitigate risk and enhance overall performance.

There are four main types of EAs:

Anomaly-Based: These EAs rely on specific rules derived from time, rate, and other non-technical indicators to enter and exit trades.

Trend-Following: These EAs follow the prevailing market trend, buying when prices are rising and selling when they’re falling.

Counter-Trend: These EAs aim to identify and capitalize on market reversals.

Multi-Logic: These EAs combine multiple trading strategies to achieve a more balanced and robust approach.

Personal Experience with Anomaly-Based EAs.

I’ve been developing EAs since 2020, and I initially focused on Anomaly-Based strategies. However, I found that simple anomalies often prove ineffective in forex trading. While specific logics like Tokyo Interbank Rate or London Fix may hold promise, it’s crucial to select EAs with recent positive forward performance.

Trend-Following vs. Counter-Trend.

By nature, Trend-Following EAs excel in trending markets, while Counter-Trend EAs thrive in ranging markets. I attempted to combine both types in the past, but the strategy proved unsuccessful, especially in the volatile market conditions since 2020. Counter-Trend EAs tend to incur losses during such periods. Therefore, it’s advisable to limit their use in trend-dominated markets like the current one.

Introducing Reversal Seven.

Reversal Seven

Reversal Seven is my signature Counter-Trend EA, utilizing multiple logics and supporting up to three positions on the 5-minute chart for the Dollar/Yen pair. It’s based on seven reversal techniques and represents my best work in this category. During the recent Bank of Japan intervention, Reversal Seven held opposite positions compared to Trend-Following EAs, effectively diversifying risk.

Trend-Following EAs.

Trend-Following EAs are particularly well-suited for the current market environment. The key to success lies in identifying high-performing Trend-Following EAs.

Multi-Logic EAs: Leveraging Combined Strategies.

Initially, I focused on Anomaly-Based EAs, followed by Trend-Following and Counter-Trend strategies. Currently, I’m primarily developing Multi-Logic EAs, drawing upon my accumulated expertise. This approach offers the significant advantage of simplifying EA portfolio construction by combining Trend-Following, Counter-Trend, and Anomaly-Based elements.

Introducing Seven Elements.

Seven Elements

Seven Elements is my most confident EA, featuring multiple logics and supporting up to three positions for both the Dollar/Yen and Pound/Yen pairs. Currently, seven of its ten logics are Trend-Following, reflecting the favorable market conditions. In the future, I plan to incorporate Counter-Trend and Anomaly-Based logics to adapt to various market scenarios. If you’re seeking reliable EAs, consider Seven Elements.


Building an EA portfolio is a common practice among successful EA traders. For maximum compounding, consider single or multi-position EAs and prioritize strategies with diverse logics.
