The Two Fundamental Approaches

Every trading strategy, no matter how complex, is fundamentally based on one of two beliefs about price behavior:

1. Mean reversion: prices tend to return to an average. If something has gone up too much, it will come back down. If it has dropped too far, it will bounce back.

2. Momentum: prices tend to continue in their current direction. Things going up tend to keep going up. Things going down tend to keep going down.

These two approaches are in direct conflict, and both are correct — but at different times and on different timeframes. The art of algorithmic trading is knowing when each regime is active and deploying the appropriate strategy.

FerroQuant's 165+ strategy library includes both types, and the Cascade Weighting strategy dynamically adjusts between them based on detected market regime.

Mean Reversion Strategies

Mean reversion strategies profit when prices snap back to a central tendency. The classic indicators for mean reversion are:

- RSI (Relative Strength Index): when RSI drops below 30 (oversold), the strategy expects a bounce. When above 70 (overbought), it expects a pullback. - Bollinger Bands: when price touches or penetrates the lower band, it is expected to revert to the middle band (20-period moving average). Upper band touches suggest a pullback. - VWAP Reversion: when price deviates significantly from the Volume-Weighted Average Price, it tends to revert during the same trading session.

FerroQuant strategies that use mean reversion: RSI Crossback, RSI + Bollinger Bands, Bollinger Breakout (on band reversion), and VWAP Reversion.

Mean reversion works best in ranging markets — when price is oscillating between support and resistance without a clear trend. It fails spectacularly during strong trends, where "oversold" can become "more oversold" for weeks (this is why stop-losses are non-negotiable).

Momentum Strategies

Momentum strategies profit from trends continuing. The key indicators are:

- MACD (Moving Average Convergence Divergence): a MACD crossover signals momentum direction changes. When the MACD line crosses above the signal line, bullish momentum is building. - Moving Average crossovers: when a short-term MA (e.g., EMA-20) crosses above a long-term MA (e.g., EMA-50), it signals a trend change. - Breakout levels: when price breaks through established support or resistance with volume, momentum strategies enter in the direction of the break.

FerroQuant strategies that use momentum: MACD Crossover, Momentum Breakout, and MACD + Bollinger Bands.

Momentum works best in trending markets — during strong uptrends, downtrends, or after consolidation breakouts. It fails in choppy, range-bound markets where false breakouts generate losses on both sides.

Combining Both: Adaptive Strategies

The most sophisticated approach is to detect the current market regime and deploy the appropriate strategy type.

FerroQuant's Cascade Weighting strategy does exactly this. It uses a lookback window to measure recent price behavior and assigns dynamic weights to each indicator. In trending markets (detected by ADX > 25 or sustained MA slope), momentum indicators receive higher weight. In ranging markets (low ADX, price contained within Bollinger Bands), mean reversion indicators are prioritized.

The Synergistic Confluence strategy takes a different approach: it requires agreement from both mean reversion AND momentum indicators. A long signal requires RSI to be in an extreme zone (mean reversion setup) while MACD shows a bullish crossover (momentum confirmation). This dual requirement produces fewer but higher-quality signals.

The Triple Indicator strategy (RSI + MACD + Bollinger Bands) is the most conservative, requiring all three indicators — spanning both strategy types — to agree before entering. This extreme filtering produces the highest win rate in the FerroQuant library but with significantly fewer trade opportunities.

Which Type Should You Trade?

For beginners, start with mean reversion strategies. They are more intuitive (buy low, sell high), have clearer entry and exit levels, and typically have higher win rates (though smaller average wins).

As you gain experience, add momentum strategies to capture larger moves. The ideal portfolio uses both:

- Mean reversion strategies for income: frequent small wins in ranging markets - Momentum strategies for growth: occasional large wins during trend breakouts - Adaptive strategies for consistency: automatic switching between regimes

FerroQuant runs all strategy types simultaneously across all symbols. When a symbol enters a strong trend, the momentum strategies capture it. When it ranges, the mean reversion strategies profit. The diversification across strategy types is just as important as diversification across symbols and markets.
