This strategy uses the Absolute Price Oscillator (APO) indicator to generate trading signals and follow trends. The APO calculates the difference between two EMAs and trades crossovers above/below zero.
APO consists of a faster and slower EMA, taking the difference between them.
When APO crosses above the buy zone (default 3), go long. When it crosses below the sell zone (default -3), go short.
Option to reverse signals - cross above sells, cross below buys.
Curve shows price momentum, can find reversals on divergence.
This is a trend following strategy, using APO to determine trend direction for sustained long/short signals. Optimized parameters can track medium-term trends.
Simple implementation using basic moving average combination.
APO gauges price momentum and direction.
Default parameters generate medium-term sustained signals, avoiding over-trading.
Can detect trend reversals based on price/indicator divergence.
Prone to false signals and whipsaws in ranging markets.
Lagging signals may miss quick reversals.
No stop loss or position sizing, incomplete risk management.
Mitigations:
Optimize parameters and test different combinations per instrument.
Add filters to avoid trading in choppy conditions.
Implement stop loss, e.g. trailing stop.
Parameter optimization for each instrument to find ideal pairs.
Additional filters on price action or volume to reduce false signals.
Dynamic position sizing based on volatility or account %.
Optimized take profit such as trailing stop to follow trends.
ML to assess probability of successful divergence signals.
This EMA crossover system using APO provides a solid foundation for trend following. With optimizations in parameters, risk management and filters, it can become an effective quantitative strategy. The core concept is simple and robust for further development.

// The Absolute Price Oscillator displays the difference between two exponential
// moving averages of a security's price and is expressed as an absolute value.
// How this indicator works
// APO crossing above zero is considered bullish, while crossing below zero is bearish.
// A positive indicator value indicates an upward movement, while negative readings
// signal a downward trend.
// Divergences form when a new high or low in price is not confirmed by the Absolute Price
// Oscillator (APO). A bullish divergence forms when price make a lower low, but the APO
// forms a higher low. This indicates less downward momentum that could foreshadow a bullish
// reversal. A bearish divergence forms when price makes a higher high, but the APO forms a
// lower high. This shows less upward momentum that could foreshadow a bearish reversal.
