Overview

This strategy combines two mainstream technical indicators: the Oma indicator and the Apollo indicator to implement dual-rail trading of long and short positions. Its basic idea is to find short-term pullback opportunities when the medium-long term trend is judged to be bullish in order to establish long positions. When the medium-long term trend is judged to be bearish, it looks for opportunities in short-term rebounds to establish short positions.

Strategy Principle

This strategy uses 50-day and 200-day moving averages to determine the medium-long term trend. The 50-day line above the 200-day line indicates a bullish trend, and vice versa for a bearish trend.

Next, the strategy uses the Oma indicator to locate short-term price reversal opportunities. The Oma indicator includes %K and %D lines, which are the results of the RSI indicator smoothed by a simple moving average. When %K breaks below %D from the overbought area (above 80), it indicates the price is turning from an overbought state to a pullback down; when %K breaks above %D from the oversold area (below 20), it indicates the price is rebounding up from the oversold area, which presents a long opportunity.

In addition, to further filter false signals, this strategy also incorporates the Apollo indicator. The Apollo indicator displays the extreme points of the %D values of the K line. When %K forms a new low, it means the rebound strength is relatively weak. When it forms a new high, it means the rebound strength is relatively strong. Combined with the signals from the Oma indicator, this can further improve the accuracy of entry.

Specifically, in an uptrend, this strategy will check the new high point information at the same time when the Oma indicator shows an opportunity below the overbought area, to confirm the strength of the bounce. In a downtrend, when the Oma indicator shows a short opportunity crossing up from the oversold area, this strategy will check the new low point information at the same time to confirm the weakening of the rebound strength.

Through the above process, this strategy takes full advantage of the strengths of medium-long term trend judgment and short-term reversal indicators to build a steady dual-rail trading system.

Advantages of the Strategy

The strategy combines trend trading and countertrend trading by using both trend judgment and reversal indicators, forming a stable hybrid trading framework.
By double indicator filtering, the false signal ratio can be reduced and the reliability of signals improved.
The strategy parameters are relatively simple, easy to understand and optimize, suitable for quantitative trading.
The performance of the strategy is robust, with good win rate and risk-reward ratio characteristics.
By adopting dual rails for long and short, trading opportunities can be obtained continuously without being limited to a single direction.

Risks of the Strategy

As a reversal strategy, consecutive losses may occur when the trend changes.
The strategy requires relatively high emotional control from the trader, who needs to withstand a certain level of drawdown.
Some parameters such as moving average periods involve a certain subjectivity and need to be determined through backtesting and optimization.
Both the Oma and Apollo indicators have some sensitivity to abnormal fluctuations, and may fail in extreme market conditions.
This strategy is more suitable for range-bound volatile markets, and may underperform in strong trending markets.

Risks can be mitigated by appropriately adjusting the moving average period to introduce trend filtering, and adding stop loss/take profit. When the market becomes strongly trending, consider suspending the strategy to avoid trading in that environment.

Optimization Directions

Test different parameter combinations to obtain better parameter settings, e.g. using EWMA smoothing moving averages.
Add Volume or BV indicators to judge divergence which can help verify signal reliability.
Add volatility indices like VIX as monitoring indicators, to reduce position size when the market is in panic.
Optimize stop loss/take profit strategies, such as adopting dynamic ATR stop loss.
Introduce machine learning algorithms to dynamically optimize parameter settings.
Add multifactor models to improve signal quality.

Summary

Overall, this is a stable and efficient quantitative trading strategy. It combines trend judgment and reversal indicators, and adopts dual verification using the Oma and Apollo indicators, which can effectively uncover short-term price reversal opportunities. Compared to using purely trend or reversal systems, this strategy form is more robust with superior drawdown control, and is a recommended quantitative trading strategy. Of course, users also need to be aware of the risks involved, and use parameter optimization, stop loss/take profit, market regime identification etc. to control risks and achieve the best performance.
