Price Action Strategy

Overview

This is a trading strategy based on price action, combined with moving averages to identify trends and using price patterns for entry.

Strategy Principles

The strategy is mainly based on the following aspects:

  1. Using EMA to judge trends. When 89-period EMA and Hull MA are both red, it is judged as a Bear trend, go short only; when both are green, it is judged as a Bull trend, go long only; when one is green and one is red, it is judged as consolidation, both long and short are possible.

  2. Identifying signals with price patterns. The strategy recognizes various candlestick combinations like single candles, fakey patterns, inside bars etc. to spot potential entry points.

  3. Combining with key support/resistance levels for entry. The strategy also incorporates key S/R levels to further verify price pattern signals and avoid false breakouts.

  4. MACD as confirmation. MACD histogram colors are used to confirm price pattern signals and improve probability.

  5. Trend following mechanism. The strategy includes a trend following module to more accurately detect trend reversals and avoid chasing tops and bottoms.

  6. Setting stop loss and take profit. Fixed stop loss and take profit based on ATR are included to manage risk/reward.

Advantage Analysis

The strategy has the following advantages:

  1. Based on price action, unaffected by indicators. Pure price-based without complex indicators, closer to market nature.

  2. Combining trends, avoiding chasing. EMA and Hull MA identify trend direction, operating along trends, avoiding counter-trend trades.

  3. Pattern + indicator improves probability. Price patterns combined with MACD verifies signals, filters false signals, improving profitability.

  4. Trend following catches big moves. Trend following module catches larger time frame trends, with greater profit potential.

  5. Stop loss/take profit controls risk. Fixed stop loss/take profit ratios help manage risk/reward.

Risk Analysis

The strategy also has the following risks:

  1. Larger time frame trend reversal risk. The strategy works best with clear mid/short-term trends. Larger reversal risks being stopped out. Larger time frame analysis can help avoid.

  2. Price pattern failure risk. Price patterns have varying effectiveness in different market environments. Some markets can cause patterns to fail, leading to losses. Backtesting various markets can optimize pattern selection.

  3. Parameter optimization difficulty. The strategy has multiple parameters. Different combinations impact results significantly. Extensive backtesting required to find optimal parameters. Static setting also risks market regime changes. A dynamic parameter optimization mechanism can help address this.

  4. Inability to control individual trade risk. Fixed stop loss/take profit cannot adapt to fluctuations in each trade and manage individual trade risk/reward ratios. Dynamic stop loss algorithms or risk management modules can help.

Optimization Directions

The strategy can be improved in the following aspects:

  1. Introduce machine learning for more complex pattern recognition. Use deep learning etc. to automatically detect more effective patterns.

  2. Increase adaptiveness. Build dynamic parameter optimization mechanisms so the strategy can adjust based on real-time market conditions rather than static settings.

  3. Incorporate more factors to verify signals. Add more price action factors like volume, overnight gaps etc. to confirm signals and reduce risk of being trapped.

  4. Introduce risk management and position sizing. Automatically adjust position sizes based on thresholds to effectively control single trade stop loss and optimize risk/reward ratios.

  5. Optimize entry mechanisms. Refine trend detection modules to identify trend/consolidation rhythms more accurately improving entry accuracy.

Conclusion

Overall, the core strength of this strategy lies in price action-based judgments, avoiding dependence on indicators and maximally reflecting market nature. Combining trends and indicators improves profitability while stop loss/take profit controls risk. But risks like larger time frame trend reversals, price pattern failures need to be addressed. Future improvements can come from machine learning, dynamic parameter optimization, risk management modules etc. to make the strategy more robust.
