Overview

This strategy calculates the rate of change over time to determine buy/sell signals. It can help traders capture opportunities in short-term price fluctuations.

Strategy Logic

The strategy is mainly based on the following indicators:

  1. Fast Simple Moving Average (default 14 days): to gauge short-term trend
  2. Slow Simple Moving Average (default 100 days): to gauge long-term trend
  3. Reference Simple Moving Average (default 30 days): to determine overall direction
  4. Rate of Change: calculated based on highest/lowest price over lookback period (default 12 bars) to judge magnitude of price fluctuation

Specific entry rules:

  1. Price below reference SMA
  2. ROC above preset low ROC threshold (default 2.3%)
  3. Fast SMA rising and slow SMA falling, indicating potential crossover

Specific exit rules:

  1. Price above reference SMA
  2. ROC above preset high ROC threshold (default 4.7%)
  3. 3 consecutive rising bars
  4. Current profit > 0
  5. Fast SMA above slow SMA

Position size is percentage (default 96%) of total equity for leverage.

Advantage Analysis

The strategy has the following advantages:

  1. Using ROC to detect swings allows capturing upside/downside moves for higher returns.

  2. Combining fast/slow SMA helps more accurately identify low/high points.

  3. Reference SMA provides overall direction to avoid distraction from short-term noise.

  4. Trailing stop loss locks in profits and reduces downside risk.

  5. Leverage from position sizing amplifies profits.

Overall, the strategy utilizes ROC, SMA and other tools effectively to capitalize on price oscillations. It can achieve good results in volatile markets.

Risk Analysis

The strategy also has the following risks:

  1. Incorrect ROC and SMA parameters may cause missed signals or bad trades. Optimization is needed for different markets.

  2. Excessive position size increases risk. Order percentage should be tested and tuned.

  3. Trailing stop loss may exit prematurely in choppy markets. Stop loss percentage can be adjusted.

  4. Prone to whipsaws in ranging markets. Should incorporate trend filters and risk management.

  5. Backtest overfitting risk. Robustness should be verified through live trading across markets.

Risks can be managed through parameter optimization, position sizing, stop loss adjustments, robustness testing etc.

Optimization Directions

The strategy can be improved in the following aspects:

  1. Add other technical indicators like volatility, volume to improve signal accuracy.

  2. Optimize number of trades by reducing trading frequency to minimize whipsaw impacts.

  3. Incorporate breakout techniques around key price levels.

  4. Use machine learning to auto optimize parameters.

  5. Test robustness across different markets and time frames.

  6. Tune specialized parameters for different products like stocks, forex etc.

  7. Continuously refine signals and risk controls based on live results.

Summary

This strategy identifies trading opportunities around short-term oscillations using ROC and SMA analysis. It helps capitalize on quick swings but also requires proper risk controls. Fine tuning parameters, position sizing, stop losses and robustness testing can enhance its stability and adaptability. The strategy serves as a reference template for quantified trading but needs customization for different markets.
