Overview

This strategy is based on single moving average and Bollinger Bands indicator. It generates buy and sell signals when price breaks through the upper or lower band of Bollinger Bands. Also it incorporates the direction of moving average to determine the trend, only taking long when MA is rising and short when MA is falling.

Strategy Logic

The strategy mainly uses the following indicators for judgment:

  1. Moving Average (SMA): Simple moving average of CLOSE price, representing the price trend.
  2. Upper Bollinger Band: Represents the resistance level, breakout indicates a strong momentum.
  3. Lower Bollinger Band: Represents the support level, breakdown indicates a possible trend reversal.

The specific trading signals are:

  1. Buy Signal: When close price breaks through the upper band and the MA is rising.
  2. Sell Signal: When close price breaks through the lower band and the MA is falling.

By combining the trend and breakout, the trading signal becomes more reliable and avoids false breakout.

Advantages

  1. Simple and clear rules, easy to understand and implement.
  2. MA judges the general trend to avoid short bull and long bear market.
  3. Bollinger Bands upper & lower band locates local breakout points accurately.
  4. Relatively small drawdowns, matches most people's risk preference.

Risks

  1. Single indicator tends to generate false signals, can be improved by parameter tuning.
  2. Cannot cope with large market fluctuations, can adjust stop loss accordingly.
  3. Unable to profit more from mega trends, can consider larger position size.

Improvements

  1. Optimize MA periods to fit more products.
  2. Add other filters like MACD to reduce false signals.
  3. Dynamically adjust stop loss to limit maximum drawdown.
  4. Introduce money management to stabilize PnL performance.

Conclusion

In general this is a simple but practical strategy suitable for most people. With some tuning and optimizations it can be more robust and adaptive to more market situations. It is a strategy worth recommending.
