The strategy is named “Bollinger Band and RSI Mixing with DCA”. It builds trading signals based on the Bollinger Band and Relative Strength Index (RSI) indicators and manages risks using progressive dollar cost averaging (DCA). The main idea is capturing the trend in a bull market using the indicators and reducing costs in a down market through progressive DCA.
The strategy integrates the Bollinger Band and RSI indicators. The Bollinger Band clearly judges the trend where above the middle band means a bull market and below means a bear market. RSI indicates overbuying and overselling situations. The strategy builds a MIX indicator by weighting the Bollinger band deviation and the K value of RSI. A long signal is generated when the MIX indicator breaks through 20 from below.
For the progressive DCA part, an initial position is opened when MIX breaks through 20. Additional positions are added at a fixed amount every time the price drops by a fixed percentage. This is continued until the maximal positions are reached or stop loss/take profit is triggered. By adding positions at market lows multiple times, the average cost can be lowered progressively.
Combining two indicators improves signal accuracy by a clearer trend judgment.
The progressive DCA lowers cost basis during declines, reducing loss risk while increasing profit range.
Take profit and stop loss conditions promptly control risks and lock in partial profit.
Added date range filter allows focused backtests and optimizations of specific periods.
Both Bollinger Band and RSI may suffer failures. Different parameter combinations can be tested for best signal accuracy.
Progressive DCA can increase loss during big crashes by continuously adding positions. Maximal entries can be set along with proper stop loss level for better risk control.
Black swan events and abnormal price moves cannot be foreseen. Systemic risk filters using major indices can help avoid anomalous periods.
Test and optimize parameters for the MIX indicator to obtain more accurate trading signals.
Optimize stop loss, take profit parameters for best profit/loss ratio.
Test different adding position sizes and frequencies to find optimal combinations.
Consider adding trading volume control modules to open/close strategy based on volume conditions.
The “Bollinger Band and RSI Mixing with DCA Strategy” combines multiple quantitative techniques and methods. It builds a clear trend judging indicator and lowers cost basis through progressive additions. Strict risk control methods including stop loss and take profit makes it practical. Further tests and optimizations can unlock its unique advantages into a profitable trading system. With both profit seeking and risk control in mind, it is worth verifying with live trading and applications.
