This strategy combines the Bollinger Bands and Fibonacci retracement indicators for a multi-indicator approach. It belongs to the typical combined indicators strategy type. The Bollinger Bands determine the trend direction and the Fibonacci levels identify key support and resistance zones for generating trading signals.
The strategy is based on two main indicators:
Bollinger Bands
Calculates the upper, middle and lower bands. Price breaking above lower band is long signal, and breaking below upper band is short signal.
Fibonacci Retracements
Calculates the 0% and 100% retracement levels based on historical highs and lows. These act as key support and resistance levels.
The specific trading logic is:
Long signal: Price breaks above upper band, and is above 0% Fibonacci support.
Short signal: Price breaks below lower band, and is below 100% Fibonacci resistance.
Exits are around the middle band for take profit or stop loss.
Risks can be reduced by:
The strategy can be improved by:
Optimizing Bollinger Bands parameters
Finding optimal ratios for upper/lower bands
Optimizing Fibonacci retracement periods
Testing different lookback periods for retracements
Relaxing entry conditions
Observing candlestick patterns on band breaks
Improving exits
Considering trailing stop mechanisms
Product-specific parameter testing
Parameters need tuning for different products
This strategy combines the strengths of Bollinger Bands and Fibonacci Retracements for higher quality signals. But challenges like difficult parameter optimization exist. Improvements can be made through parameter tuning, relaxing entry criteria, enhancing exits etc. to refine the strategy while retaining its edge. Continual adjustments based on backtest results are also key for robustness.
