This article analyzes in depth a trend following strategy that combines the SuperTrend indicator with a Stochastic RSI filter for improved accuracy. It aims to generate buy and sell signals while considering the prevailing trend and reducing false signals. The Stochastic RSI filters out false signals during overbought and oversold conditions.
First, True Range (TR) and Average True Range (ATR) are calculated. Then the upper and lower bands are computed using ATR:
Upper Band = SMA(Close, ATR Period) + ATR Multiplier * ATR Lower Band = SMA(Close, ATR Period) - ATR Multiplier * ATR
An uptrend is identified when close > lower band. A downtrend is identified when close < upper band.
During uptrend, SuperTrend is set to lower band. During downtrend, SuperTrend is set to upper band.
To reduce false signals, the SuperTrend is smoothed using a moving average to obtain the filtered SuperTrend.
The RSI value is calculated, then Stochastic indicator is applied on it to generate Stochastic RSI. It shows whether RSI is overbought or oversold.
Long entry: Close crosses above filtered SuperTrend in uptrend and Stochastic RSI < 80 Short entry: Close crosses below filtered SuperTrend in downtrend and Stochastic RSI > 20
Long exit: Close crosses below filtered SuperTrend in uptrend
Short exit: Close crosses above filtered SuperTrend in downtrend
This improved trend following strategy has the following edges over simple moving averages:
This strategy combines the strengths of SuperTrend and Stochastic RSI for effective trend identification and quality trade signals, while also making the strategy robust to market noise through filtering mechanisms. Further performance improvement can be achieved through parameter optimization or combining with other indicators/models. Overall, this strategy demonstrates good trend following ability and some risk control for those seeking steady returns.
