This strategy combines Heikin-Ashi candlesticks and the PSAR indicator for trend identification and trade signals. It uses Heikin-Ashi noise filtering with PSAR for trend reversal detection, aiming to capture medium-long term trends.
Strategy Logic:
Calculate Heikin-Ashi open, close, high and low.
Candle color determines interim bull/bear trend.
Calculate PSAR and identify trend reversal when it crosses Heikin-Ashi price.
Go long on PSAR downtrend and short on PSAR uptrend.
PSAR adapts based on new highs/lows and acceleration factor.
Advantages:
Combination improves accuracy - Heikin-Ashi filters noise, PSAR catches reversals.
Adaptive PSAR adjustable to changing market conditions.
Clear rules benefit parameter optimization.
Risks:
Lagging Heikin-Ashi and PSAR may miss best entries.
PSAR prone to false signals in choppy trends.
Strict risk management needed to defend against whipsaws.
In summary, this strategy pairs Heikin-Ashi for trend context with PSAR for timing. Lag and false signals require caution but can be overcome through optimization for long-term steady gains.
