Disadvantages

Limited Strategy Scope: Specialization in only Harami patterns means missed opportunities from other trading strategies during certain market conditions.

Market Condition Dependency: Performance depends on market environments favorable to reversal patterns; may struggle during strong trending periods.

False Signal Risk: No pattern recognition system is perfect; some authentic-looking patterns may fail to produce expected reversals.

Capital Efficiency: Longer holding periods typical of reversal trading may reduce capital turnover compared to shorter-term strategies.

Broker Execution Sensitivity: Performance influenced by broker spread stability, execution quality, and slippage during volatile periods.

Market Evolution Risk: Effectiveness may diminish if Harami patterns become widely automated and arbitraged by institutional systems.

Configuration Complexity: Extensive parameter options can be overwhelming for traders without technical analysis experience.
