This strategy is an automated trading system based on candlestick pattern recognition. It integrates ten classic candlestick patterns, including five bullish patterns (Hammer, Bullish Engulfing, Piercing Line, Morning Star, and Three White Soldiers) and five bearish patterns (Hanging Man, Bearish Engulfing, Dark Cloud Cover, Evening Star, and Three Black Crows). Through real-time identification and analysis of these patterns, the strategy provides traders with potential market reversal signals and trading opportunities.
The core of the strategy lies in its programmatic implementation of precise candlestick pattern recognition. Each pattern has its unique mathematical definition and condition criteria:
This is a well-designed and logically clear candlestick pattern recognition trading strategy. It implements traditional technical analysis’s most commonly used candlestick pattern judgments through programming, providing traders with an objective and systematic trading tool. While it has some inherent limitations, through appropriate optimization and combination with other technical tools, this strategy can provide valuable reference signals for trading decisions. The strategy’s modular design also provides a good foundation for subsequent functional expansion and performance optimization.
