爆竹K线训练助手 is a utility application designed for iPhone users, focusing on K-Line simulation training. This app provides a unique feature where stock names and K-Line intervals are hidden, presenting users with an unbiased view of K-Line trends. Users can interact by clicking "buy," "sell," or "hold" buttons to predict the next K-Line trend, with the system calculating profits and losses based on their actions. The training session concludes after 150 K-Lines, allowing for a rapid review of market trends in under three minutes.

The application includes four specialized training modules tailored to different user habits: double-blind training, limit-up training, index training, and futures training. Additionally, it offers various modes such as automatic selling, split position mode, and vibration alerts, enhancing the training experience by closely simulating real trading conditions and accommodating individual trading styles.
