From the current 4-hour structure, as long as the bull flag is broken, there is reason to look towards the 600 level, which will also touch the upper boundary of the upward channel. The possible scenario is that it may complete a full 5-wave pattern—Wave 4 drops sharply, Wave 5 reaches the top, and finally forms an M-top at 600. However, even if it doesn't follow the 5-wave pattern, based solely on the structure of the bull flag, it will likely form a top around 600. Once a top is seen here, it will be possible to discuss a larger-scale Wave C correction, meaning a break below the current upward channel, which would completely end the B-wave rally.
