Usually I use this to indicate potential shift in trend. The daily Fast line is the preliminary signal and the weekly is a much more reliable one.
Other elements to consider when looking at $SODA's charts are the near 17$ and the 50 weeks line that creates a strong weekly sell zone 16.5-17.5$.
If $SODA will break above 17.5 and close above 18$ it could create a longer term signal that will lead it to a long waited correction move. The momentum in the supports this option.
30$ is the first real weekly structure above 18$ and that's the longer term potential target zone
