Thank you for your comment. What you see is the transition from between bullish vwap and bearish vwap. Since the indicator doesn't use repainting , you may see this frequently based on the swing setting. I can make an alert on this trigger.

Side note: I do not recommend enter trade base on the transition. Best to wait for pullback and rejection off the band. 

I have updated the alert on the indicator. Use it on the chart and tell me if there is any issue or not. Thank you.

The alert should appear like this.

Thank you friend! You get + in karma for a free gift!!!
