based on zigzag? so arrows repaint or do arrows form after price has moved?

the indicator is not based on a zigzag.

Hello,

Are the alerts issued at once the candle closes?

Do the arrows ever repaint?

Please be specific and detailed.  Thank you

The arrows appear on the start of the second candle, if the conditions. Sometimes the arrows are repaint, very rarely. I can make the arrows appear on the zero bar, but then it will be repaintmore often.
