I am trying to make a change to the Zigzag indicator below. In this indicator, the label with the structure of the line is displayed again and again with each new candle.
I want to make the label only show when the higst is high and the end of the line is reached. I tried to intervene in several queries but unfortunately could not implement a reasonable query that only displays the label at the end of the line.
I also considered querying the X and Y coordinates of the line. At the highest high and the end of the line, the old line and the new line should have the same coordinates. So it might be interesting to implement a query that queries the coordinates of the old and new line to query the highest high. So an idea would be interesting how I can display the label only at the end of the line in this indicator
