Do not repeat

Hi

When L1 is crossed below, I want it to draw an arrow on the crossed candle and not do it again until the value of L2 changes.

Now it is drawing an arrow on all the candles that have crossed L1
as picture show

How is that L1 plotted on the chart?

@l-andorrà By zigzag indicator, it means low(by ID)

And are then those arrows correctly drawn? I guess so. You then need to insert the value of L2 into a variable so that when it is changed your request is met.
