zigzag indicator enter points code on pine script

I am new in pine-script and I have a question about how to get enter point signal of zigzag indicator in trading view. I appreciate if someone can help me on this issue. this code shows the last highest high and lowest low. but it is repainting by moving the price, till another line happen. here like it mentioned in photos i want to use this indicator to show me some signals.
