True zigzag

I need an indicator showing true tops and bottoms by means of lines, and to send an alert when there are three sequential tops with larger decreases than 38.2% fibo and there is a close below the second downturn.

The color of the lines to funds / retractions would be red, and the line for tops / retractions would be blue.

in the example below show how desire to be done.

Fibonacci need not appear, only the lines need appears blue since the retractions achieve more than 38.2% fibo .. The alert will be given below on the first lock from the second retraction.

The calculations are performed from the time the operator connects the indicator.

RULE are tops when there are only hover closing pric the greater than before,

funds exist only when price closed lower than the previous fund;

search by three points or three sequential funds

the indicator should only draw the lines when the retractions of these tops or bottoms are higher than the 38.2% fibo.
