Price action zone draw

I want an indicator that identifies those types of zones

1.

Low(1)<Low(2)

Close(3)<Low(1)

Low(1)-Close(3)=h 

Draw a zone between Low(1) and Low(2)    Low(2)-Low(1)=r

2. 

High(1)>High(2)

Close(3)>High(1)

Close(3)-High(1)=h 

Draws a zone between High(1) and High(2)   High(1)-High(2)=r

I want a variable for the r ("width of the zone")

so when i set it 3 pips for example to draw zones only when they are equal or bigger than three pips...

and a variable named "multiplier" to draw zones only when h>=multiplier *r

for example when multiplier price is 1.4 and the r=1 it will draw the zone only if the h=14 pips

or when multiplier price of the variable is 2.3 and the r=20 it will draw zones only if h=46

Also when "multiplier"=0 then it will draw a zone if Close(3)<Low(1) for first situtation and if Close(3)>High(1) for the second 

When i delete manually a zone i want not to appear again even if i reload the chart
