Gann Horizontal Lines

/--- input parameters
input int            Pivot:= LastValue(Highest(HIGH));
input int            Enter Increment or Decrement
 Ring:=(Sqrt((9 + 12* Pivot))+3)/6;
 Increment:=Input ("Enter Increment or Decrement",   {Increment or Decrement of  Ring of Hexagon} 
 
Target:=(Power(((( Ring-Decrement)*6) -3),2) -9)/12;
 Plot Horizontal Line Red  at  Value of     Pivot:= LastValue(Highest(HIGH));
 Plot Horizontal Line Green at                   Target:=(Power(((( Ring-Decrement)*6) -3),2) -9)/12;

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The brackets are necessary for the precedence in the cal
For the Square Root    how do you apply     MathPow (number ,1/Root )
And to Square the of the number                  MathPow (number ,2 )

 
INPUT_1= START PRICE      // SAY = 150
INPUT_2= INCREMENT       // SAY  = 2
 
PLOT HORIZONTAL LINE =(MathPow((((3 + MathSqrt(9 + 12*START PRICE))/6)+INCREMENT)*6-3),2-9)/12

IN EXCEL FORMULA IS written as      =((( ((3 + (9 + 12*150)^0.5)/6)+2)*6-3)^2-9)/12
