Fibonacci pivot calculator

R3 = PP + ((High - Low) x 1.000)

R2 = PP + ((High - Low) x 0.618)

R1 = PP + ((High - Low) x 0.382)

PP = (H + L + C) / 3

S1 = PP - ((High - Low) x 0.382)

S2 = PP - ((High - Low) x 0.618)

S3 = PP - ((High - Low) x 1.000)

Variables  :     OPEN     CLOSE      HIGH       LOW

M1 : Pivot mid level between S1 and S2

M2 : Pivot mid level between S1 and PP

M3 : Pivot mid level between PP and R1

M4 : Pivot mid level between R1 and R2

So when I enter the variables mentioned above I need the values to be given to me in the M1 , M2 , M3 , M4
