Function Version | Down |
AROONDOWN(x, z) |
x =Period, z =Offset |
Up |
AROONUP(x, z) |
||
Oscillator |
AROONUP(x, z) - AROONDOWN(x, z) |
||
Indicator Version | Down |
AROONDOWNx.z |
|
Up |
AROONUPx.z |
||
Oscillator |
AROONUPx.z - AROONDOWNx.z |
Where x
is the period which must be an integer.
Where z
is the offset. 1 would be 1 bar ago.
Examples
A 100 period Aroon Down can be written is follows.
AROONDOWN100.0
But the offset parameter can be eliminated because is zero.
AROONDOWN100
Which means you can write the 100 period Aroon Up as follows.
AROONUP100
With the 100 period Aroon Oscillator being the following.
AROONUP100 - AROONDOWN100
