Percent Volume Oscillator (PVO)

The code I have written:

Code: Select all

// PVO - Percent Volume Oscillator - Function

Inputs:
Series ( NumericSeries ), // Volume or Ticks
FastLen ( NumericSimple ),
SlowLen ( NumericSimple );

Variables:
AvFast ( 0 ),
AvSlow ( 0 );

AvFast = XAverage(Series, FastLen);
AvSlow = XAverage(Series, SlowLen);

if (AvSlow > 0) then
PVO = (AvFast - AvSlow) / AvSlow * 100;
I have added EMA instead of SMA! :)

Code: Select all

// PVO - Percent Volume Oscillator - Indicator

Inputs:
AnyVol ( Volume ), // Volume or Ticks
FastLength ( 14 ),
SlowLength ( 28 ),
Zero ( 0 ),
Displace ( 0 );

Variables:
MyPVO ( 0 );

MyPVO = PVO(AnyVol, FastLength, SlowLength);

Plot1[Displace](MyPVO, "PVO");
Plot2(Zero, "Zero");

Thank you very much for the code Laurent. I've been looking for PVO on MC.

Note for others. For the Function code I think it the variables need to be written as follows (with PVO added) as it won't compile otherwise.

Variables:
AvFast ( 0 ),
AvSlow ( 0 ),
PVO ( 0 );

Has Anyone get Laurent's PVO to plot correctly - It compiles, but it's just a flat line on the chart at 0...

Would appreciate it if anyone has got this to work, or has some other code for it.

Thanks
SYn

Hi TJ,

did you get Laurent's PVO to work?

Thank you

I don't remember; it's been a long time.

It works fine.

Code: Select all

// PVO - Percent Volume Oscillator - Function
Inputs: Series(NumericSeries), // Volume or Ticks
FastLen(NumericSimple),
SlowLen(NumericSimple);
Vars: AvFast(0), AvSlow(0);
AvFast=XAverage(Series, FastLen);
AvSlow=XAverage(Series, SlowLen);
if(AvSlow>0) then PVO=(AvFast-AvSlow)/AvSlow*100 else PVO=0;

Hi RRams

whenever i try to compile (compiling as a function or indicator), PVO remains grey and i get the following message with PVO being highlighted.

------ Compiled with error(s): ------
assignment is allowed only for variables or array elements
line 8, column 18

I don't understand what i'm missing

Thanks
Syn

Hello synonym.

The function name itself acts as a variable that can be referenced without declaring in the code. You have to make sure the function name is spelled exactly the same as the variable you reference.

TJ is a wiser man and a better teacher than I. He would send you to the proper links to study the methodology. I don't care as much so here's my code :P

You must be up late!

Thank you for the code RRam! Works great. Comparing yours and mine i simply can't see why it won't compile.
