Array

[pipsheker]

Hi,

I am not very good in "C". I have tried to use array but always encounter error. Below is my simple code for experiment:

protected override void OnBarUpdate()
{
if (CurrentBar == 0)
Value.Set(0);
else
{
double mean = 0;
double trend = 0;
double[] w;
for (int idx = Math.Min(CurrentBar, k3m - 1); idx >= 0; idx--)
w[idx]=idx;


What is my problem?
******************
1) I am not sure whether I have define the array correctly:

for example: double[] w;


2) I am also not sure how to place the array command correctly:

for (int idx = Math.Min(CurrentBar, k3m - 1); idx >= 0; idx--)
w[idx]=idx;

Can someone give some advise please? Thanks.

Unfortunately plain C# coding support is beyond the scope what we can provide.

Hint:

double[] w;

only declares an array object. You need to allocate an actual object like

double[] w = new double[yourSize];
