    Array

    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.

    Shek

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

    Hint:
    Code:
    double[] w;
    only declares an array object. You need to allocate an actual object like
    Code:
    double[] w = new double[yourSize];
