    Using EMA in an array

    Hi ,

    I am trying to use EMA function to enter values in an array in the following way
    for (i=-24 ;i==0;i++)
    {
    EMA_val[i]=EMA(480)[i];
    EMA_sum[1]+=EMA_val[i];
    }

    getting an error saying that I am trying to use a field like a mathod , I looked in documantion and I am using the script as I should.

    Can someone explain what I am doing worng.

    Thanks

    Hello,

    Since you are using [indx], I assume you are trying to enter values that you can then access later via bar references. Here is a better way to do it:

        Hello Sharkie,

        Ben's suggestion was to create a DataSeries object.
        This tutorial may help illustrate this concept.

        Create a data series and you could then run sum method against the data series you created.

        Using arrays is outside of NinjaScript support. I did notice you're trying to access negative index values. If you pursue this array approach, this is one thing to change. Current bar is accessed with index [0]. The bar prior to this (on the left) is accessed with [1]
