Using EMA in an array

[sharkie]

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:

Hi Ben,

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]
