Passing a BarsArray as a function parameter

[swcooke]

How can I pass a specific BarsArray to a function? Here is what I am trying:

        public void test(double[] myBarsArray){

            Print(myBarsArray[1].Count);


        }

Hello swcooke,

Thank you for your post.

Are you getting an error when you try to compile this?

A BarsArray object would be of the type NinjaTrader.Data.Bars - not a double. Try this:

        public void test(NinjaTrader.Data.Bars[] myBarsArray){
               Print(myBarsArray[1].Count);
        }

Please let us know if we may be of further assistance to you.

I am getting an error. Here is my revised code and the error:

    public class MyCustomIndicator : Indicator

        public void test(NinjaTrader.Data.Bars[] myBarsArray){

Hello swcooke,

Thank you for your reply.

You're not passing the entire array to test().

Try this:

            else if (State == State.DataLoaded) 
             {                 test(BarsArray);             }

How can I pass a specific BarsArray to a function? Here is what I am trying:

 public void test(double[] myBarsArray){

Print(myBarsArray[1].Count);


}

You may be making things harder than necessary.

My suggestion:
Don't pass the array. BarsArray is already global.
Pass the index instead.

public void test(int index)
{
    Print(BarsArray[index].Count);
}

then just call test(1) where '1' is index of the BarsArray you wish to print the Count of.
