Convert array to series object

[MrSomebody]

Hi all,

Does anyone know the required syntax to convert an array to a series object?

Thanks and regards

Hi MrSomebody, thanks for your note.

There are no existing methods to cast an array to a series. A series object is closely tied to the OnBarUpdate method and will have 1 index for every One would need to manually copy the memory from the array to a series object using a FOR loop, given this does not cause a performance issue.

It is always recommended to use the Series object first as its conveniently managed by NinjaTrader. I made a sort of contrived example:

public class TestCopyArray : Indicator
    {
        private List<double> BigList;
        private Series<double> BigSeries;
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                                    = @"Enter the description for your new custom Indicator here.";
                Name                                        = "TestCopyArray";
                Calculate                                    = Calculate.OnBarClose;
                IsOverlay                                    = false;
                DisplayInDataBox                            = true;
                DrawOnPricePanel                            = true;
                DrawHorizontalGridLines                        = true;
                DrawVerticalGridLines                        = true;
                PaintPriceMarkers                            = true;
                ScaleJustification                            = NinjaTrader.Gui.Chart.ScaleJustification.Right;
                //Disable this property if your indicator requires custom values that cumulate with each new market data event. 
                //See Help Guide for additional information.
                IsSuspendedWhileInactive                    = true;
            }
            else if (State == State.Configure)
            {
                BigList = new List<double>();
                BigSeries = new Series<double>(this, MaximumBarsLookBack.Infinite);

                var count = 0;
                do
                {
                    BigList.Add(Math.Sqrt(Math.Sin(DateTime.Now.Millisecond)));
                    count++;
                }
                while(count < 100);

            }
        }

        protected override void OnBarUpdate()
        {
            if(CurrentBar < BigList.Count) return;
            foreach(var val in BigList)
            {
                BigSeries[0] = val;
            }

            for(int i = CurrentBar; i > 0; i--)
            {
                Print(BigSeries[i]);
            }

            Print("");
            Print(BigSeries.Count);

        }
    }
