Cannot convert a double to ISeries Double.

[Conceptzx]

Can someone help me sort this out? I am trying to make the HeikenAshi OHLC's into 4 separate ISeries Doubles so I can use them in Moving Average inputs but I get an error about converting a double to ISeries<double>, not sure what's I'm missing to make the conversion..

private ISeries<double> haOpenSeries, haCloseSeries, haHighSeries, haLowSeries;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Select a Band Type and a MA to reference it off of all in one indicator.

AddPlot(Brushes.Gray, "HAOpen");

}

{
if (CurrentBar == 0)
{
haCloseSeries = Close[0];
haOpenSeries = Open[0];
haHighSeries = High[0];
haLowSeries = Low[0];
return;
}

haCloseSeries = ((Open[0] + High[0] + Low[0] + Close[0]) * 0.25);
haOpenSeries = ((haOpenSeries[1] + haCloseSeries[1]) * 0.5);
haHighSeries = Math.Max(High[0], haOpenSeries[0]);
haLowSeries = Math.Min(Low[0], haOpenSeries[0]);

if (CurrentBar < 1)
return;

double maValue = 0;
switch (MATypesHAMA3)
{
case MATypesHAMA3.ADXVMA: maValue = ADXVMA (haCloseSeries, Period)[0]; break;
case MATypesHAMA3.AhrensMA: maValue = CX_AhrensMA (haCloseSeries, Period)[0]; break;​

Hello Conceptzx,

Thank you for your post.

You are trying to assign a value of type double to the entire series.

If you want to save the double values in the series, you need to supply an index to the series. For example,

haCloseSeries[0] = ((Open[0] + High[0] + Low[0] + Close[0]) * 0.25);

haOpenSeries[0] = ((haOpenSeries[1] + haCloseSeries[1]) * 0.5);

haHighSeries[0] = Math.Max(High[0], haOpenSeries[0]);

haLowSeries[0] = Math.Min(Low[0], haOpenSeries[0]);

Check out the Help Guide page for Series<T>:

https://ninjatrader.com/support/helpGuides/nt8/seriest.htm

Additionally, make sure you instantiate the Series<double> objects in State.DataLoaded. For example,

else if (State == State.DataLoaded)
{
haOpenSeries = new new Series<double>(this);|
}​

Please let us know if you need any further assistance.
