indicator historical data problem

[Pimax]

I want to create my own indicator but i need to use the MACD(12, 26, 9).Diff[1] and i can't get any value from it.

If i use the currentBar for my indicator (MACD(12, 26, 9).Diff[0]), i can see the values.


For example, when i try to add the following indicator to my chart, I can't see any value.

thanks for your help.

protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Dot, "Plot0"));
Overlay = false;
}

protectedoverridevoid OnBarUpdate()
{
Plot0.Set(MACD(12, 26, 9).Diff[1]);
}

#region Properties
[Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
[XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
public DataSeries Plot0
{
get { return Values[0]; }
}
#endregion
}

Hello Pimax,

Thank you for your post.

First, do you see any errors in the log tab in Control Center? This can help you track down what is going wrong.

Also, you are using MACD().Diff[1], saying you want the Diff of one bar ago. But first, you will want to check if you have a bar one bar ago. You can do this by checking CurrentBar, it starts at 0. Ex:

if (CurrentBar > 0)

You can find a full example of checking if you have enough bars at the following link:

Give this a try and let me know if I can assist you any further.
