Using ROC and a DataSeries

[ij001]

Hello there,

I have searched the forums but was unable to find a solution that works for my issue.
In NT7, I am trying to use the ROC Indicator, with a custom data series called sMa.

Example:

Instead of:
ROC(EMA(10), period)[0];

Use:
ROC(sMa[0], period)[0];

However, I get a compile error that says: Argument 1: cannot convert from "double" to Ninja...IDataSeries.
I have declared, initialized, set, etc in the appropriate areas.

Example:
private DataSeries sMa;

sMa = new DataSeries(this);

public DataSeries IsMA
{
get { return sMa; }
}

What can I put instead of sMa[0] in the ROC Indicator?

Thank you

Hello ij001,

Thank you for your post.

The issue is that you need to pass it the whole data series, and sMa[0] is just one value of that series. Try passing sMa instead:

ROC(sMa, period)[0];
