Ehlers Indicators Flatlining (NT V7)

February 20th, 2011, 01:23 AM

I just downloaded EhlerCollection v1 for NinjaTrader V7 (bigmiketrading.com/free_downloads/ninjatrader-7/indicators/313-download.html?view)

Most of the indicators in there just flat line when I add them to my chart. It's easier to list those that are OK -- LaguerreRSI, Hilbert Transform2, and iTrend all plot fine. The others flat line.

Any ideas on what is going on?

I tried to PM the provider, but since I am new and do not have enough posts the system will not let me.

Here is the info -- it would be good if someone would pass it along to the provider so he can fix his code to run on NT V7:

-----

Most of the indicators in EhlerCollection v1 flatlline in NT V7.

I noted one error in the output window -- complaining about code in DominantCycle Initialize(). When I moved the following code from Initialize() to OnStartUp(), where it belongs anyway, the error went away and many of the flat lining indicators no longer do.

Code

    _highPass = new DataSeries (this);
            _highPassSmoothed = new DataSeries (this);
            _domCyc = new DataSeries (this);

            _domCycMedian = MedianIndicator (_domCyc, this.period).Value;

            _rgSeries = new FloatSeries [COUNT_PERIODS];

            for (int N = 0; N < COUNT_PERIODS; N++)
                _rgSeries [N] = new FloatSeries (this);

Just thought you might like to know.

The indicators were coded for NT 6.5. and most of them do not work with NT 7.0.

I have made all the necessary changes for NT 7.0 and posted them in the download section.

This was a pleasure to do, as it is really a collection of fine indicators.
