Exporting from 23 - Stochastics Error

[bobcat70]

Trying to export an indicator as an assembly that uses the Stochastics unit. I'm getting the following error in the log when I try to export, but when I compile my unit, there are no errors.

Error compiling export assembly: c:\users\john\documents\NinjaTrader 7\bin\Custom\indicator\@Stochastics.cs(61,29): error CS1061: 'double' does not contain a definition for 'Compare' and no extension method 'Compare' accepting a first argument of type 'double' could be found (are you missing a using directive or an assembly directive).

There is also an error on line (60,29).

I also found this link with new files for Stochastics, but after following these instructions, it still didn't work:

Since I can't change the @Stochastics routine, I assume something on your end?

Thanks
John

agreed

This is certainly true. Here is some more info from a colleague, Vladimir..
.

I've found the source code of the Compare method. It is NT's method, not .NET's method.

It is in this file on my machine:
C:\Users\Vladimír\Documents\NinjaTrader 7\bin\Custom\Type\@BarsTypes.cs

The file cannot be added in the Export NinjaScript Archive File dialog.

Here is the beginning of the file, including the Compare method:
=================================

/// <param name="x"></param>
/// <param name="y"></param>
/// <param name="precision"></param>
/// <returns></returns>
public static int Compare(this double x, double y, double precision)
{
double diff = x - y;
return diff < -precision ? -1 : (diff > precision ? 1 : 0);
}
}
=================================
I compared @Stochastics.cs file from beta 22 and RC1 and they differ. The lines in Stochastics that cause the export error are new in RC1.

Cheers,

bobcat, saltminer, thank you for reporting. I was able to reproduce and I'll send a note along to development.

If you have an interim fix, please let me know. I need to get something out for production. Thanks.

Hello bobcat70,

Unfortunately there is not an interim fix beyond creating your own stochastics.

You can save a copy of the system stochastics by right clicking > Save As within the NinjaScript editor.

Make any modifications in this new indicator.

In your indicator that references stochastics, you would have to update any references to the new indicator you just made.

Thanks for reporting that issue.
We had been able to isolate the cause of trouble and will provide fix with the next update of NT7.

Had the same problem today. Fixed it my manually copying the indicator file that calls the Stochastics.

Waiting for the bugfix now.
