fractional values in the optimization parameters

[nichetti]

Hi,

I can not put fractional values in the optimization parameters

Increase in the fractional value is accepted.

In Max and Min not.

For example, 12 turns into 1.2 / 0.6 turns into 6

Here it is:

[Range(0, double.MaxValue)]
[NinjaScriptProperty]
[Display(Name="Amplitude", Order=1, GroupName="Parameters")]
public double AMPLITUDE
{ get; set; }

Hello nichetti,

Thanks for your post and welcome to the forums!

I added your example property code to the sampleMACrossover strategy and ran the strategy in the optimizer. I was able to input decimal values for Min, Max and Increment. (see attached picture).

Can you add more clarity to the issue so that I could further replicate on my end?

I have the exact same problem. I can't enter double values into min and max fields of a double property. I use german windows. It seems NT is confusing parsing of decimals.

Suprisingly increment field works but is displayed different after parsing. Should be "0,1" instead "0.1". I can't change it to 0.123, have to clear the field and write "0,123".

I cannot enter a dot (.) in these fields.

It gets even more confusing when trying to edit the combination field of all 3 values. I can enter the dot there but it gets removed when I tab out of the field. I can't enter comma into that field either.

Hello blueM,

Thanks for your post and Welcome to the forums!

As member Koganam has advised it is the regional settings. Here is a link to the full post Koganam referenced: http://ninjatrader.com/support/forum...301#post431301

Ofcourse its the regional settings but this should be fixed in NT8. It works in NT7 and properly using WPF with globalization in mind is no problem too. Please put that issue into the bugtracker.

Changing Windows regional settings is no solution as this machine is not dedicated to NT only.

Until you introduce region awareness I recommend forcing the culture as hotfix to be set to "en-US" for the whole application like this:

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("en-US");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-US");
FrameworkElement.LanguageProperty.OverrideMetadata(typeof(FrameworkElement), new FrameworkPropertyMetadata(XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));
