Saving startegy parameters: DATETIME variable went retain default value

[talolard]

Hello,
On a startegy I am working on I use user definable datetimt objects. I would like to set default values by right clicking in the backtesting window and clicking "Set default"
While this works for other parameters (of type bool, int or double) it does not work for the datetime variables.
Can something be done?
Thanks
Tal

Hello,

Can you please share the code you are using where you see this behavior? In my testing, I was able to save the user defined Strategy DateTime input parameter as default from the strategy analyzer.

#region Variables
            
		private DateTime myTime = new DateTime(2011,11,23,8,30,00); 
      
        #endregion

 #region Properties
       	[Description("")]
		[GridCategory("Parameters")]
		public DateTime MyTime
		{
			get { return myTime; }
			set { myTime = value; }
		}
        #endregion

wrong code...

So it seems I've been using timespans types

private TimeSpan HWL_LongEnd;

[Description("HWL LongEnd")]
        [Category("Horizontal Wave Long Mode")]
        
		public TimeSpan HWL_LONGEND
        {
            get { return HWL_LongEnd ; }
            set { HWL_LongEnd =  value; }
        }

Will I need to change types, if so can I rely on the some propertys?

To serialize TimeSpan variables please use the following:

    #region Properties
    		
	[Description("HWL LongEnd")]
        [Category("Horizontal Wave Long Mode")]
        
		public TimeSpan HWL_LongEnd
        {
            get { return hWL_LongEnd ; }
            set { hWL_LongEnd =  value; }
        }
		
		
	[Browsable(false)]
	public long HWL_LongEndSerialize

	{
		get { return hWL_LongEnd.Ticks; }
                set { hWL_LongEnd = new TimeSpan.FromTicks(value); }
	}
				
        #endregion

Hi Matthew,
Thanks for your assistance.
Unfortunately, I have implemented the code you provided but the problem has stayed the same. Hours are not saved.
Is there anything else you can think of?
Thanks

You are missing a little piece of the serialization code.

 
[Browsable(false)]
public long HWL_LongEndSerialize
 
{
get { return hWL_LongEnd.Ticks; }
set { hWL_LongEnd = new TimeSpan[B][COLOR=red].FromTicks[/COLOR][/B](value); }
}

Not quite there

Hi,
This is still not working.
The code I have in place is

[Browsable(false)]
	public long HWL_LongStartSerialize

	{
		get { return HWL_LongStart.Ticks; }
		set { HWL_LongEnd = new TimeSpan.FromTicks(value); }
	}

But I get the error

'System.TimeSpan.FromTicks(long)' is a 'method' but is used like a 'type'

Your assistance is appreciated

Hi,
This is still not working.
The code I have in place is

[Browsable(false)]
    public long HWL_[COLOR=red]LongStart[/COLOR]Serialize
 
    {
        get { return HWL_LongStart.Ticks; }
        set { HWL_[COLOR=red]LongEnd[/COLOR] = new TimeSpan.FromTicks(value); }
    }

But I get the error
Your assistance is appreciated

Why are you trying to set LongEnd while you are serializing LongStart?

[talolard]

Good point. But now that I've fixed that, I still have the same problem.
My Code is now

[Browsable(false)]
	public long HWL_LongStartSerialize

	{
		get { return HWL_LongStart.Ticks; }
		set { HWL_LongStart = new TimeSpan.FromTicks(value); }
	}

And I get the same error as before
Thanks

But it does work when I remove the new keyword.
Thanks

Yes, absolutely. For some reason, my eyes just glossed over the "new" keyword. It definitely should not be there. Good catch.
