How to access Tradings Hours picker?

[Sim22]

Hi there,

is it possible to use a picker for trading hours templates similar to Gui.Tools.InstrumentSelector ?

I can't see one available and yet it is available within the DataSeries UI.

If it is not publically available, then would you please consider making it so.

Thank you.

Hello Sim22,

This is not documented code, but should achieve your goal:

private TradingHours tradingHours;

[NinjaScriptProperty]
[Display(Name = "Trading Hours", GroupName = "Parameters", Order = 0)]
[TypeConverter(typeof(TradingHoursDataConverter))]
public string TradingHoursString
{
	get
	{
		return tradingHours.ToString();
	}
	set
	{
		tradingHours = TradingHours.Get(value);
	}
}

In State.SetDefaults you can set a default string:
TradingHoursString = "Default 24 x 7";

Thank you Chelsea

Edit:

I did have an exception in this raw form if selecting "<Use instrument settings> so I did this:

 
[NinjaScriptProperty]
[Display(Name = "Trading Hours", GroupName = "Parameters", Order = 0)]
[TypeConverter(typeof(TradingHoursDataConverter))]
public string TradingHoursString
{
    get
    {
       return tradingHours.ToString();
    }
    set
    {
         try
         {
 
              if (value != "<Use instrument settings>")
                  tradingHours = TradingHours.Get(value);
              else if (Bars != null)
                  tradingHours = Bars.TradingHours;
              else
                  tradingHours = Instrument.MasterInstrument.TradingHours;
         }
         catch(Exception)
         {}
    }
} 

Referring to Bars or Instrument within the properties section.....will that cause any issues do you think?

Thanks again, you've saved me many hours writing a custom enum.

Hello Sim22,

The TradingHours.Get() is returning a null when using '<Use instrument settings>'.

Try adding:
if (value == TradingHours.UseInstrumentSettings && Instrument != null)
value = Instrument.MasterInstrument.TradingHours.Name;

To have this return the default trading hours template for the primary instrument.

Regarding use the Bar object in the setter, you have a check for null so this should be fine.

I remade it like this since I had to put a condition in here if in case the default template is ETH when RTH bars are used:

 
if (value == TradingHours.UseInstrumentSettings && Instrument != null)
{
     // in case the default template is ETH when RTH bars are used
     if (Bars != null && Instrument.MasterInstrument.TradingHours.Name.Contains   ("ETH") && Bars.TradingHours.Name.Contains("RTH"))
                tradingHours = Bars.TradingHours;
     else
            tradingHours = Instrument.MasterInstrument.TradingHours;
}
else if (value != null)
       tradingHours = TradingHours.Get(value);
else
      tradingHours = TradingHours.Get("Default 24 x 7"); 

Thanks again.
