IndicatorBase

[rmk]

Here MobjBase is my Strategy object

internal IndicatorBase getIndicators(IndicatorBase myBase)
{
IndicatorBase indbase;

System.Type indType = myBase.GetType ();
IEnumerable<PropertyInfo> indicatorProperties = this.GetIndicatorProperties (indType);

indbase = (IndicatorBase)Activator.CreateInstance(indType);
indbase.BarsRequired = MobjBase.BarsRequired;

indbase.CalculateOnBarClose = MobjBase.CalculateOnBarClose;

indbase.ForceMaximumBarsLookBack256 = MobjBase.ForceMaximumBarsLookBack256;

indbase.MaximumBarsLookBack = MobjBase.MaximumBarsLookBack;
indbase.Input = MobjBase.Input;

foreach (PropertyInfo info in indicatorProperties)
{
object obj2 = info.GetValue(myBase, null);
info.SetValue(indbase, obj2, null);
}

base.Indicators.Add(indbase);
indbase.SetUp();
return indbase;
}


The above code is working in Ninja Trader 7. I converted these codes to Ninja Trader 8 as below


internal NinjaTrader.NinjaScript.IndicatorBase getIndicators(NinjaTrader.NinjaScript.IndicatorBas e myBase)
{
NinjaTrader.NinjaScript.IndicatorBase indbase;

System.Type indType = myBase.GetType();
IEnumerable<PropertyInfo> indicatorProperties = this.GetIndicatorProperties(indType);

indbase = (NinjaTrader.NinjaScript.IndicatorBase)Activator.C reateInstance(indType);
indbase.BarsRequiredToPlot = MobjBase.BarsRequiredToPlot;
indbase.Calculate = MobjBase.Calculate;

indbase.ForcePlotsMaximumBarsLookBackInfinite =
MobjBase.ForcePlotsMaximumBarsLookBackInfinite;

indbase.MaximumBarsLookBack = MobjBase.MaximumBarsLookBack;
indbase.Input = MobjBase.Input;

foreach (PropertyInfo info in indicatorProperties)
{
object obj2 = info.GetValue(myBase, null);
info.SetValue(indbase, obj2, null);
}

base.Indicators.Add(indbase);
indbase.SetUp();
return indbase;

}


But the following errors are shows.

1.Property or indexer NinjaTrader.NinjaScript.NinjaScriptBase.Input cannot be assigned to – it is read only.

2. NinjaTrader.NinjaScript.Strategies.Strategy does not contain definition for Indicators

3. NinjaTrader.NinjaScript.IndicatorBase does not contain definition for ‘Setup’ and no extension method ‘Setup’ accepting a first argument of type ‘NinjaTrader.NinjaScript.IndicatorBase’ could be found(are you missing a using directive or an assembly reference?)

This is some pretty heavily undocumented stuff, so I have not fully tested my suggestions, please proceed with caution and let me know if you have issues

But the following errors are shows.

1.Property or indexer NinjaTrader.NinjaScript.NinjaScriptBase.Input cannot be assigned to – it is read only.

indbase.Inputs[0] = MobjBase.Input;

2. NinjaTrader.NinjaScript.Strategies.Strategy does not contain definition for Indicators

lock (NinjaScripts)
    NinjaScripts.Add(indbase);

3. NinjaTrader.NinjaScript.IndicatorBase does not contain definition for ‘Setup’ and no extension method ‘Setup’ accepting a first argument of type ‘NinjaTrader.NinjaScript.IndicatorBase’ could be found(are you missing a using directive or an assembly reference?)

indbase.SetState(State.Configure);
