Indicator is a type but it is used as a variable.

[zoki.rb]

// This namespace holds all strategies and is required. Do not change it.
namespace NinjaTrader.Strategy
{
/// <summary>
/// Enter the description of your strategy here
/// </summary>
[Description("Enter the description of your strategy here")]
public class SMAOptimizer : OptimizationType
{
#region variables

private int n;
private int numberOfTrades;

private double p;


private DataSeries myTrades;



#endregion

public override double GetPerformanceValue(SystemPerformance systemPerformance)
{

numberOfTrades = systemPerformance.AllTrades.TradesPerformance.Trad esCount;






for ( int n = 1; n < numberOfTrades; n++ );

{
myTrades.Set(systemPerformance.AllTrades[n].ProfitCurrency);
}

//next line is error
double p = SMA(myTrades, 10)[0];



return p;


}
}
}



I get error "Indicator is a type but it is used as a variable." whatever I do. Please help

Hello,

Thanks for the forum post.

Unfortunately custom optimization type are not supported.

I did take a quick look however and you have this in a Strategy file. This should not go in the strategy file. Should instead be manually put into the My Documents->NinjaTrader 7->bin->custom->type.

Also, please compare with optimizer types here, do you see any differences between the stock NinjaTrader and yours?

I look forward to assisting you further.

For one thing, you already declared "p" as a double at creation. Your assignation statement should not declare it afresh.

[zoki.rb]

double p is not a problem... also there is no problem with optimizationType... here is another, better example.... I just opened a new strategy and tried making new DataSeries... then put few numbers in it and then run SMA on this DataSeries... that is my question. I still get the same error.

So, to get it straight: I need to calculate SMA with custom DataSeries input. Simple as that.

Thank for replies!

I do not see where your DataSeries is properly initialized - http://www.ninjatrader.com/support/h...ries_class.htm

[zoki.rb]

I corrected the mistake in last example and it works now. Thanks

I spent few minutes with C# tutorial and I actually need SMA to run on my custom array. I thought that DataSeries will do, but I have a custom array of numbers. Is this possible in NinjaScript?

[NinjaTrader_Bertrand]

Great - using arrays is possible in NinjaScript as it's general a C# extention, but unfortunately we could not support the coding aspects of it. The SMA would expect a DataSeries as input, a custom SMA on a list / array could be coded in C# as well.

[zoki.rb]

Thank you. I will try with that
