This is the NinjaTrader code:

Code

High[0]-Low[0] > 2 * (SMA(High,10)[0] - SMA(Low,10)[0]);

Thanks a lot Fat Tails~

Would you also tell me how can I make it just valid if the last bar's signal = false?

In Metastock, I just write like this...

Signal and ref(Signal,-1)=false

Thank you~~

NinjaTrader references the CurrentBar with [0], if you want to reference the previous bar, you would use [1]. The code would therefore be

Code

if (High[0]-Low[1] > 2 * (SMA(High,10)[1] - SMA(Low,10)[1]))

You can also print out the NinjaTrader help file (900 pages), you will find everything needed.

Thanks again Fat Tails, would you suggest any tutorial or ebook which cover more in details about NT programming?

Or should I learn C# first before that?

I would suggest to dig through a book, something like "C# in 20 days". Then just copy and paste code from existing indicators and use the NinjaScript reference. That should do.

Hello,
This is from a "Volume Momentum" Indicator from Barbara Star:

Quoting

Barbara Star discusses volume variations. The title of the article is: Volume Variations.

Mov(ROC(Cum(If(C>(H+L)/2,V,If(C<(H+L)/2,-V,0))),12,$),10,S)

I'm not sure how to do the Cumulative portion of the formula. I'm also not sure about the "$".

Here's my attempt.

Code

//variables:
private int			emaperiod = 10;
		private int			rocperiod = 12;
		private DataSeries	_rocvol;
		

//Mov(ROC((Cum(If(C>(H+L)/2,V, If(C<(H+L)/2,-V,0)))),12,$),10,S)
bool aboveMid = (Close[0]>(High[0]+Low[0])/2);
bool belowMid = (Close[0]<(High[0]+Low[0])/2);

_rocvol.Set(aboveMid ? ROC(Volume,rocperiod)[0] : 
			belowMid ? -1*ROC(Volume,rocperiod)[0] : 0);
			
VolMom.Set(EMA(_rocvol,emaperiod)[0]);

Not sure what the end result would look like but I posted a screenshot of mine...

p.s., is there a MetaStock resource library for Ninjascript porting?
