Keeping indicator internal values from prior bar

[roland_nt]

I am building a Fourier transform indicator which calculates 50 values for a certain parameter, let's say the parameter is named "Real".
So there is a Real[0] through Real[49] for the current bar (i.e. bar[0]).
The calculation needs to reference the prior bar's 50 values for Real (i.e. Bar[1]) as well as the 50 values of Real for the bar before that (bar[2]).

What NinjaTrader data type would I use to declare Real so that the prior bar's calculation values are available?

The NinjaTrader DataSeries type
only stores one value for each bar, not 50.

Real is not a straight 2 dimensional array, since that would reset every thing to 0 each time the indicator executes.

I really need sonething like this
(conceptual example only, might not be correct C#)
Real[3] = new DataSeries (this);
to be referenced in code possibly like this
N = Real[0][25] + Real[1][25] + Real[2][25];
and possibly loaded something like this
Real.Set(A*N-1)[0][25];

I do not need to keep any more than 3 bars back worth of 50 values for each bar.

If this is the wrong forum for this question, please direct me to the proper forum.

Hello,

Unfortunately this is outside the scope of what we can offer support for on the forums. You may find what you want over on MSDN because this is a more advanced C# issue.
