Help creating this indicator in NT7

Here is a volume indicator I created in Tradestation that seems to be of value...
here is my TS code...

Input: Len(33);

If (Upticks<> 0 and Downticks <> 0) then begin
Plot1(WAverage(Upticks, Len), "volspread1");
Plot2(WAverage(Downticks, Len), "volspread2");

end

Where the TS tick data is set to show trade volume.

In Ninja one would want to use the trade volume at each tick as shown in the time & sales window.

I would really like to have this indicator in Ninja 7 if somone can do it in C# for me....(I do not know C# at all)
An adaptive moving average may be better than a straightforward MA.

Many thanks...
