Thinkscript Volatility Indicator

This is my first post, and I want to be useful and helpful.

I've taken a thinkscripter indicator and modified it slightly.

It's pretty simple - it gives unequivocal long and short signals.

I think it's pretty accurate as is, but can be improved upon.(I'm not a programmer.)

Cheers!

The original is called the Williams Vix Fix and can be found at the thinkscripter website.

(I can't post links yet.)

This version does a pretty good job of indicating trend: --------------------------------------------

Code

                            
declare lower; 
input period = 22;       
def WVF = (Highest(close, period) - low) / (Highest(close, period)) * 100; 
input BBlength = 20; input BBNum_Dev_Dn = -2.0; 
input BBNum_Dev_up = 2.0;       
def sDev = stdev(data = WVF, length = BBlength); 
def MidLine = Average(data = WVF, length = BBlength); 
def LowerBand = MidLine + BBnum_Dev_Dn * sDev; def UpperBand = MidLine + BBnum_Dev_Up * sDev;          ##################     
def down1 = upperband-wvf; 
def up1 =  wvf-lowerband;   plot down = if(down1>up1, expaverage(down1), 0); 
plot up = if(up1>down1, expaverage(up1), 0);  
down.SetDefaultColor(color.green); 
down.SetPaintingStrategy(PaintingStrategy.HISTOGRAM); 
 up.SetDefaultColor(color.red); up.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);

Has this indicator been programmed in NinjaTrader by anyone? If not would it be possible?

Thanks,
