Need simple code for StochRSI please

[TraderTom1]

Hello there,
I use StochRSI indicator a lot in Ninjatrader, however It only display %K line.
I would like it to also display the %D line; StochRSI %D is a moving average of %K over %D Length bars.
I came up with some code by adding D as SMA of StochRSI but it doesn't show the correct results, the D line is way off. can someone help? can I just modify stochRSI.cs and get it done? if so what code should I add and where.

Thank you for your assistance
Tom

Tom, can you please post the code you've come up with so far?

protected override void Initialize()
{
Add(new Plot(Color.Green, "D"));
Add(new Plot(Color.Orange, "K"));

Add(new Line(Color.DarkViolet, 0.20, "Lower"));
Add(new Line(Color.YellowGreen, 0.80, "Upper"));

Overlay = false;
PriceTypeSupported = true;
}

/// <summary>
/// Calculates the indicator value(s) at the current index.
/// </summary>
protected override void OnBarUpdate()
{
double rsi = RSI(Input, periodK, 1)[0];
double rsiL = MIN(RSI(Input, periodK, 1), periodK)[0];
double rsiH = MAX(RSI(Input, periodK, 1), periodK)[0];

if (rsi != rsiL && rsiH != rsiL)
K.Set((rsi - rsiL) / (rsiH - rsiL));
else
K.Set(0);
D.Set(SMA(K, PeriodD)[0]);
}

Never mind I got it, I just had a problem adjusting the smoothing and period length and got diff results, I got it now. I think my formula is correct also.
