    JTHMA indicator

    Hi there

    Wonder if the programmers here can help me?

    I have the following JTHMA from a Tradestation indicator:

    Code:
     
    Type : Function, Name : jtHMA
    {jtHMA - Hull Moving Average Function}
    {Author: Atavachron}
    {May 2005} 
    
    Inputs: price(NumericSeries), length(NumericSimple);
    Vars: halvedLength(0), sqrRootLength(0);
    {
    Original equation is:
    ---------------------
    waverage(2*waverage(close,period/2)-waverage(close,period), SquareRoot(Period)
    Implementation below is more efficient with lengthy Weighted Moving Averages.
    In addition, the length needs to be converted to an integer value after it is halved and
    its square root is obtained in order for this to work with Weighted Moving Averaging
    }
    if ((ceiling(length / 2) - (length / 2)) <= 0.5) then
    halvedLength = ceiling(length / 2)
    else
    halvedLength = floor(length / 2);
    if ((ceiling(SquareRoot(length)) - SquareRoot(length)) <= 0.5) then
    sqrRootLength = ceiling(SquareRoot(length))
    else
    sqrRootLength = floor(SquareRoot(length));
    Value1 = 2 * WAverage(price, halvedLength);
    Value2 = WAverage(price, length);
    Value3 = WAverage((Value1 - Value2), sqrRootLength);
    jtHMA = Value3;
    Code:
     
    Type : Indicator, Name : jtHMA
    {jtHMA - Hull Moving Average Indicator}
    {Author: Atavachron}
    {May 2005}
    
    {
    Inputs:
    -------
    price: the time series being smoothed, usually Close, High, etc,
    but could be RSI(Close, 25) for example.
    length: the length of the MA, pretty meaningless in the normal sense
    of moving averages, as this quantity is heavily modified
    in the code. You need to experiment, do not just use a setting
    of 20 because that is what works for you with Simple Moving Averages.
    zeroLine: if you are using this in an indicator pane, you might
    want to display a centre line of some sort, ths allows
    one to set its value
    zeroVisible: boolean variable, determines whether the centre line
    (zeroLine) is plotted.
    upColour: If you wish to differentiate upward movements by colour coding.
    downColour: If you wish to differentiate downward movements by colour coding.
    colourDeltaBar: Set this to 1 if you wish the colour change to be effective on
    the actual bar where the direction change occurred.
    Set this to 0 for default behaviour. All other values
    are pretty meaningless.
    } 
    Inputs: price(Close), length(21),
    zeroLine(0.0), zeroVisible(false),
    upColour(Blue), downColour(Red), colourDeltaBar(1);
    Value1 = jtHMA(price, length);
    Plot1(Value1, "jtHMA");
    If ZeroVisible = true then
    Plot2(zeroLine, "Zero");
    { Color criteria }
    if (Value1 > Value1[1]) then 
    SetPlotColor[colourDeltaBar](1, upColour)
    else if (Value1 < Value1[1]) then 
    SetPlotColor[colourDeltaBar](1, downColour);
    Can someone please help me in translating that to a Ninja C# Code

    Thankyou

    Hi ninjamouse, the Hull MA is already available in NinjaTrader - http://www.ninjatrader-support.com/H...verageHMA.html

    You can find it also under HMA in the 'Indicators' selection list.

      Coolm OK, do you think the code can be changed so that it displays a green/red line depending on if its a up/down trend. Just like this:





      Thanks
