Scipt: ITrend (I think i got this from Ninja forums)

Trying to change the color of the trigger to change to lime when it crosses above the itrend and red when it crosses below itrend.

/*
Price((H+L)/2),
alpha(.07);
Vars:
Smooth(0),
Itrend(0);
Smooth = (Price + 2*Price[1] + 2*Price[2] + Price[3])/6;
Itrend = (1 - .5*alpha)*(1 - .5*alpha)*(Smooth-2*Smooth[1] + Smooth[2]) + 2*(1 - alpha)*Itrend[1] - (1 - alpha)*(1 - alpha)*Itrend[2];
If currentbar < 7
then Itrend = (Price - 2*Price[1]+ Price[2]) / 4;
Plot1(Itrend, "Itrend");
Plot2(Itrend[1], "Trigger");
*/

Thanks for your help in advance.

Is it for Ninjatrader or for another platform ?
It looks like EL, not C#...

It for NT7 may be i copied the wrong lines from the script.


///<summary>

{

Add(new Plot(Color.FromKnownColor(KnownColor.Blue), PlotStyle.Line, "TrendPlot"));
Add(new Plot(Color.FromKnownColor(KnownColor.Red), PlotStyle.Line, "TriggerPlot"));


trend = new DataSeries(this);
trigger = new DataSeries(this);
smooth = new DataSeries(this);


CalculateOnBarClose = true;

if (CurrentBar==0)
{
smooth.Set(0);
trigger.Set(0);
trend.Set(0);
TrendPlot.Set(0);
TriggerPlot.Set(0);

return;
}

int Per1=PeriodsP;
int Per2=PeriodsP;


if(CurrentBar <= 7)
return;

double SmoothTemp = (Median[0] + 2* Median[1] + 2* Median[2] + Median[3])/6;
smooth.Set(SmoothTemp);


double ItrendTemp = (alpha - alpha*alpha/4)* smooth[0]+0.5*alpha*alpha*smooth[1]-(alpha-0.75*alpha*alpha)*smooth[2]+2*(1-alpha)*trend[1]-(1-alpha)*(1-alpha)*trend[2];
//double ItrendTemp = (1 - .5 * alpha)* (1 - .5*alpha)*(smooth[0] - 2*smooth[1] + smooth[2]) + 2*(1 - alpha)* trend[1] - (1 - alpha)*(1 - alpha)*trend[2];
trend.Set(ItrendTemp);

trigger.Set(trend[1]);

TrendPlot.Set(trend[0]);
TriggerPlot.Set(trigger[0]);

Thank you,
