Draw.RegressionChannel()

[pjsmith]

Hello,

Is it possible to retrieve the start and end bar of the upper, lower, and mid lines from a regression channel drawn with Draw.RegressionChannel() ?

Thanks.

Hello pjsmith,

Thanks for your post.

Here is an example:

 protected override void OnBarUpdate()
{
if (State == State.Realtime && doitonce)  // doitonce is a bool set to true, using real time for this example
{
Draw.RegressionChannel(this, "Test", 20, 0, Brushes.Red);  // draw regression channel
doitonce = false;
}

foreach (DrawingTool draw in DrawObjects.ToList())
{
if (draw.Tag == "Test")
{
NinjaTrader.NinjaScript.DrawingTools.RegressionChannel rc = draw as NinjaTrader.NinjaScript.DrawingTools.RegressionChannel;
Bars baseBars = rc.GetAttachedToChartBars().Bars;
int startIndex = baseBars.GetBar(rc.StartAnchor.Time);
int endIndex = baseBars.GetBar(rc.EndAnchor.Time);

double[] myArray = rc.CalculateRegressionPriceValues(rc.GetAttachedTo ChartBars().Bars, startIndex, endIndex);

Print ("Start bar: "+startIndex);
Print ("End bar: "+endIndex);
Print("Upper start Price: "+myArray[0]);
Print("Upper end price: "+myArray[1]);
Print ("Middle start price: "+myArray[2]);
Print ("Middle end price: "+myArray[3]);
Print ("Lower start price: "+myArray[4]);
Print ("Lower end price: "+myArray[5]);
}
}
}
