The Line Study series displays lines or circles a function that aim to study the market behavior and monitor price trends, channels, support and resistance levels, as well as to try to predict the possible future market movement.
The following image shows the a line study:
Trendline series are represented by the NLineStudySeries type. An instance of this type must be added to the series collection of a Cartesian chart:
| C# |
Copy Code
|
|---|---|
NLineStudySeries lineStudy = new NLineStudySeries();
chart.Series.Add(lineStudy);
|
|
The line study is defined by its Begin and End points. The following code shows how to create a line study based on two points:
| C# |
Copy Code
|
|---|---|
NLineStudySeries lineStudy = new NLineStudySeries(); lineStudy.BeginPoint = new NPoint(0, 0); lineStudy.BeginPoint = new NPoint(1, 1); |
|
The line study series type is controlled from the LineStudyType property of the series that accepts values from the ENLineStudyType enumeration:
| C# |
Copy Code
|
|---|---|
NLineStudySeries lineStudy = new NLineStudySeries();
lineStudy.LineStudyType = ENLineStudyType.FibonacciArcs;
|
|
| Line Study Type | Image |
| Line | |
| FibonacciArcs |  |
| FibonacciFans |  |
| QuadrantLines |  |
| SpeedResistanceLines |  |
In the case of line study type Line you can also control whether the control shows the segment of the line defined by the Begin and End points or Beam extending past the End point of the trend line.
By default the control will use automatic retracement values dependent on the LineStudyType for line study types that use them, but you can also provide custom retracement values using the RetracementValues property of the series:
| C# |
Copy Code
|
|---|---|
lineStudySeries.RetracementValues = new NDomArray<double>(new double[] { 0.382, 0.5, 0.618 } ); |
|
The trendline series supports the following formatting commands in addition to the standard (per data point) formatting commands:
<beginX>, <beginY> - represents the Begin property X and Y values respectively.
<endX, endY>- represents the End property X and Y values respectively.
