Overview

Enterprise Edition Only Feature.

The Three Line Break chart is popular in Japan for financial charting. These charts display a series of vertical boxes ("lines") that reflect changes in price values. Similar to KagiRenko, and Point & Figure charts, the Three Line Break chart ignores the passage of time.

The Three Line Break charting method is so-named because of the number of lines typically used. Each line may indicate "Buy", "Sell", and "trend less" markets. An advantage of Three Line Break charts is that there is no arbitrary fixed reversal amount. It is the price action which gives the indication of a reversal. The disadvantage of Three Line Break charts is that the signals are generated after the new trend is well under way. However, many traders are willing to accept the late signals in exchange for calling major trends.

The sensitivity of the reversal criteria can be set by changing the number of lines in the break. For example, short-term traders might use two-line breaks to get more reversals, while a longer-term investor might use four-line, or even 10-line breaks to reduce the number of reversals. This is done using the NumberOfLinesInBreak custom attribute.

Working with Three Line Break Charts

The following should be taken into account when working with Three Line Break charts:

 

Note

The Three Line Break Chart Type cannot be combined with any other Chart Types.

 

Using Custom Attributes

You can use custom attributes to fully customize the Three Line Break chart. These custom attributes include: UsedYValue, NumberOfLinesInBreak, and PriceUpColor attributes.

The UsedYValue attribute, for a Series with multiple YValues, defines a zero based index value of which Y value to use. If this value is not specified, the Three Line Break chart will use the first YValue  which is at index 0 in the series.

Example

This example demonstrates how to use the UsedYValue custom attribute.

Visual Basic Copy Code
Imports Dundas.Charting.WinControl
  ...

Chart1.Series("Series1")("UsedYVale")="3"

C# Copy Code
using Dundas.Charting.WinControl;
  ...

Chart1.Series["Series1"]["UsedYValue"]="3";

 

The NumberOfLinesInBreak defines the number of lines to use in the Three Line Break. The default value is 3.

Example

This example demonstrates how to use the NumberOfLinesInBreak custom attribute.

Visual Basic Copy Code
Imports Dundas.Charting.WinControl
  ...

Chart1.Series("Series1")("NumberOfLinesInBreak")="2"

C# Copy Code
using Dundas.Charting.WinControl;
  ...

Chart1.Series["Series1"]["NumberOfLinesInBreak"]="2";

 

The PriceUpColor custom attribute defines the color to use when the Three Line Break chart is on an uptrend. The Three Line Break chart will use the default series color when its on a downtrend. Colors may be specified by their known color names, or by RGB values (commas are escaped using the '\' character).

Example

This example demonstrates how to use of the PriceUpColor custom attribute.

Visual Basic Copy Code
Imports Dundas.Charting.WinControl
  ...

Chart1.Series("Series1")("PriceUpColor"]="0,128,255" ' Blue

C# Copy Code
using Dundas.Charting.WinControl;
  ...

Chart1.Series["Series1"]["PriceUpColor"]= "0,128,255"; // Blue
