Renko chart

info

Charts are available with Avalonia Pro.

Renko charts are made of "bricks" that represent a fixed price movement. A new brick is only added if price moves by the specified brick size, filtering out time and minor volatility.

When to use

• Support and resistance: Identifying clear levels where bricks frequently reverse.
• Trend confirmation: Spotting persistent bullish/bearish brick sequences.
• Clean visualization: Simplifying complex, noisy price data into uniform blocks.

Code example

XAML

<charts:RenkoChart Name="RenkoChartSample" Title="Price Movement" Height="300" BrickSize="5"
                                         ItemsSource="{Binding RenkoData}"
                                         ValuePath="Value" />

Data model (C#)

public record RenkoPoint(double Value);

public ObservableCollection<RenkoPoint> RenkoData { get; } = new()
{
    new(100), new(105), new(103), new(108), new(115),
    new(112), new(118), new(120), new(115), new(122),
    new(118), new(114), new(110), new(105), new(100)
