Heikin-Ashi chart

info

Charts are available with Avalonia Pro.

Heikin-Ashi charts are a variation of Japanese candlestick charts. They use a modified formula for open, high, low, and close values to filter out market noise and show smoothed trend direction.

When to use

• Trend identification: Finding the beginning and end of a market trend with less volatility.
• Swing trading: Identifying pullbacks and reversals in volatile markets.
• Long-term analysis: Smoothing out day-to-day price fluctuations for a broader view.

                                              ItemsSource="{Binding HeikinAshiData}"
                                              HighPath="High" LowPath="Low"
                                              OpenPath="Open" ClosePath="Close"

Data model (C#)

using System;

public record FinancialPoint(DateTime Date, double Open, double High, double Low, double Close);

public ObservableCollection<FinancialPoint> HeikinAshiData { get; } = new(GenerateFinancialData(40));

private static IEnumerable<FinancialPoint> GenerateFinancialData(int count)
{
    var date = DateTime.Today.AddDays(-count);
    var price = 100.0;
    var random = new Random(42);

    for (var i = 0; i < count; i++)
    {
        var open = price;
        var close = open + (random.NextDouble() - 0.5) * 5;
        var high = Math.Max(open, close) + random.NextDouble() * 2;
        var low = Math.Min(open, close) - random.NextDouble() * 2;

        yield return new FinancialPoint(date.AddDays(i), open, high, low, close);
        price = close;
    }
