P&Fチャートを金融.NETアプリに統合

7月 25, 2025
時間ベースの混乱を伴わずに価格主導のトレンドをプロットし、ポイントアンドフィギュアチャートは、単純なXロジックとOロジックを使用して主要な市場の動きを明確化

A point and figure (P&F) chart is a financial charting technique used to track price movements by plotting directional changes in price without reference to time. It focuses exclusively on significant price changes, filtering out minor fluctuations to highlight clear trends and reversals. Instead of plotting prices continuously, it uses columns of Xs and Os to represent rising and falling prices, respectively, based on predefined price increments. This chart type provides a straightforward view of supply and demand dynamics, making it particularly effective for identifying support and resistance levels, breakout patterns, and trend direction. Its simplicity helps traders and analysts focus on essential price action, reducing the noise found in traditional time-based charts.

Several .NET charting components provide you with point and figure charts, including:

  • ComponentOne Charts for WPF (part of ComponentOne Studio Enterprise by MESCIUS) offers point and figure charts with configurable box sizes and reversal settings for clear trend analysis.
  • Nevron Chart for ASP.NET (part of Nevron Chart for .NET) provides financial web applications with point and figure charts, supporting price filtering and reversal logic.
  • Chart FX 8 Windows Forms (part of Chart FX 8 by Software FX) includes point and figure charts to visualize price trends, support/resistance levels, and reversals without time-based noise.
  • TeeChart .NET for Blazor by Steema Software includes point and figure support to plot non-time-based price movements for financial analysis.
  • Syncfusion WinForms Chart (part of Syncfusion Essential Studio Enterprise) facilitates the use of point and figure charts in Windows desktop applications to analyze price data.
