Agosto 8, 2025
Os controles gráficos JavaScript com gráficos Kagi reduzem o ruído, destacam os rompimentos e revelam tendências de oferta e demanda na dinâmica do mercado.

Kagi charts are a technical analysis tool that display price movement through vertical lines, ignoring time to focus on significant price changes. Thick lines indicate rising demand when prices break above previous highs, while thin lines signal increased supply when prices fall below previous lows. This clear visual format helps traders filter out noise, identify trends, and spot key breakouts or reversals. Ideal for analyzing market sentiment, Kagi charts are used across stocks, forex, and commodities to support confident, data-driven trading decisions.

Several JavaScript chart components provide Kagi charts, including:

  • Wijmo FlexChart (part of Wijmo by MESCIUS) allows you to interpret price dynamics using Kagi charts, filtering noise to reveal clearer trading signals and sentiment.
  • FusionCharts Suite XT enables Kagi chart rendering to highlight price breakouts and reversals, enhancing clarity in trend-based market visualizations.
  • LightningChart JS Trader lets you visualize supply and demand shifts with Kagi charts for high-performance, real-time financial data analysis.

Julho 25, 2025
Trace tendências orientadas por preços sem desalinho de tempo: os gráficos de Ponto e Figura revelam os principais movimentos do mercado usando a simplicidade da lógica X e O.

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.
