Master Chart Pattern Analysis with Interactive Annotations

Chart patterns are the foundation of technical analysis. Whether you're identifying head and shoulders, triangles, flags, or custom support and resistance levels, the Pineify Chart Pattern Annotator gives you a powerful, free tool to visualize and document your analysis directly on price charts.

What is a Chart Pattern Annotator?

A chart pattern annotator is an interactive tool that allows traders and analysts to draw directly on price charts. Unlike static charting software, our browser-based annotator lets you upload your own historical price data (CSV or JSON format) and add custom drawings including:

  • Trend Lines: Identify uptrends, downtrends, and channel patterns
  • Horizontal Lines: Mark support and resistance levels
  • Rectangles: Highlight consolidation zones and breakout areas
  • Text Annotations: Add notes and labels to document your analysis
