Building an Interactive MQL5 Price Dashboard with Canvas Panels

Summary

This article explains how to build a chart dashboard in MQL5 with the CCanvas library. It describes a graph panel for recent closing prices and an optional statistics panel for account balance, equity, and current-bar open, high, low, and close values. The interface supports draggable and resizable panels, minimize and maximize controls, theme changes, background images, gradients, and updates when new bars arrive. Mouse events, transparency blending, and image scaling are used to render and manage the panels.

The article reports that the components were compiled and visually exercised, with a demonstration shown as an animation. It does not present trading signals, a quantitative evaluation, or evidence that the dashboard improves trading outcomes. Its value is as an implementation guide for custom on-chart monitoring; the displayed statistics and price history are informational tools rather than a tested decision rule.

Key ideas

• The dashboard uses MQL5’s canvas library to draw price and account information directly on a chart.
• Its graph panel plots recent closing prices, while the optional statistics panel shows account values and current-bar OHLC data.
• Mouse event handling supports dragging, resizing, minimizing, maximizing, and theme switching.
• Background images, gradients, and alpha blending provide visual customization.
• The reported demonstration tests interface behavior, not trading performance.
