Building an On-Chart Economic Calendar Ticker with MQL5 Canvas

Summary

The article describes an Expert Advisor that retrieves upcoming MetaTrader 5 economic calendar events and displays them as scrolling, color-coded lanes on a chart. It presents the ticker as a way to keep event timing and importance visible during chart analysis without taking space from the chart. The implementation uses the MQL5 CCanvas class to draw and update the display, with user settings for lane visibility and speed, ticker position, offset, and frame interval.

It also explains the calendar’s linked data structures: countries, recurring event definitions, and scheduled event values, including forecast and actual figures. The reported test shows the EA displaying upcoming events with smooth animation, but the article gives no quantitative performance or trading results. A general caution advises avoiding trades around major releases; the ticker itself provides event awareness rather than a tested trading strategy. A live external news feed is described as a possible future addition, while the current news lane is only a placeholder.

Key ideas

• The EA uses CCanvas to draw a scrolling economic calendar ticker over the chart.
• Separate lanes can show high-, medium-, and low-importance events with adjustable visibility and speed.
• MQL5 calendar data links event occurrences to reusable event definitions and country records.
• The display includes countdowns and color-coded importance to help traders notice upcoming releases.
• The article reports a visual deployment test but provides no evidence of trading performance.
