Adding Interactive Currency, Importance, and Time Filters to an Economic Calendar Dashboard

Summary

This article describes how to extend an MQL5 economic calendar dashboard with controls for currency, event importance, and time range. Users can toggle the filters from the chart panel, select currencies, and use a cancel control to clear filters and remove dashboard elements. The implementation organizes interface objects with named constants and stores available and selected currencies in arrays.

The dashboard updates its display in response to user actions, with a state flag used to manage whether updates are needed. The article also discusses displaying event details such as country, currency, importance, and time, and says the controls were exercised through interaction scenarios. This is an interface and data-filtering tutorial rather than a tested trading strategy: it gives no evidence that filtered calendar events predict price moves or improve trading outcomes. The described next step, generating trade signals from events, is outside the article’s scope.

Key ideas

• The dashboard provides in-panel controls for currency, importance, and time filters.
• Currency choices are maintained in global arrays so selected filters can change at runtime.
• A state variable helps control when the dashboard refreshes after user input.
• A cancel control clears filters and removes dashboard components.
• The article tests interface behavior but does not evaluate whether calendar filters produce profitable trades.
