Using Economic Calendar News Across Live Trading and Backtests
Summary
This article explains how to work with the MetaTrader economic calendar through a unified news structure that combines country, event, and release-value information. It outlines checks for upcoming releases associated with a symbol’s currencies and shows how event importance and timing can be used to flag potentially relevant news. The aim is to reduce repeated calendar-handling code in expert advisors.
It also describes a provider design that exposes a similar interface for built-in calendar data, exported CSV files, and SQLite storage. The built-in source supports live use, while stored data makes historical testing in the strategy tester possible; a shared interface helps keep strategy logic independent of the source. The article offers implementation guidance and examples, not evidence that avoiding or trading around news improves returns. Calendar availability, data quality, and the chosen relevance and timing rules remain practical limits.
Key ideas
- Calendar country, event, and release-value records describe different aspects of an economic announcement.
- A unified structure can combine those records for simpler filtering and storage.
- News filters can match event importance, release time, and currencies associated with a trading symbol.
- Built-in, CSV, and SQLite providers can supply news through a common interface.
- Historical news files can support testing news-dependent logic in a strategy tester.
