MQL5 Calendar Utilities for Trading Session and Date Handling
Summary
This document describes an MQL5 date and time library for building trading tools and Expert Advisors. It groups utilities for extracting calendar fields, converting dates, moving through periods, finding boundaries, adjusting business days, calculating durations, and formatting timestamps. Examples show how session checks and news windows can support time-based trading rules. The library also offers faster replacements for standard date conversion functions, according to the document.
The document reports that its calendar difference function was cross-checked against Python date calculations across many intervals, including leap years and month ends, with no mismatches in that validation. This is evidence about calendar arithmetic, not evidence that any trading strategy performs well. Session and economic calendar helpers are mentioned, but their data sources and timezone assumptions are not explained. Traders should verify those details and test calendar behavior against their broker and market conventions before relying on it.
Key ideas
- The library provides helpers for calendar fields, date construction, formatting, and conversion.
- It supports calendar-aware arithmetic, including business days, months, quarters, and years.
- Period boundary and weekday navigation functions can simplify time-based trading rules.
- Session and news checks can be used to gate trading activity by time.
- The reported calendar validation addresses date calculations rather than trading performance.
