MetaTrader 5 ships a complete economic calendar, and MQL5 can read it throughCalendarValueHistory(). Nothing outside the terminal can. The PythonMetaTrader5
Never miss news-driven moves – use the News OCO Expert Advisor to place pending orders safely around economic releases. Find out more.
So a research script, a dashboard, a bot or a spreadsheet has no way to ask the terminal when the next high-impact release lands. This Expert Advisor is that missing bridge: attach it to any chart and it periodically writes the calendar to a CSV file inMQL5\Files, where anything outside the terminal can read it.
It isstrictly read-only. It never opens, closes or modifies a position.
Five details that matter
- UTF-8 output.
- Sorted by time.
- Written in a single call.
- HTML entities decoded.CFTC S&P 500 ...S&P. Written through unchanged it reaches every consumer wrong.
- A freshness header.
The update time is read from the trade server clock and not from the last tick. With the market closed the last tick stands still, so a file dated that way would look stale while being rewritten every few minutes, and the event window would slide backwards over the weekend.
