Integrating External Financial News Headlines into an MQL5 Chart Ticker
Summary
The article extends a MetaTrader 5 chart display that already shows upcoming economic-calendar events by adding headlines from an external financial-news API. It uses Alpha Vantage as the example provider, explains API keys, HTTP requests, JSON responses, and extracts headline titles for a scrolling ticker rendered on the chart. The design fetches headlines periodically, with a daily reload schedule, and combines them with the calendar display through timer-driven updates and canvas drawing.
The discussion emphasizes keeping the on-chart display compact by parsing titles rather than full article content, and describes configurable presentation options, importance cues, time handling, error handling, and cleanup. It also surveys alternative providers and their access limits, but those service terms can change. This is a software integration walkthrough, not a trading strategy or a study of whether news headlines predict prices; it supplies no evidence of trading performance or signal quality.
Key ideas
- An MQL5 Expert Advisor can retrieve external news through HTTP requests using a provider API key.
- The example parses headline titles from JSON and displays them in a scrolling chart ticker.
- Timer-based updates and a daily reload schedule coordinate news retrieval and rendering.
- The ticker complements economic-calendar events with a compact visual presentation.
- The article describes integration mechanics but does not test whether headlines create profitable trading signals.
