Parsing RSS News Feeds in MQL4 for Trading Indicators

Article MQL5 articles

Summary

The article presents a basic approach for reading RSS data in MQL4 and extracting news fields such as event titles and associated currencies. It treats RSS as structured XML, downloads the resource through Windows Internet functions, converts the response string into an array, and reuses HTML tag parsing utilities to locate tag boundaries and retrieve their contents. The example processes event blocks and prints selected fields to the terminal.

The evidence is a script output showing news titles and currency identifiers, rather than a trading or forecasting evaluation. The method is a prototype that could be extended into a news reader or indicator, but it relies on HTML-oriented parsing functions for XML and is described as less convenient than dedicated XML libraries. It also depends on external network access and a particular feed structure, so feed variations and parsing robustness are not assessed.

Key ideas

  • RSS provides structured news data that can be consumed by an MQL4 program.
  • The example downloads a feed and converts its response into an array for parsing.
  • Tag parsing functions extract event titles and country or currency fields.
  • The demonstrated output is printed to the terminal and could support a later news indicator.
  • The approach is a prototype with parsing limitations compared with a dedicated XML library.
