Summary

The document explains XML-RPC as a way for MQL5 programs to call remote procedures over HTTP using XML-encoded values. It introduces the protocol’s basic and compound data types, request and response structures, and success and fault responses. It then describes an MQL5 client framework that maps values and arrays into the protocol, while noting that the implementation does not cover the full specification and lacks base64 support.

Two examples demonstrate the framework: calling an external forex service and querying a custom server that analyzes Automated Trading Championship 2011 data. The examples show how remote services can provide results to a MetaTrader client, including contest statistics. The article is chiefly about software integration and data access, rather than a trading strategy or evidence of improved performance. Its framework is presented as ongoing work, and the server-side analyzer and external service are specific examples rather than a general evaluation of reliability or analytical validity.

Key ideas

  • XML-RPC uses HTTP to transport XML-encoded remote method calls and results.
  • Its data model includes scalar values as well as arrays and name-value structures.
  • The MQL5 framework converts supported MQL5 values into requests and parses returned responses.
  • The examples connect MetaTrader to an external forex service and a server analyzing trading contest data.
  • The implementation is incomplete, and the examples do not establish improved trading performance.
