Exporting MetaTrader Data to Excel Through DDE

Summary

This document outlines a way for a MetaTrader program to send data to Excel in real time through Windows Dynamic Data Exchange. It describes the DDE sequence: initialize the service, identify Excel and a worksheet, connect, address a cell using R1C1 notation, and send values. For repeated updates, the cell handle can be reused; handles and connections should be released when finished.

The accompanying example is described as a small library wrapping DDE functions and a test script that writes text to a worksheet cell. The setup requires enabling DLL imports in the Expert Advisor settings, and the author notes that MetaTrader’s own DDE server may need to be disabled. This is an integration outline rather than a trading strategy or a complete implementation guide; it gives no performance measurements, reliability analysis, or discussion of handling errors and workbook changes.

Key ideas

• Windows DDE can connect a MetaTrader program to Excel for data transfer.
• The workflow identifies the Excel service, worksheet topic, and destination cell before sending data.
• A cell handle can be reused when regularly updating the same location.
• The example requires DLL imports and may require disabling MetaTrader’s DDE server.
