Overview
Darwinex DWX Connect functions as a server EA that facilitates communication via file-based messaging, allowing users to execute trades and subscribe to market data without coding in MQL. The EA manages trade requests, provides tick and bar data updates, and includes safety constraints such as maximum order counts and lot size limits. It is designed for custom algorithmic implementations, does not include a native trading strategy, and cannot be used for MetaTrader backtesting.
- Cross-language API for MetaTrader 4 and 5
- File-based communication for tick and bar data
- Configurable maximum order and lot size limits
- Support for asynchronous trading mode
- Automatic chart management for bar data updates
