Darwin Evolution MT4 EA V2.35 NoDLL is an Expert Advisor (EA) designed for automated trading on the MetaTrader 4 (MT4) platform. The "NoDLL" in its name likely refers to the fact that the EA does not rely on external Dynamic Link Libraries (DLLs), meaning all the necessary code for the EA is contained within the EA itself, making it easier to install and use without needing additional files.
