FAQ

Is the offline EA builder really free?

Yes — the Windows EXE is completely free: no trial, no watermark, no feature lock, no internet connection needed. The optional $125 source-code license is for developers who want to modify or embed the code.

Does the generated code compile without errors?

Yes. Every generator path was verified through 958 real MetaEditor compilations (MT4 and MT5) with 0 errors and 0 warnings. The app even includes a one-click compile button if MetaEditor is installed.

Does it work without internet?

Yes — the entire builder runs locally. No data is sent anywhere, ever. Your strategy parameters and generated code never leave your computer.

What is the difference from the web builder?

Identical generation engine and features, byte-for-byte. The desktop version works offline, has no server dependency, and keeps everything private — ideal for commercial strategy development.

Is the EXE safe? Does Windows SmartScreen complain?

The EXE is compiled with Nuitka to native machine code (no Python bytecode, no interpreter). Newly released unsigned apps can trigger SmartScreen warnings — click "More info" then "Run anyway". The file is a single self-contained executable.
