Some comments:

- Isn't the capital slider supposed to restrict the trades to 300 EUR? No, it's rather 30 EUR in case of Z12. If you get a wrong margin, please check your asset list.

- .ml files are missing: Does your ML library support multiple cores? Run a test with a single core - are the .ml files then still missing?

- PluginZorroMT4.dll differs from ZorroMT4.zipLibrariesZorroMT4.dll. Is that intended? Yes, it is. Follow the manual for installing the MT4 bridge.
