MT4Professional 3.0.0 is rewritten from scratch.
To make the transition, we had to change the configurator format slightly. While it is different, it will be much more intuitive and easier to work with. Don’t worry, you won’t lose your previous configurations, but you need to convert them into a format compatible with MT4Professional 3.0.0. Since this is a completely new version, any new configurations cannot be used with old MT4Professional versions. It is now “downward compatible”. As a suggestion, you may rewrite your configurations with the new 3.0 configurator to improve the overall performance, since it’s very easy to rewrite them.
