Acuity Expert Advisor User Experience Improvements

Following feedback from Acuity Expert Advisor users, we have added the following improvements:

• The key required to complete the installation no longer needs to be in the file name (tied to the installer), which simplifies the process for those users that need to install both the MT4 and MT5 versions of the Acuity EAs
• Acuity EA installers now include an option to choose the installer language, improving the user experience for non English speakers.
