Please be advised that as of 
December 1, 2024, the minimum supported versions of MetaTrader 4 and MetaTrader 5 trading platforms will be:
MetaTrader 4 build 1420, released on May 24

We recommend upgrading the versions of trading terminals to the minimum supported versions. You can check the version in the client terminal by selecting "Help / About program". If the terminal version is outdated, you can download the latest version 
in your personal cabinet and install it over the current one.
