I dont understand why FortFC decided to choose MT5 as the main terminal, but it is not the most popular trading terminal at the moment. You know, its not reasonable.
Which one should be chosen???
MT4 is the most popular one at the moment, it has the biggest audience. Not all the traders or brokers have switched to MT5 so far, lol.
In this regard, its no big deal. Terminals developers already stopped supporting MT4, this version wont work in the future. Now theyre starting supporting and developing MT5 now.
