"auto trading disabled by server"

Hello, I have a problem, I installed a robot in MT5, I set everything up, but every time he wants to make a trade, the message "auto trading disabled by server" appears. I'm already desperate, the robot manufacturer says that there is no server and that I have the robot set up well, that I should contact the broker, he wrote me that I have EA enabled, so I do not know where the problem is. I use MT5, the only thing I can think of is that I don't see the "auto trading" button but instead I have an "algo trading" button. I have everything enabled in the EA card.

This is indeed a problem coming from your broker and not the EA or the terminal.

You need to contact your broker and tell them to enable automated trading in your trading account.

Some brokers don't allow automated trading and even expert advisors of any kind in some of their trading accounts, usually those that perform some kind of trading challenge or competition of manual trading.
