What is MT4 error 4109?
The MT4 error 4109 is one of the most common errors encountered by Expert Advisor (EA) users. The generic meaning of this error code is Trade Is Not Allowed, which means your EA cannot send an order to your broker server.
After you activate an EA on a chart, the software automatically starts looking for trading opportunities. The MT4 verifies if the bot is allowed for an automated trading operation whenever it requests an order.
The emoticon at the top right of the price chart shows how your expert advisor is doing. A sad emoticon suggests the system is not allowed for trading due to a system setting issue. When you see a smiley emoticon, it means your automated trading system is perfectly up for live trading.
Why does an MT4 error 4109 happen?
You may encounter an MT4 error 4109 due to the following reasons:
An issue with the MT4 settings
If your MT4 is not allowed for automated trading, it will show the error 4109. Since automatic trading is risky, the platform keeps the feature disabled. For instance, if you accidentally activate an EA and are unaware of it, the system may initiate auto trading without your concern. So, the MT4 leaves it up to you to decide whether you want to activate the feature or not.
Your EA is disabled for live trading
It might be another reason why you are receiving the “trade is not allowed” message. Some EA requires manual activation of the live trading option. If you don’t enable the bot for live trading, your system will stop accepting orders requests.
Does your broker allow auto-trading?
Nowadays, almost all the professional broker allows auto-trading. However, by any chance, if your broker doesn’t allow automatic trading operations, the system will be sending the same error code. Sometimes, the availability of such trading facilities depends on the type of account you choose to open with the broker.
