@Mr-Pip I am sorry to hear this…Personally I have never heard of Forttrade but luckily they are regulated by the FCA so you should get your money back.
What reasons are they giving for not returning your money?
Generally, Brokers can take up to 5 days to return clients money. It may be an instant deposit into your account but they are allowed some leeway when it comes to returning the money.
In the future, it might be best to withdraw in several orders. Instead of one big one because they might think you are leaving their platform
I am always skeptical of brokers that have been regulated by foreign and questionable governments like Belarus.
