[Resolved]  Olymp Trade — The money I earned

I started trading a few months ago on a special Olymptrade trading account. This is account that each client receives and broker provides 10, 000 dollars as a gift.
I can use this money only for trading.
And you know, I've managed to earn a pretty good amount in a few months.

I currently have $11, 600 in this account and I would like to withdraw $1, 600 since this is what I earned and this money doesn't relate to the initial $10, 000 that was already in my account.

But I ran into a problem and I can't withdraw this money...
