unable to withdraw

I opened an account about a month ago. My pnl went from 500 to 400 then to 800, then 600, then took off and I reached 1K. I made maybe 20 traded on DAX and 15 on gold a day on avarage, and was holding position between 2 min and 8 hours. On average I was holding a position for maybe 30min. So relatively short, but I don't think it would violate any rules.That was the point when I decided to withdraw half of it, but then I got this message 1EBnyj5oGkbc"RE: Trading Account Violation Inquiry,We hope this letter finds you well.

Luckily I have deposited only 500 USD, but I would not dare to transfer larger amount like 5-10K to a broker like this.They are not even willing to release my initial capital, so be careful with this broker.I hope it is not over yet.
