Why am i banned?

So,i went to go to sleep 2 days ago and i woke up with my account banned for reason "Closed"? that's what it says on my account page "Your account has been terminated due to closed" ? I play on this server for 3 years and i never broke a rule and i was never banned,I was always a role-model player and i still am,I looked from people on global and they said i got banned for "Wintrading",which is apsurd because i don't play arenas at all,i made a ticket and no one is looking at it,can you just please fix your mistake and unban me? I didn't do anything to deserve a ban,i always supported the community and I still do..
