Futures Securities in ban?

If I buy a futures contract and that security gets banned, then what happens? Do I have to wait for ban to lift up or what?

Security gets banned only when the open interest in the contract reaches about 90% of the market wide limit. When its banned you can only unwind the position…you are not permitted to any new positions.
