Usually, T-REX will send you an email for reason if your account is disable or trading function is restricted. However, there are a few common reasons:
1. Your account will be temporarily deactivated as a taker if you cancel 3 orders a day (2 orders for an unverified account) until 00h next day.
However, you can still create an offer to trade.
See how to post an offer on T-REX OTC market.
2. Your account will be permanently deactivated if we find out that you have suspected fraudulent behavior or attempted to compromise our system.
