I noticed it might be because i dont have a paid subscription any more but on the free plan i should be able to use smart trades, however its not working. I cannot import the deal neither place a smart trade for my account.
It was due to hard downgrade to free plan, where existing bots over the plan limit will be closed after some time if the subscription is not renewed. However, it should not affect terminal deals, so we have fixed that. You can try again to import the cancelled deals.
