Only (1) is correct, Ahmad. The reason for this is that appositive clauses are never preceded by a comma. The clause is extraposed because it would be extremely awkward to find it forming part of a long subject in front position:
3. Notice that none shall trade with XYZ from this day onward is hereby given.
We therefore very much prefer your sentence (1) rather than (3). (2) is outright incorrect because of that wrong comma.
