There is nothing wrong in moving your coins before the fork,but after the fork it is advisable to wait for a couple of days until everything is fine because replay attack is possible in both the chain ,bitcoin gold fork has replay protection but that wont be the case with segwit2x .The first fork on 25th October is bitcoin gold and wait for a few days before moving your coins,make sure you move your coins to another wallet before trying to transfer the new forked coin for better safety.
