Writing/selling Contract Options requires activation of an advanced option profile. For this, we need your written confirmation that you are aware of the risk involved in shorting options and have relevant experience. Kindly contact Saxo's support to request the advanced option profile.
This is only applicable for Contract Options (meaning stock options, options on futures and indices) - you can short sell FX Options without activating the advanced option profile.
