How can I enable writing/shorting of listed (stock and contract) options? Updated June 11, 2021 14:04 Writing/shorting of listed options requires activation of an advanced option trading profile. This is only applicable for stock options and options on futures & indices. In order to enable it, you will have to acknowledge that you are aware of the risk involved in shorting options and have relevant experience by reading and accepting the conditions. To request the advanced option trading profile, please submit a ticket, choosing the option Enable short-selling listed options through the Contact Support page.
