Hello! Last year I traded some derivatives (covered calls and naked puts), and I have incurred some profits and losses. Which form should I use to declare them?

CRA instructed me to use Schedule 3 (Line 151 and 153, but those lines are normally used for bonds, debentures and promissory notes. Is this the proper form to use and if so, how do you enter the premiums amount, expiration dates, number of contracts, etc?
