Investors & landlords

I personally don’t own a business. I just do this as another source of income. I know OANDA is regulated.. I actually use a non regulated broker out of pure ignorance and have access to the total loss amount. I’m guessing this is treated the same way? As I lost $12,000 and am trying to make sure I’m doing the correct thing. I still treat it as “other income” and provide the -$12,000 in the box correct? Thanks in advance!!
