I have a FX account and I have put about $20,000 cash into the account. I have had about 4 losing years and last year my account started at about $5,000, a $15,000 loss in the account since I started. This year, my account has risen to $7,000, a $2,000 profit for the year, but still a loss in the account since I opened it. Would I need to pay tax on the $2,000 even though I haven't actually made any money? Please help me understand how losses roll from year to year. Thanks
