The Realized Gain/Loss tab details actual gains and losses, by both dollar amount and percentage of individual positions, once sales transactions are complete. A year-to-date listing of all gains and losses is provided by default. You may also view your tax lots by account, by short-term or long-term, or by a date range as far back as seven years. You’ll also find a convenient summary total at the top of the page. Please note that the gain/loss information in this tab is provided for your convenience. However, you should rely on your 1099 form to report gains and losses on your tax return.
