The monetary amount of a gain or loss realized from selling shares. If the amount is a loss, it is displayed in red characters with a leading minus sign. On gain/loss screens, if the Gain/Loss is not known, the column is blank, with a hyphen (-) displaying instead of an amount. The gain/loss is unknown when the cost basis is unknown. On the Realized Gain/Loss screen, Gain/Loss may be shown as "Non-reportable" if the position was closed by an action other than a 1099-B-reportable event, for example, the transfer of all shares. In this case, Non-reportable extends into the Term column.
