Realized gains or losses in Q-MAC

Just for clarity, gain/loss is a category, not an account. Quicken Mac calculates gain/loss on the fly wherever needed. But if you create a transaction report, you can select Investments:Realized Gain/Loss as a category to show in your report.

Similarly, the Schedule D Tax Report will show realized gains/losses, but here they are separated into short- and long-term gains and listed in order of security symbol.

(The Schedule D report uses the program's old reports engine, so it isn't as configurable as other reports using the newer reports engine. So you can't click on a column heading such as Date Sold to sort the report in that order, as you can in a Transactions report. Also note that the default for the Schedule D report is to exclude retirement accounts, while the default for a Transactions report will include all accounts, and you'll likely want to de-select your retirement accounts.)
