When running custom reports, I assume "Start date" and "End date" to be inclusive. In Trade->Reporting, select "Custom", then May 1 -> May 30. It will show trades that opened on May 2, but not May 1. Change the first date to April 30, and now trades from May 1 will show up (but April 30 trades will not). The reverse is not true - i.e., if May 1 is the end date, it will still show trades from May 1. Feature Request: Either set the dates to be inclusive, or add a tooltip/note that stipulates the difference.
