i think this would be interesting to have liked we have WTD, MTD and STD it would be interesting to track QTD gain's because in the world of businees that's how they track profits and stuff QTD stands for Quarter-To-Date
here's what each quarter represents
Quarter 1 - January 1- March 31
Quarter 2 - April 1 - June 30
Quarter 3 - July 1 - September 30
Quarter 4 - October 1 - December 31
