Turnover/Rollover is your total valid bet amount that excluded cancelled bets, draw result, refunded tickets, and rejected tickets.
For example,
If you bet 3 tickets with each ticket 100,000MMK, and the final result is win/lose/win.
Then your Turnover/Rollover amount will be 100,000 + 100,000 + 100,000 = 300,000.
