When you 'optimize' your lineup, you'll have two choices: Regular or VIP Waiver.
The VIP Waiver optimizer will recommend add-drop moves with a focus on long-term or short-term.
Long-term looks at the rest of season projections, whereas the short-term looks at the next 7 days.
By selecting 'cancel', the recommended move will not be processed. If you change your mind, you may also 'undo' it.
If you're in a FAAB league, it will ask you to enter a bid amount. You can either A) enter a bid amount or B) leave it blank. If you leave it blank it will send the transactions with the amount and if it isn't needed the operator will ignore the bid amount. If you leave it blank and a player is on waivers, it will default the value to $1.
Pending moves will go to your pending transactions page on the lineup view.
If a player is on the DL, it will not take these players into consideration.
