The bot will rotate/refresh the contents of Sales window at regular intervals, according to the value configured in the "Repeat After" box. This will position your unsold items at the top of the Item Trader in order to ensure maximum visibility to users looking to buy such items.
When price is being adjusted dynamically, rotating the items in this fashion will also ensure that they're being listed with the latest calculated price, so they can sell as soon as possible.
Once an item was sold, the bot will wait for the time configured in the "Confirm Sales" box before forcing an earlier refresh. This will clear the sold item(s) from the Sales window and replenish the quantity posted for sale.
TIP: You may examine the Log tab to see what actions were performed during sales sessions.
