Set these in worldserver.conf from
./
AuctionHouseBot.Buyer.Alliance.Enabled = 0
AuctionHouseBot.Buyer.Horde.Enabled = 0
AuctionHouseBot.Buyer.Neutral.Enabled = 0
/.
to
./
AuctionHouseBot.Buyer.Alliance.Enabled = 1
AuctionHouseBot.Buyer.Horde.Enabled = 1
AuctionHouseBot.Buyer.Neutral.Enabled = 1
/.
*EDIT*
You can't let your bid in auction there.
Every server shutdown will restart auction bid (Players and AHBot)
so I use these setting for solve immediate problem.
./
AuctionHouseBot.Buyer.ChanceFactor = 5
AuctionHouseBot.Buyer.ChanceMultiplier.Gray = 100
AuctionHouseBot.Buyer.ChanceMultiplier.White = 150
AuctionHouseBot.Buyer.ChanceMultiplier.Green = 300
AuctionHouseBot.Buyer.ChanceMultiplier.Blue = 500
AuctionHouseBot.Buyer.ChanceMultiplier.Purple = 1000
AuctionHouseBot.Buyer.ChanceMultiplier.Orange = 1000
AuctionHouseBot.Buyer.ChanceMultiplier.Yellow = 1000
AuctionHouseBot.Buyer.Recheck.Interval = 1
/.
AHBots will buy your stuff every 1 minute.
When you set items in auction. Don't forget to set their bid and buyout to same amount.
AHBots will bid your item again and again if you set their bid and buyout to different amount,
and that actually lead to a long waiting time before they buy them.
Green items can be set their buyout multiplied from their sell amount at NPC around 2x-3x.
Blue items around 3x-5x.
Purple items around 5x-10x.
