I have a couple questions for the pro Auction Housers out there. First off, I know that you can get banned for inflating/deflating a particular item too much on the AH. I am not talking about that, I am simply talking about being smart and buying low and selling high (reasonably) and controlling a market to an extent.
1) What methods do you use to pick a market/item to control? More fluid markets obviously have more money potential, but they are difficult and expensive to control.
2) How do you decide when get out of a market if:
a) You have been in the market a while, and just want to get out to not draw too much attention
b) You simply cannot keep up with the number of people undercutting you, so you are gonna throw in the towel and take a loss
