This morning I went to sell some ARMOR OF DEX, and noticed that there none to be purchased, at the time the going price toll to sell this was around 1.8M;
However since there were none to be purchased, so I listed it at 22M,
Here is we the problem comes in as you list an item for sale and then you can buy that item. You should never be able to be the seller and the buyer, as it is to easy to inflate the market.
Tech Support need to take a look at this and fix the problem.
