Guild Wars 2

So with the old TP you could list a sell order very low and sellers would be tricked into selling for that price, but the new TP has it’s own scam which is far worse IMHO.

If you list a buy order at the same price or higher than the lowest sell order, the input gets changed to “Buy now” mode instead of “Place buy order”. The effect of which:

• If you up the quantity the TP will automatically up the buy price, even if your input suggests you want to place a buy order
• You cannot place buy orders higher than the lowest sell order

In other words, if a TP player kept relisting 1 item 1c above the highest buy order, no-one can place buy orders any higher than the current highest and anyone who tries will end up paying more than they set it to

This is already being done on items with high quantity. Please fix.

As it may sounds like an exploit I would suggest you to report it through exploits@arena.net too.
