Yea, I probably messed up my point.
Resources should have decent value for gatherers (Reasonable Buy orders)
But buying T5+ and especially enchanted Resources in the Royals... Or artifact weapons for example. Either they do not exist or the prices are all over the place.
@Piddle how do you see the name of a listed buy order?
When I was buying with Buy Orders almost exclusively, a long time ago, I found that players are generally smart enough to not sell at predatory prices. Some will sell to you but the volume is a trickle compared to offering them a reasonable price. The average price data is also just right there now, for people to look at, which makes bottom feeding much harder. Right now there aren't a lot of buy orders on Copper Bars in the royals, but instead of people selling for 1-2 silver, they end up bunching sell orders around the listed averages.
