I have been around runescape for a long time and this has been a partial mistake for 07runescape.
I believe the grand exchange is only efficient when there is a lot of supply/demand for all items. With the current grand exchange setup, you can not see the market depth similar to the trading post.
There should have been more time invested by jagex to customize the grand exchange to fit the economy of 07runescape. Could have been a cross between the grand exchange and the trading post which allowed a more visible market depth of current offers. This would prevent no one sitting there with orders not filled wondering, is it too high? too low? etc
