This is a reference to the market where as a buyer I can go and buy currency for gold or place an offer to sell gold for currency.
As I write this 413 of the 454 market offers are at the minimum price of 0.001 gold per 1.00 GBP. This represents 90% of the offers.
The ability to set a price would be greatly enhanced by a change to quoting the price to cc per unit of gold to match the reverse market.
As an additional effect it would also align the maximum and minimum prices of gold in the two markets since at present you can not place an offer for you to buy gold for more than 1000 cc per gold (ie less than 0.001 gold per cc).
