Idea of the Grand Exchange is easy. Every item has a market price. This item can be purchased between a range of 5% below the market price and 5 percent above buy osrs gold the market price. So if a product costs 100 gold, you can buy it between 95 - 105 gold. Now the middle price of the item rarely stays constant.

This is governed by the simple law of Demand and Supply. Now you can sell or buy an item globally. When you set up an offer in the Great Exchange, the system will try to find the closest match as soon as possible. Once it really is found, your offer is going to be complete and you can have the product you bought or the amount of precious metal you sold it with regard to.

But there are certain limits within the Grand Exchange too. It had been done by jagex to prevent wealthy players to 'corner the actual market' by putting up the buy offer for buying a large number of quantity of that item, hence increasing the demand by a lot and raising rs money the price of the item. Even though you can put the buy offer for as numerous items as you want ( or can afford) within the grand exchange, it will treat the offer as a limited one. Assume the limit for an product at 100 gp is actually 1000.
