ABCC is a world-class exchange that allows you to trade through market orders or limit orders. Purchase orders are automatically sold or purchased at the current market price. All you have to do is enter the amount you want to buy or sell. Restriction rules let you set a sale or purchase price and wait until the market price matches that price. For these orders, you can specify the amount you want to buy or sell and the price you want to make. Your order will not be placed until the purchase price reaches your limit order.
