When using the NetCents exchange, you are able to place your buy/sell order as a market or limit order. When selecting the market option, the transaction will be immediately processed for the highest current counter offer on the NetCents exchange. Once an order has been submitted and subsequently confirmed, the order cannot be cancelled or modified. When placing market orders, it is important to verify the current counter offers that are displayed on the order book. The order book is visible to the right of your order details on the exchange.
