After selecting the crypto/fiat pair, enter the exact amount of crypto you want to buy. In the "Price" section, enter the market price you would like the order to be executed at. This means the price entered will either be higher or lower than the current market price. Click "Buy" and your order will be placed. Follow the same steps for a Sell. Ensure all values are correct before confirming the order.
