What is the difference between Quick Buy/Sell and Buy/Sell?

Advanced Buy/Sell allows you to perform strategic trading on the spot order book by manually using different order types such as Market, Limit, and Stop-Limit. Quick Buy/Sell, on the other hand, enables you to convert your assets within seconds at the best instantaneous price quote without dealing with complex order book processes and order types. In the Quick Buy/Sell module, transaction fees are displayed transparently before confirmation and are calculated based on the market order commission rates in the system.
