What is Market order
Market orders are orders implemented instantaneously at the best immediately accessible price. In this case, the priority of the market taker is given to the speed of making the order, regardless of the related price and fees.
Market orders usually result in higher fees and prices due to a phenomenon called slippage. Slippage occurs when there are not enough sell orders at the best price to satisfy your buy order, and as a result, the next best price orders are purchased.
Limit orders, instead, are orders quantified at a particular price and are not sold or bought by a trader until the price condition is fulfilled.
