At present, spot trading only supports two order types: market price transaction and limit price transaction
Market order refers to the user's immediate execution of buying or selling at the best price in the current market, in order to achieve the purpose of fast transaction.
Limit order means that the user sets the order quantity and the acceptable highest buying price or the lowest selling price. When the market price meets the limit order price transaction range, the order will be executed.
When the selling order price is lower than the current market price, it will be executed at the market price; when the buying order price is higher than the current market price, it will be executed at the market price.
