The term "order" refers to how a trade is entered and exited. There are many different types of orders you can place on the market. You can choose to execute a trade at the current market price, or you can create a conditional order to execute a trade at a future market price (which can be higher or lower than the current market price).
Market Order
Open a buy or sell position immediately at the current market price.
Limit and Stop Orders
The order will enter the market and when a pre-defined price is reached, a position will be opened.
Pending Order
An order to open a position at a future price. The order will enter the market and when a pre-defined price is reached, a position will be opened.
Choose one from two orders
Two orders combined into one: When one order is triggered, the other order will be automatically cancelled.
