In the context of financial instruments, executions refer to when a buy and sell trade are completed.
When trading financial instruments, a buyer and seller have to be matched for a trade to happen. When a buyer and a seller with agreeing terms are matched, the trade is then considered to be executed.
There are some important points to clarify about executions.
Once a trade has been executed, they generally can not be canceled. When placing a buy or sell order, please ensure that all of the order details including price and volume are correct before placing the order.
It is also important to use caution when placing special orders.
For example, a market order and a limit order are fundamentally different types of orders. Limit orders buy or sell the asset for a designated price. If the price is too high for a buy order or too low for a sell order, it will not complete until the designated price has been met. However, a market order does not designate a price, just a volume. A buy market order immediately fills itself with the sell orders with the lowest prices.
It is important to understand to understand the specifics of each order type to select the appropriate one.
