Trading on an exchange is conditioned by supply and demand. In principle, it can therefore happen with all order types that only a part of the ordered quantity or nothing at all can be executed. Partial executions are not associated with additional costs.
If an order is open, it must also be noted whether a corresponding limit and/or stop price has been added.
- A limit order is triggered by the buy or sell price and executed at that price.
- For stop orders, it is usually because the midpoint between the bid/ask price has not yet reached the stop price of your order.
- For sell orders the bid price is relevant, buy orders are executed at the ask price.
When an order is executed depends on the selected order type and the price development of the security.
