The eToro platform allows you to set two types of orders: market orders and pending orders.
You can open a market order whenever the market you wish to invest in is closed, which may be during the weekends or other daily market breaks. Placing a market order means that the trade will be executed at the first available rate when the market opens.
You can open a pending order at any time and your order will be converted to a position when the market reaches the target rate you select in the Open Order window. It may be executed within a range of this rate depending on market movements and volatility. The permitted range varies per instrument. For a full list of market ranges per instrument, please visit this link.
In your Portfolio, click on the two opposing arrows to see any orders that have not yet executed into positions:
If you wish to cancel an order, click on the red X on the right. Once cancelled, the funds allocated to that order will be freed up in your account balance and become available for trading again.
