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.
