Once you have decided which stock to buy or sell on the stock exchange, you must either enter the order yourself (via S-Net), or ask your banker to enter an order to execute your transaction on your behalf. You’ll have to choose the most appropriate stock exchange or market, taking into account the volume of securities traded and the transaction costs. In order to avoid a possible surprise concerning the stock price, we do  recommend to enter a limit for the price of the security which is the subject of your transaction. This limit usually remains in effect until the end of the current month. However, be careful not to enter a limit that is too far from the current stock market price, as this could result in your order not being executed at all or only being partially executed.
