This is the opening of a conditional transaction to purchase an tool at the offer price (Ask - see). This price is always slightly lower than the market price. This difference between prices is called the “spread” (see). It is commission that the broker takes when you open a transaction. Buying is also called the "long position" (see), because of the perception that it is necessary to wait longer for profit when buying than selling (see). In order to buy an tool, you need to click on the “New Order” button in your terminal on the top panel above the price chart. In the new window you will see the Ask price for which you have to buy. Once this price has been arranged, click on “Buy”. Just pay attention to what volume (see) of transactions you have set up. If it is too big, you could either not have enough money in your account to open a trade, or the risks could be too high. The most secure transaction is not of a whole lot (see), but parts.
