This is the bid price, so the price at which you can buy your desired currency from a broker. If you look at the chart of any currency pair in the terminal (or other tool) and open the "New Order", you will see that you are offered two prices: one price is Ask and the other is Bid (see). It's like at a normal currency exchange, for example to travel abroad you need to buy dollars for rubles. For you, the bank sets the Ask purchase price. It is always a bit higher than the selling price, Bid (see). So, if in the terminal for the currency pair you want to make a deal to purchase (see), ie «Buy», then your transaction will slightly above the price that you see on the chart and you will find yourself with a small loss right from the start. Do not worry, it's just the so-called "spread" (see).
