The chart on the xStation platform is drawn based on the BID price, which is the selling price, rather than the price of the last transaction.

To view the ASK price (buying price) on the chart, first, click on the "Visible layers" button on the left side of the chart. Then, select the "ASK" option. The price should now appear in the chart window.

When investing in the financial market, you see both the selling price and the buying price. The buying price is always higher than the selling price, and the difference between these two prices is called the spread, which also represents the cost of opening a transaction on the market.

It is important to remember that when opening a long position (BUY), the transaction will be executed at the buying price (ASK) and closed at the selling price (BID). On the other hand, a short position (SELL) will be opened at the selling price (BID) and closed at the buying price (ASK).
