This is a buy and sell price which you can see when requesting to open or close a position. The difference between the Bid and Ask price is called spread. All charts in the terminal show Bid price. You can also set the function allowing the display of Ask price as well. In order to do this, press F8 on the chart window, where in the tab “General” you need to tick “Show Ask Line”. "Buy" orders are opened under the price "Ask" and closed under the price "Bid". "Sell" orders are opened under the price "Bid" and closed under the price "Ask".
