There are several ways to open an order in the MT5 web terminal.
• Go to Menu Bar > Tools > New Order.
• Go to Market Watch, double-click or right-click on an instrument, and select New Order from the context menu.
After pressing New Order, specify the symbol, type of order and volume. Then, press the Buy or Sell button below.
• Press F9 on your keyboard or open the instrument's chart and press ALT+T to jump to one-click trading and open positions with pre-selected parameters directly on the chart. To do this, enable the One-Сlick Trading Panel. Go to Tools > Options and make sure One-click trading is ticked. The One-Click Trading Panel is also available in the Market Watch's Trading tab.
