You can place orders using chart context menu, calling new order dialog order by right-clicking on the chart.

But, for learning purposes, it’s much faster to use trading panel on the right side of the chart. Here you can create market and limit/stop orders in a single click, with predefined volumes, stop loss and take profit levels.

You can also modify and delete orders close to the current price if you don’t want to do it with the chart.

Please note that you can modify pending orders, Stop Loss and Take Profit levels by dragging them directly on the chart. It’s much faster than entering prices manually. By the way, the same feature is available in New Order dialog.

You can also drag market order up or down, it will create corresponding Stop Loss or Take Profit levels. If you want to add TP or SL to a limit/stop order, hold Control button when dragging it.
