There are many ways to place a new order in the MT4 terminal:

1. Click on the ‘New Order’ button on the toolbar
2. Select ‘New Order’ from the ‘Tools’ drop-down menu
3. Press F9
4. Right-click an instrument in the ‘Market Watch’ window and select ‘New Order’
5. Double-click an instrument in the ‘Market Watch’ window
6. Enable one-click trading

Proceeding with any of the above options will open up the ‘Order’ window.

This will let you adjust the parameters of the position you are about to open.

The ‘Symbol’ field allows you to change the instrument and the ‘Volume’ field allows you to set the size of the trade (lot). You may also set stop-loss and take-profit levels.

You then click ‘Sell’ to open a short position at the current bid price or ‘Buy’ to open a long position at the current ask price.
