You can set your profit target with a Take Profit order or your loss limit with a Stop Loss order. Upon reaching these parameters, your trade will be automatically closed. You can set either or both of them when opening your trade and any time after you've opened the position.
To set these levels when opening your trade, do the following:
In the Open Trade window, click the Loss and Profit Limits link.
Set your loss limit and/or your profit target.
Select a direction and click the respective button.
To set your profit target and/or loss limit after you've already opened your trade, do the following:
Go to Libertex and select the relevant position from the My Trades list in the dialogue that appears, specify the desired values and click Save.
