Good day. Please, I got robbed and my iPhone stolen. My password was also obtained at gunpoint and my iCloud has been logged out on the phone. How do I find the phone now?

If you think your Apple ID has been compromised. 

As already correctly answered by Kurt Lang, once signed out of your Apple ID, the phone cannot be tracked.

You need to immediately do the following:

1. Go to www.icloud.com and change your Apple ID Password (you don't need to change your Apple ID - just the password)
2. File a theft report with your police, if you haven't already and get a copy of the report
3. Contact your cellular provider and ask them to blacklist your iPhone, if they offer such an option. You will need to provide the police report you received.
4. Buy a new iPhone as you'll never see the one which was stolen again

If your iPhone is lost or stolen. 

No, you cannot track it. Once they had your iCloud ID and password, the first thing they did was log it out of your account so the phone could be erased and used as new.
