Need help to understand where bitcoin transaction has gone
Assuming the address you provided is really your address and not just watch only one there are basically two possibilities:


You have sent the money to another address and forgotten about that (or misunderstood what you are doing),
Your wallet got compromised either by giving private key to some malicious third part or via computer virus which stolen it without your knowledge.


In either way the address you mentioned is now empty and you cannot take the money back unless you control the addresses it is now on.
