When is a Zcash transaction actually complete?

Hello everybody.

I have sent amount of 1.9 ZEC by zcash4win to a wallet in Bitfinex for 7 days.
zcash4win has confirmed the transaction but Bitfinex has not confirmed.
Would you please instruct me on how to know exactly when a Zcash transaction is complete?
This is the transaction ID: 3546416e7095d51e152383802fbe1066f5342837fa8b159e9b9ea1f8ac819720


I check it from block-chain but I do not know how to check if it is success/finish/failure…
Please give me some instruct if you can.

Thank you so much!
