Reconciling data from two sheets

I need to reconcile Invoice sheet with the download sheet.
- All the 4 fields should match, Nominal, Trade date, Currency and Amount.
- All the matched data should be copied in Matched sheet, data should tell you whether its from invoice or download sheet.
- Unmatched data only from invoice should be highlighted in Unmatched sheet.

Please note that the data is very huge in the download sheet, some 60k data in Download sheet.

Please,Please,Please,Please,Please,Please some help me
