(AutoIt) Magyar Nemzeti Bank (MNB) Get Currencies

The Magyar Nemzeti Bank (MNB) is the central bank of Hungary. In this role, its primary objective is to achieve and maintain price stability. The MNB website is available to visitors in both Hungarian and English. The MNB provides the Arfolyam (trans.
