Binary options on USD / ZAR
USD/ZAR is the dollar against the rand. The rand is thinner than the euro, so the same expiry is a rougher ride. The overnight feed is a different ticker, USD/ZAR OTC.
The rand is the currency of South Africa. The country is a large supplier of gold and platinum-group metals, so the dollar rate listens to metals and to local news. The pair is thinner than the euro.
