GBP/USD is the most volaitile currency pair. But in recent times it is the most unpredictable currency with sharp non-technical changes of direction and sharp fluctation on news.
ZAR can be fun... still remember my miss at USDZAR 13.80 a couple of years back when I was requoted 13.20, turned it down as being a ridiculous requote even though the bid ask spread had widened over those days to around 5 cents, saw the next quote at 13.79 and then never saw those levels again. That could have been a retirement trade...
Not looked at GBP/ZAR but USD/ZAR is great fun for this side of the fence! Get on the right side GJ! Quit that job and its long hours and get back into the retail side, much easier on the lifestyle and just as much money. Maybe
