The basic idea is that USDZAR will enter a bull trend in an exponential curve, to 100% retracement and beyond in the long term (sorry ZAR, for the rather gloomy picture)... am just proposing potential entry and exit points along the way. As for immediate entry point I would wait for at least two bull Heiken Ashi bars on the 4 HR chart or one bull candle stick on the daily chart.
