Dollar Yen stopped after falling 78%

Dollar Yen has stopped the falling after 78% correction from the previous rise. The downtrend continued, but now it is oversold on the 4 hours chart, however the Daily chart gives reason to expect a continuation of the fall after the MACD crossed the signal line and the chart crossed the EMA100 level. The fall can be extended to 108.75 and 108.4, where there are support levels, but only after the key level 109.0 passing.
On the 4 hours chart there is an opportunity for a MACD buy signal to appear when the line is crossed.
