MACD trend on 4H time-frame of USD/CHF already shifted to bullish. Market tried twice to continue fall after forming AB but could not succeed. Last fall attempt made an evening star (bearish candle pattern) which was later invalidated by morning start (bullish candle pattern). ABCD100 (AB=CD) makes a confluence resistance zone with FIB 50.0 of downswing.
