I am sharing a weekly chart with one channel detected inside a falling wedge-like pattern. Current engulfing candle suggests further downside towards 1680 level. Failing to hold could send prices quickly to low 1600. Fundamentally speaking there are no relevant factors to support another leg up at the time of writing.
Bulls need to start climbing fast and clear 1800 psychological level followed by 1960.
I'm inclined to follow the current downtrend.
