Bing Bing is currently at the 0.618 key level, and a head-and-shoulders bottom has already formed. It remains to be seen whether it can break through and retest 1825 on Monday and Tuesday. If it breaks out and then retests, it will most likely move to around 1960 to sweep out short-term liquidity. If it cannot break out or makes a false breakout, it will likely retrace to 1780, then 1720; if it falls below 1720, it will directly drop to 1650.
