Medium-term, the chart has the potential for a bullish Inverse Head & Shoulders, and looks decently setup for one more wave up. That scenario requires a break above the upper trendline in light blue within the next few months. In the very short-term, prices may exhibit more weakness towards 18800 level, and bounce up to test 19400.
Sustained weakness below lower crucial support of 17500, will change the picture to Bearish. Watch Shanghai & watch out for future updates.
All the best!
