The concubine has become too strong, breaking through with increased volume and then contracting, with open interest synchronously turning up and continuing to rise. The moving averages for 1h and 4h are both in a bullish arrangement. After this correction on the daily K line, if it continues tomorrow, it will need to open up space to rise and establish a bullish arrangement. Before the breakthrough, there was a reduction in volume, and the increase in open interest leads us to judge that after a period of market action, long positions should take profits and short positions should be established. After being hit, looking back now, this period of market action seems more like increasing positions to go long, and this breakthrough is very healthy.
