Current trend is questionable, uncertain whether it is in segment B - b or segment B - a. The pullback at 88400 in segment B - b is too shallow; if it cannot break below 8.6, the short positions at 8.75 and 8.8 in the previous segment B - a should be partially closed and moved up to breakeven. If breakeven is breached, one can set up short positions near 92000 to target segment B - c. This position is recommended to be held for the long term, as a 5-wave decline is expected, which can refer to the decline amplitude of these 5 waves from 110000 to 74500.
