Continue the oscillating upward approach, today's to tomorrow's high point reference 4730, pullback to 4580-50, extreme pullback to 4510, in the following days the high point will shift up to 4850. 4730-4780--4830-4850 can all be shorted, 4730-4850 can be doubled shorted. This week marks the end of the month, pay attention to the last two days of pullback and sharp drop, which means touching 4850 for a washout, the depth of the washout is uncertain, initially looking at 300-500 points, at the latest at the beginning of next month, breaking new high 5230-5280 to take the opportunity for a washout (800-1200 above). The big pie in the evening is the same, if it does not break 110300, below 110600 can all be long, target 114000-116000. If it breaks, there will actually be a rebound near 110300 giving an opportunity to exit.
