Aster is currently a 30-minute expansion center. With 0.6807 as a0, it can be seen as a 4-hour double buy (currently lacking a 30-minute double buy confirmation).

Considering the market's current fragility and the poor sustainability of the imitation rebound, viewing it from a oscillation perspective is more conducive to short-term trading, with the maximum operational level being only a 5-minute trend type.
Below the daily level, the oversold rebound logic has already been completed. Currently, there is still one daily rebound logic that has not yet played out, with resistance around 0.85.
If it cannot be touched this week, my expectation will decrease to around 0.815 as time goes on.
