Further talk on SanDisk short-term trading: you can look at the 1410 level. If it breaks down, then below, around 1385 and 1365 are support. As long as 1300 hasn’t been broken, only do short-term long/short trades.

For the big market signal, 1300 is the trend watershed. If 1350 breaks through to the downside, it implies that 1300 is about to be lost. After 1300 is broken, there is about 200–300 points of room downward, and it will be probed in two rounds.

Below 1300, a rebound will be incubated, creating opportunities for you to short the dip and capture the rich rebound profits.

The no-short zone: below 1400 is not suitable for opening new short positions.

Safe opening zone: for short selling, the average entry price must be strictly controlled at 1465–1530, keeping enough safe distance from the lower support zone to avoid being squeezed back. The logic for adding shorts to an existing position versus opening fresh shorts with no prior position is different; you need to strictly distinguish between profit expectations and risk exposure based on the difference in your position cost. $SNDK
