This is the time to test the “top” in stages from SanDisk, and you can only try it around 1838. Since this area is where the overall pullback from the 2375-972 total decline has recovered 61.8%, then it’s likely the peak of this rebound. The high-altitude idea here is: place a short at 1828/1838 with an initial position; if it breaks below 1770, add to the short; and if it drops below 1720, add again. In the early half of each sequence where longs and shorts alternate, that’s the golden time to add positions. Once you reach the “fish body” and “fish tail,” it’s already too late to keep adding. For the initial position, you usually don’t need to defend it—only players with very heavy position sizing and a 100x leverage need to defend. 1850 is the stop-loss point. As long as 1850 is not breached, it will definitely go down. If 1850 breaks, it can surge toward around 1880. Short again around 1880, and take loss at 1900.

The “fish tail” usually brings a turning point. Before the reversal, if you add positions, you’re likely to be hit hard on the flip. Similarly, even if it can still rise a bit above 1838, don’t chase longs. US stock futures contracts and crypto both heavily emphasize mathematical logic.
