$MASK yesterday hovered around 2.5, then today it was pulled up to around 2.9, today it hovered around 2.7, tomorrow it is estimated to break 3. It is advisable to set up short positions around 3.5 and 3.6, take a wave and run, don't get caught in the pattern, it can drop for several hours, but the rise only takes half an hour. Large buy orders are pressing down, making it hard to drop, but going long is also not suitable because the market likes a waterfall effect, triggering stop losses. It's best to set up for short positions, take a wave and run.
