Although the rebound after last Friday's sharp decline is not yet complete, it is also not very strong on an hourly basis, and does not constitute a bullish market for long positions. The rebounds over the past two days have merely been rebounds rather than reversals. There will be another rebound on Wednesday, but it will likely not be comfortable again on Thursday and Friday. In the short term, I still recommend shorting at highs, one trade per day. The best time to open a position this week is between 8-9 AM. If MSTR closes down, it's basically a signal to short as soon as you wake up, because a down close indicates that the US stock market will open lower and decline, with a rebound likely occurring between 4-7 AM, so you can short at the high point (like the short position this morning); if MSTR closes up, it usually oscillates at high points during the day and won't immediately pull back, so you can short at highs between 10 AM and 2 PM, and it will drop in the afternoon from 3-6 PM. This is the rhythm for the past two days.
