Talking about BTC at 4 o'clock, I placed an order at 119500 with a stop loss at 119300. This morning, there was a rebound, and it rebounded to above 120000, which was profitable. I was sleeping, so I set a stop loss. If I didn't sleep, I could have taken profits and reduced my position without incurring losses. Then it hit 118652, which is a position where one can go long, but I was asleep and missed it. There's nothing I can do; a person can't stay awake forever. I suggest reducing positions to protect profits around 120000. If there's a rebound to 12.1, go short. If you're anxious, go light on shorts at 12. Anyway, I don't think there's much of a problem below 10.8. After breaking down, there could be further declines. Currently, the market has already rebounded for shorts.
