When the callback to $ETH reaches the four-hour position, note that this position is support! Around 1794! It has already dropped many consecutive red candles, remember to lock in profits! Lock in more profits at 1794, and if you want to exit, you can! Don't enter a short position empty-handed and wait for a rebound to form a death cross before entering short; whether going long or short, don't rush to jump in, and be clear about where to go long and where to short!
