AquilaTrades Brother's strategy is to join when he can't win:

He closed a long position of 15,000 ETH at a price of $4405, which he opened at $4309, making a profit of $1.47 million, 20 minutes ago.

Brother's change in direction is quite decisive: after consecutive losses from 3 short positions on ETH, he quickly switched from short to long, resulting in profit.
