#事件合约 tested Binance's new feature. If you open a short position, it will slide down; if you open a long position, it will slide up. Perhaps the exchange thinks the winning rate for opening long is higher? 4 trades: 2 wins and 2 losses. In the last wave, I lost 200 dollars thinking it was over, but who knew it would rise again. In summary, it's just for a little novelty and fun; this thing is suitable for those who like to go all-in, after all, the winning rate for all-in is much lower than this, and all-in has liquidation fees.
