The United States will release the unemployment rate data for March tomorrow night. The strong US economic data has greatly reduced the possibility of the Federal Reserve cutting interest rates in May. The probability of a rate cut in May has been reduced from 90% last month to the current 50%. From the options data, although there has been a nearly 10% correction this week, the market's volatility expectations are still falling rapidly. Tomorrow is the first weekly delivery after the quarterly delivery. BTC Dvol has fallen below 70%, and the IV downward pressure mentioned at the end of last month is still being released. Recently, block trading has been relatively weak, mainly buying call options after the halving.
