Possible time points for injection this week (not just one direction):
Wednesday 21:15: December ADP Employment Change
Thursday 3:00 AM: Federal Reserve releases the minutes of the December monetary policy meeting (high volatility)
Friday 21:30: December Non-Farm Payroll
If only focusing on one direction for long positions, there won't be any confusion about direction, treat everything as a pullback to enter long positions, just pay attention to entry and exit points. If both long and short positions are being taken at the same time, from Wednesday to Friday, be mindful of the need to switch quickly; if there is a significant drop on Thursday morning, a sharp rise is inevitable on Friday night.
