The time points that may be a needle this week (not just in one direction):
Wednesday 21:15: December ADP employment changes
Thursday 3:00 am: The Federal Reserve releases the minutes of the December monetary policy meeting (large fluctuations)
Friday 21:30: December non-farm
If you only do low-long in one direction, you won’t have any worries about the direction. Treat it as a retracement to go long, and just focus on the advance and retreat of the point. If you are doing both long and short at the same time, you must pay attention to switching quickly from Wednesday to Friday. If there is a big drop in the early morning of Thursday, it will inevitably explode on Friday night.
