Well Im no Guru, but Ill attempt to field an answer.
When the non-farm comes out 4x gets wild. as a rule, if # > forecast, then good for USD. So from your example. If the forecast is -300K and it turns out to be -360K, then you would look for the USD to retreat in most all pairs. Also, an oddity exists in which when that happens, SG usually calls a triple digit DOW run. Has happened the past 3 times that I recall. Hope this helps, and if Im backward, someone please correct me.
BTW, the ADP non farm (preview) was terrible. Even the company that I work for laid-off 10% of the workforce this week. Things are bad, and will probably only get worse.
