Hi mate,

Pre-market for me is 9:50-10am.

Generally large falls (from 10am) will have much larger pre-market volatility than rallies. In the sample group, the one large outlier had an 11pts pre-market fall, which preceded further large falls. So basically if there are any significant pre-market moves, just a reminder to myself to stay alert/run some more scenarios and potentially hedge out some risk.

Consider hedge against black swan event if premarket closes >10pts.

coupla questions for followers of this stack, or Marto :

1.)

what time does the pre market close ?

and 2.)

closes > 10pts ...

does that mean 10 pts above Fridays cash close of 7048 ?

or 10 pts above some other level, like 10 pts over the open trad eof the day or somesuch ?
