Stock market break time

 Whether the highs or lows are tested or not, the market tends to "drift" for the next hour or more. 

11:45 am(8:45california).–1:30 p.m (10:30 california).: This is lunch time in New York, plus a bit of a time buffer. 

Usually, this is the quietest time of the day, and often, day traders like to avoid it.
