The answer for me is simple, but effective.  I narrow my watchlist down to 3 stocks, and when the market opens I watch the what I believe will be the quickest mover first and the slowest mover last.  I used chart/price action history and float to make the determination.

1.  $BTSC Bitcoin has moved from 7100 to 7500 so far this weekend.  IF the uptrend continues I will watch $BTSC at the open because these plays tend to spike quickly at the open.  I am choosing $BTSC because it has the healthiest recent uptrend of the bunch.  I'm looking for a break of 0.07 to hold support and possibly test 0.08 in the first 10-20 minutes.  If bitcoin does not continue it's uptrend, I will NOT be watching this one.

 

2. $CERS Earnings winner, high float but heavily shorted (11.6M short, only 3.7M shares traded Friday) and room to run on the daily chart.  This one will likely play out 15-30 min after I'm done watching $BTCS.  Looking for a dip buy at 3.25 or breakout that holds support at 3.60.

 

3. $PRELF OTC pump that panicked Friday afternoon and showed signs of weakness into the close.  If the panic continues, it should be a slow bleed that will play out in 30 min to 2 hours.  Looking to dip buy only a significant panic to the low 2's or high 1's.

 

Of course things will likely change premarket.  If there is a low float earnings or contract winner, I will move it to the top of the list.  A great way to prioritize on a day of multiple premarket winners is to choose the one with the best premarket volume and price action.
