Watch how the stocks react to the routine gap on open. CEPH and JASO have a very high fill rate. Over 80 for both day in and day out. Those are very good odds. AAPL does not get as high a fill rate, but it's range and volatility make it one to play.

As you watch the gaps, ponder an entry and an exit. These can be tough even if you use indicators in that time frame such as MA or stochastics. Also, how would you enter, market or limit order?
