With the pre-market rvol & action stocks, I notice that price often moves between levels.  The move between the level is not a straight line, it's often all over the place, but it often hits those key levels.  I think I should look at sell some of my position (25-50%) once the trade goes decently positive, 25-33% when it's 50% to next level, and the remander at the next level.  At the least I need to hold some shares for the next level.
