When the trigger was pulled  on  the  trade,  the  followingconditions existed:
                                 NYSE ticks had increased by +200.                                 The S&P futures had started to rally.                                 Other key market leading  stocks  had  alsostarted to rally.                                 Buy programs were starting to kick in.                                 The stock had reached a level down  1  1/16points from the previous close that began to attract some buyers.
                       The stage was then set to climb past the  trap  door.Probabilities now favored the trade because the specialist wanted the  stockto rally so he could move some inventory, buy programs were kicking in,  andmajor S&P stocks were rallying. Institutions buying MRK had to move up  withthe rally and maintain their share of  the  volume  because  the  low-volumedrop after the opening meant they had not bought enough stock at  the  lowerlevels.                       Note:  On your 5 minute charts you are going to  havea 3 to 5 bar reversal on 90% of the trap doors.  You are  looking  for  thatmove back above the high of the low bar if the close of  that  low  bar  wasabove the midpoint or on top of range.  This is a trade can  quickly  changedirection if the dynamics don't remain positive.
