/*
Updates:

   11/2/2006:: Fixed bug that caused the sl var to be set to 1 when a pending
               order was > than the First_Stop_Target value.
   1/23/2007:: Fixed pip calculation. The old way of calculating pips could be
               off by 1 pip, resulting in missed TP or move stops. The new
               calculation is more accurate.
