These are similar to the previous alerts.  They track a stock as it move to new lows or new highs, and then they report when the stock moves 25% or 75% of the way back.  These alerts will automatically choose between the stock's open and its previous close.  They will pick whichever of the two will cause the pattern to be bigger.  This arrangement is particularly popular with Fibonacci traders.
