The initial results looked like there was a possibility of a mild upside edge. Further investigation suggested the edge more likely is non-existent. Below is a profit curve that shows a 4-day exit strategy which should explain why I say this.
From this chart is appears that an edge MAY have been in place during the raging bull of the 1990’s. At that time just about any consolidation was followed by a strong move up. Since the end of 1999, though, the profit curve is a complete flatline. It appears that whatever edge there may have been back then is no longer in effect.
